The Doctor

The Doctor is a Gallifreyan Time Lord who travels through time and space in a type 40 TARDIS with various human and non-human companions. In the Lilith!Verse, he is married to Rose Tyler-Lungbarrow. He has five children: Jenny, Lilithanadir Tyler-Lungbarrow, Darkelvoriplorellion Tyler-Lungbarrow, Nyxiusfelania Tyler-Lungbarrow, and Jaminoreniakal Tyler-Lungbarrow.

First Doctor
Lilith appears on the TARDIS for the first time in the Doctor's timeline. He demands to know who she is and she explains that she's his daughter from the future who was sent back to prevent a paradox. The TARDIS arrives on board a spaceship in orbit around a planet called the Sense Sphere. The alien Sensorites have trapped the ship's human crew, Captain Maitland, Carol and John, in a state of semi-permanent sleep. When the Doctor investigates, the aliens steal the lock mechanism from the TARDIS, thus trapping him, Lilith, and his companions. The Sensorites allow all but Maitland and Barbara down to the planet, where Ian contracts a sickness that has been wiping out the Sensorites. The Doctor and Lilith offer to find a cure. Their investigations into the cause of the sickness are hindered by the rebellious activities of the City Administrator, but eventually they uncover three deranged human survivors from a past expedition who have been adding deadly nightshade to the water supply.

Second Doctor
The TARDIS materialises on the planet Dulkis, where the Doctor, Jamie, and Zoe were planning to relax. Lilith arrives, disrupting the Doctor's plan of a peaceful vacation. Aided by their robotic servants, the Quarks, and slave workers drawn from the native Dulcian population, the Dominators set about drilling bore holes, through which they plan to fire rockets into the planet's molten core. Their intention is then to drop an atomic seed capsule into the resulting eruption, turning Dulkis into a radioactive mass - fuel for the Dominators' space fleet. The Dulcian Councillors, being pacifists, refuse to retaliate, although Cully, the rebellious son of their leader Senex, has already joined forces with the time travellers. The Doctor eventually defeats the Dominators by intercepting the seed capsule as it is dropped and placing it on board their ship, which is then destroyed shortly after take off.

Third Doctor
The Doctor is working on the TARDIS console when Lilith appears, insisting again that she is truly his daughter. Sir Reginald Styles, organiser of a world peace conference, narrowly survives an assassination attempt by a combat-uniformed guerrilla who vanishes like a ghost. Later the guerrilla is attacked by huge, ape-like creatures called Ogrons and found unconscious by UNIT troops in the grounds of the house. The Doctor deduces that he comes from about two hundred years in the future and that a device found with him is a time machine. While Styles is away, the Doctor, Lilith, and Jo keep watch. The guerrillas attack again, but the Time Lord convinces them that he is not Styles. One of their party, Shura, is later injured by an Ogron. Jo meanwhile accidentally activates one of the guerrillas' time machines and is transported to the 22nd Century. When the guerrillas return there, the Doctor and Lilith go with them. They learn that the Earth of this period is ruled by the Daleks with the help of the Ogrons and human collaborators, whose leader is known as the Controller. Lilith, Jo, and the Doctor are taken prisoner at the Dalek base. The guerrillas rescue them and explain that they are attempting to kill Styles because he caused an explosion at the peace conference, starting a series of wars that left humanity vulnerable to Dalek conquest - a history that they wish to change. The Doctor realises that the explosion was actually caused by Shura in a misguided attempt to fulfil his mission. Returning to the 20th Century with Jo and Lilith, he has Styles' house evacuated. Daleks and Ogrons arrive in pursuit, but are destroyed when Shura detonates his bomb.

Fourth Doctor
The Doctor and Sarah land on what appears to be Earth and run into Lilith as she stumbles out of the forest. The planet is actually Oseidon, where the alien Kraals have created an exact replica of the English village of Devesham and its nearby Space Defence Station and populated it with androids in order to rehearse for an invasion attempt. A human astronaut, Guy Crayford, has been duped into collaborating with them. The TARDIS travels on to Earth alone, and the Doctor, Lilith and Sarah follow in Crayford's rocket, which is being used to carry the spearhead of the invasion force. The Kraals' chief scientist, Styggron, intends to release a deadly virus in order to weaken resistance to the forthcoming invasion. On reaching Earth, the Doctor, Sarah, and Lilith try to convince UNIT troops at the Space Defence Station of the danger, but with the Brigadier away in Geneva, their attempts fall on deaf ears - Crayford is being hailed as a hero. The Doctor uses the Station's transmitters to jam the control signals of the now active androids - including duplicates of himself, Harry Sullivan and RSM Benton - and prevents Styggron from releasing his virus. Styggron accidentally infects himself during a fight with the android Doctor and is killed.

Fifth Doctor
After Lilith appears, the TARDIS is dragged down to the surface of the planet Frontios and apparently destroyed during a meteorite bombardment. The Doctor is forced to help the planet's human colonists - refugees from a doomed future Earth - and eventually discovers that their problems stem from an infestation of Tractators, burrowing insect-like creatures led by the intelligent Gravis. The Tractators have been using gravitational force to cause regular meteorite bombardments in order to keep the colonists weak so that they can prey on their bodies and use them as components in their mining machines. Turlough knows of the creatures through a deep seated racial memory from his own planet. He recalls that they can be rendered harmless by separating the Gravis from the rest of the colony. The Doctor achieves this by tricking the Gravis into reassembling the TARDIS around itself.

Sixth Doctor
When Lilith arrives on the TARDIS again, the Doctor is lured to Earth in 1985 by a distress call sent by Lytton, who has made contact with a group of Cybermen based in London's sewers. The Doctor, Lilith, and Peri are then captured and forced to take Lytton and the Cybermen in the TARDIS to the Cybermen's home planet Telos. The Cybermen have stolen a time vessel from another race and plan to change history by crashing Halley's Comet into Earth and obliterating it before it can bring about the demise of their original home world, Mondas, in 1986. Lytton is, however, a double agent employed by the Cryons - a species native to Telos. His mission is to capture the stolen time vessel, but he fails and is partially converted into a Cyberman. The Doctor is unable to save him, but manages to kill the Cyber Controller. The Cryon leader Flast sacrifices her own life and a huge explosion completely destroys the tombs.

Seventh Doctor
Lilith visits the Doctor again. The TARDIS materialises in the English countryside near the village of Carbury, where a nuclear missile convoy under the command of UNIT's Brigadier Winifred Bambera has run into difficulties. Lying on the bed of the nearby Lake Vortigern is a spaceship from another dimension containing the body of King Arthur, supposedly held in suspended animation, and his sword Excalibur. Ancelyn, a knight from the other dimension, arrives on Earth to aid the King but is followed by his rival Mordred and the latter's mother, a powerful sorceress named Morgaine. They all recognise the Doctor as Merlin - a fact that the Time Lord attributes to events in his own future. A battle breaks out between UNIT and Morgaine's men. Brigadier Lethbridge-Stewart has come out of retirement to assist in the crisis and ends up using silver bullets to kill the Destroyer - an awesomely powerful creature unshackled by Morgaine to devour the world - although he himself is almost killed in the process. Morgaine tries to fire the nuclear missile but is overcome by shock when the Doctor tells her that Arthur is in fact dead. She and her son are then taken prisoner by UNIT.

Eighth Doctor
The Master is apparently exterminated by the Daleks on Skaro, and the Doctor agrees to take his remains back to Gallifrey in the TARDIS. The Master is not really dead, however, but has transformed into a shapeless morphant creature. He causes the TARDIS to make an emergency landing on Earth, in the city of San Francisco, in the year 1999. The Doctor emerges from the ship to find himself in the midst of a street battle between rival gangs. He sustains gunshot wounds and, accompanied by young gang member Chang Lee, is taken to hospital for emergency treatment. Surgeon Dr. Grace Holloway attempts to save his life but, failing to understand his alien physiology, actually causes his 'death'. The Doctor later regenerates into his eighth physical form. The Master has meanwhile taken over the body of an ambulance driver named Bruce. This is just a temporary measure until he can achieve his ultimate goal: to inhabit the Doctor's body. The Doctor manages to convince Grace that he is the same man that she thought had died on her operating table, and that he is an alien Time Lord - albeit half-human on his mother's side. Together, along with Lilith, they race against time to prevent the Master's scheme from bringing about the Earth's destruction at midnight on 31 December. They eventually succeed, and the Master is sucked into the Eye of Harmony within the TARDIS's cloister room. The Doctor bids farewell to Grace and Chang Lee - who ultimately saw the error of his ways - and departs in the TARDIS as the world celebrates the millennium. Lilith leaves her past father's TARDIS for the last time.

Ninth Doctor
The Doctor and Lilith find Rose Tyler trapped in the basement of a department store and save her before blowing up the building. Tracking the signal of a group of Autons, they find that Rose's boyfriend had been replace by an Auton. Lilith and the Doctor take Rose to the TARDIS and attempt to use Mickey's plastic head to locate the source of the signal. The head melts, but Rose realises that the transmitter must be the London Eye. The Doctor tries to negotiate with the Nestene Consciousness, but is overpowered by the Autons. Rose rescues him by dropping the anti-plastic into the vat where the Nestene Consciousness resided, killing it. After fleeing the underground complex, the Doctor and Lilith offer Rose more adventures with them. Though she initially refuses, she ends up joining the two when the Doctor explains that the TARDIS can also travel in time as well as space.

The Doctor and Lilith take Rose on her first adventure to the year five billion to view a cataclysmic event: the destruction of Earth. They're on an orbiting space platform with a group of invited guests. There are uninvited guests as well in the form of spider-like mechanical robots meant to sabotage the platform. The spiders soon dispose of the Steward and gain control of the platform's mainframe. The Doctor uncovers which guest brought along the robots, the bitchy trampoline Lady Cassandra. She teleports away, but the Doctor reverses the feed, bringing her back. Without the constant ability to moisturize what's left of her skin, Cassandra dies out and basically explodes. Going back to Earth for chips, the Doctor warns Rose that it's dangerous traveling with him, but she continues to travel with him and Lilith anyway.

Rose takes her first trip back in time as she, Lilith, and the Doctor travel to 1869 Cardiff. They take in a reading from none other than Charles Dickens but in the middle of the performance, a zombie-like creature interrupts the performance and there is a ghostly apparition. Rose is kidnapped and taken to the home of an undertaker where alien creatures are living in the gas lighting system and taken possession of the dead. Rose manages to get information from Gwyneth, the parlor maid, that points to her as the central point of contact for the alien beings. When things go south, Dickens figures out how to draw the Gelth from their hosts and Gwyneth ignites the house, destroying the aliens.

The Doctor, Lilith, and Rose return to present day London where Rose finds that she hasn't been away for the twelve hours she thought had gone by, but twelve months. Her mother had been searching for her frantically, having filed a report with the police and putting posters with her photo on every lamp post. To their amazement, an alien spacecraft crashes in the Thames and Earth has it's first contact with extra-terrestrial beings. The Prime Minister has vanished however and those in charge are not what they seem to be. Working with the only Member of Parliament who seems to be in London, Lilith, Rose, and the Doctor battle a race of alien beings, the Slitheen, who want to destroy the Earth and sell if off, piece by piece.

Now locked in the reinforced Cabinet Room, the Doctor, Rose, and Lilith finally learn of the Slitheen's intentions. Having locked themselves in however, how they will manage to stop them becomes a major issue. While trying to keep the aliens at bay, the Doctor works against the clock to destroy them the only way he knows how-- to blow up 10 Downing Street. To do so, Rose's boyfriend Mickey has to hack into a submarine's computer and launch a missile. The trio, along with Harriet Jones, manage to survive the carnage and walk away unscathed.

Lilith, the Doctor, and Rose travel to the year 2012 and land in a museum of extra-terrestrial objects accumulated by the very wealthy Henry van Statten. He's an avid collector but he's also using alien technology to develop new weapons from which he derives his large income. He's particularly proud of one device he's acquired but has not yet been able to make functional and to the Doctor's horror, it turns out to a very old and very dangerous enemy from the past. Rose accidentally sets the Dalek free and it goes on a rampage, killing almost everyone in the museum. But during that time, Rose's DNA was mutating it to the point where it could be persuaded not to kill. Rose points this out to the Doctor, who was preparing to shoot the Dalek, and he puts the gun down to let the Dalek commit suicide.

The Doctor, Rose, Lilith, and Adam travel two thousand years into the future and land on Satellite Five, a space station orbiting the Earth. From the moment they arrive, the Doctor feels that something is wrong but he can't quite put his finger on it. Satellite Five provides six hundred channels of news and information to everyone on Earth and the crew, all humans, have a chip implanted in them allowing their brains to work as computers. As they explore the station, the travelers learn of the mysterious Level five hundred that some of them are promoted to but are never seen again. The Doctor, Lilith, and Rose go to that mysterious level to find out just who-- or what-- is up there. Adam meanwhile tries to access the computer banks with the view to taking advanced knowledge back to present day Earth. Escaping the five hundredth floor, the Doctor takes Adam home and leaves him behind.

Rose asks the Doctor to take her back to the day her father died. Rather than just be with him when he dies, she actually saves him. By saving her father, Rose created a tear in space and time with the result that creatures are now feasting on humans and, eventually, the Doctor himself. Pete is able to set things right by allowing himself to be hit by the car that would've killed him before and the Doctor returned to existence.

Rose, Lilith, and the Doctor find themselves in 1941 London when the TARDIS receives an emergency signal from another time-traveling vehicle. Rose wanders off and the Doctor and Lilith meet Nancy, who has an interesting way of arranging meals for homeless children. They are also being chased by the child Rose heard calling. The Doctor determines that human DNA is being rewritten but it's not obvious why or by who.

Lilith, the Doctor, Rose, and Captain Jack Harkness are still in the hospital with the gas mask-wearing mutants and are having some trouble finding a way out. The Doctor determines that the ambulance Captain Jack was using in his scam contained nanogenes. Only in this case, there are enough nanogenes on the loose to "repair" an entire species and they have no idea what a human looks like in the first place. The future of the human race lies in Nancy accepting her true relationship to the little boy. In the end, everybody lives and Jack joins Lilith, the Doctor, and Rose on the TARDIS.

Six months after ridding London of the Slitheen, the Doctor takes the TARDIS to Cardiff to refuel on a rift in time and space. The Doctor, Rose, Lilith, and Jack are joined by Mickey. They've barely arrived when they realize that the new Lord Mayor is one of the Slitheen, Margaret, from their previous encounter. The nuclear facility she has been promoting is called Bad Wolf, an expression the Doctor and Lilith have come across on several occasions. The Doctor will transport Margaret to her home planet, where she says she faces a death warrant, but they are unable to depart until the next morning when the TARDIS is fully recharged. After unsuccessfully pleading her case to the Doctor, Margaret takes more decisive action by using the extrapolator to attempt to pull apart the TARDIS. In doing so, she inadvertently looks into the heart of the TARDIS and is regressed into an egg.

After delivering Margaret the Slitheen to her home planet, the Doctor, Rose, and Jack awaken to find themselves as part of TV reality or game shows. The Doctor is in the Big Brother house; Rose is a contestant on the Weakest Link; and Jack is on What Not to Wear (Lilith is still trapped on the TARDIS). The only difference is that if you lose on this show, your are 'eliminated'-- they take your life. The Doctor manages to escape and quickly realizes where they are: once again on Satellite Five, only this time one hundred years beyond their last visit. The Doctor realizes that something has gone very wrong with Earth's development and believes something far more sinister and complex is going on when he learns the satellite is now know as Bad Wolf TV. He, Lilith, and Jack race to find Rose but are too late. The Doctor realizes that he must once again face his greatest enemy, the Daleks.

The Doctor comes face to face with the Dalek Emperor but manages to rescue Rose. They return to Satellite Five to prepare for the invasion with Jack organizing the armed resistance and the Doctor and Lilith rewiring the station to produce a deadly Delta wave. The Doctor had always promised to take care of Rose and knowing that the Delta wave will destroy everything, he forces her to return to Earth on the TARDIS. Just as the Doctor decides that he can't use the Delta wave, Rose returns with the full force of the time vortex behind her. The Doctor takes the power away to prevent it from killing her, causing him to regenerate into his next body.

Rose Era
The newly regenerated Doctor travels to present day London and Rose is happy to be home. Her mother is happy to see her, her protestation to the contrary. The Doctor isn't well however suffering from what Lilith describes as regeneration sickness. While the Doctor is in a coma-like state, the people of the Earth are threatened by the Sycorax who threaten to destroy one-third of the planet's population if they don't surrender. When tea spills in the TARDIS, the resulting steam wakes the Doctor and he challenges the leader of the Sycorax to a sword fight for Earth. The Doctor wins and the Sycorax retreat, but Torchwood blows up the ship. He takes down Harriet Jones' Golden Age with six words and he, Lilith, Rose, Mickey, and Jackie return to the Powell Estate for Christmas dinner.

The Doctor, Lilith, and Rose set out on their first adventure since the Doctor regenerated. The Gallifreyans take Rose to see the Planet New Earth, colonized by the human race since the destruction of the original planet Earth. On arriving, the Doctor receives an invitation to visit a hospital run by the sisters of plenitude. A sisterhood of cat-women nuns who have the uncanny ability to cure so many long thought incurable diseases. But the Doctor and Lilith, along with a possessed Rose, discover there is a sinister method as to how the Sisterhood manage to develop such cures. The Doctor manages to cure the sick sub-species and Cassandra, who had been possessing Rose, dies for good.

The Doctor intends to take Rose and Lilith to a 1979 pop concert, but instead they arrive in Balmoral, Scotland in 1879. They have a chance meeting with Queen Victoria who is traveling with her entourage to the Torchwood estate, home of Lord Robert and his wife, Lady Isobel. Adopting the alias of Dr. James McCrimmon, the Doctor convinces the Queen that they are friends of the crown and are invited as guests of her majesty. An alien consciousness takes the form of a werewolf and has been passed down the centuries from person to person. It wants to take the royal throne and It's next intended host is Queen Victoria herself. The Doctor, Lilith, and Rose catch the werewolf in magnified beam of moonlight, destroying it. Queen Victoria knights the three of them, immediately banishing them afterwards.

Following the suspicions of Mickey; the Doctor, Lilith, and Rose go undercover as a school teacher, a teacher's assistant, and a lunch lady in a London high school. With the further help of Mickey, their investigations lead them to discover that the schools new headmaster, Mr. Finch, and his newly appointed members of staff are not of this Earth. The Doctor has finds an old friend and traveling companion from his past has crossed his path once again. Her name: Sarah Jane Smith. Sarah Jane strives to help the Doctor, Lilith, and their companions outwit Mr. Finch and the rest of the Krillitanes. Once the bat people had been dealt with, Mickey decides to join the TARDIS crew.

The Doctor, Lilith, Rose, and Mickey travel to what appears to be an abandoned space ship in the 51st century. The engines are functioning however and the power is being used to power a portal to 18th century Paris. There the Doctor and Lilith meet a young girl, Reinette, and save her from a creature under her bed. They sees again her after some years have passed and as a young woman, she is the future Madame de Pompadour. The Doctor soon realizes that the clockwork droids of the ship have been geared to track Reinette's activities at various points in her life waiting for her to be 'complete' so they can use her brain as the ship's computer. The Doctor smashes the last time window in order to save Reinette and Lilith uses her vortex manipulator to retrieve him from the 1700's.

The TARDIS falls through a gap in the time vortex which leads the crew to find themselves in a parallel version of London, England in the year 2006. It's a slightly more advanced era where Zeppelins fly overhead and the populace wear special ear pods where information can be downloaded via the Cybus corporation. Lumic is involved in his own personal business project which involves an alternate version of Pete Tyler, who has become a millionaire in this reality and who Rose is hell bent on meeting. When visiting the Tyler mansion, the Doctor and Lilith discover that Lumic now had invented an Earth version of Cybermen, which crash Jackie's party and kill the President, along with half of the guests, and corner the Doctor, Lilith, Rose, and Pete.

Lilith, the Doctor, and Rose, assisted by Pete and the Preachers, decide that the only way to stop the Cybermen is to infiltrate Lumic's factory and destroy it. Mickey and Jake Simmonds infiltrate Lumic's Zeppelin; Rose and Pete use fake earbuds to get into the factory with the crowd of controlled humans; and the Doctor, Lilith, and Mrs. Moore enter the factory through the cooling tunnels. A Cyberman kills Mrs. Moore and takes Lilith and the Doctor captive, along with Pete and Rose. The Doctor has a way to overload the Cybermen, by taking out the emotional inhibitor. The four escape in Lumic's Zeppelin, driven by Mickey, who elects to stay in the alternate universe.

Although aiming to land in New York City, the Doctor, Rose, and Lilith arrive in 1950s London on the eve of Queen Elizabeth's coronation. The girls and the Doctor see people being bundled into cars and driven away. Upon further investigation, they realize that a creature, the Wire, is feeding on peoples' brainwaves leaving them faceless and mindless. With the help of a teenager whose grandmother has been taken away, the Doctor and Lilith begin to uncover what is happening. Rose soon becomes one of the Wire's victims, infuriating the Doctor. He builds a contraption that will get rid of the Wire and takes it to the top of a TV tower where he traps the creature in a VCR tape. The Doctor is reunited with Rose, her face in place, and the two of them and Lilith stay for the celebration of the Queen's coronation.

Lilith, the Doctor, and Rose arrive on a planet that should not be there; it's orbiting a black hole. The answer seems to lie in a counterbalancing gravitational force emitted by the planet. The human scientists are there to study the phenomenon and are assisted by a subservient race of beings, known as the Ood. The surface of the planet is unstable and the TARDIS vanishes into a pit. It soon becomes clear that here is a creature of some sort is living in the pit and it can take control of the Ood. It uses the Ood to announce to the crew, the Doctor, Rose, and Lilith that 'the Beast is awake'.

The Ood are being controlled by 'the Beast', which describes itself as Satan and claims to be a being that has existed since before the creation of the known universe. The Doctor and Ida have descended ten miles into the bowels of the planet only to find themselves trapped there and unable to return to the surface. They find evidence of a ancient civilization and a seemingly bottomless pit where the doctor confronts the Beast and finds the solution. The only problem is that the solution may kill Rose. Lilith, who managed to use her vortex manipulator to join him, stood by the Doctor's side as he destroyed the thing keeping the planet in orbit. They find the TARDIS and are able to rescue Rose and the remaining crew, ignoring the fact that the Beast said that Rose would soon die in battle.

Finding Lilith packing a bag in her room, the young Time Lady admits her real identity. She is actually the Doctor's daughter from his personal future and was sent back to travel with him as that is what his future self had remembered happening. Lilith tells the Doctor that she is supposed to leave before the storm hits, but promises to come back eventually.

Martha Era
After about a year of traveling with Martha, the Family of Blood catches the Doctor's scent and he is forced to use the chameleon arch to hide himself as a human in the year 1913. While human, John Smith meets and becomes friends with the librarian of the school he works at, Adelyn Green. The two attend the town dance as friends, where the Family catches up with the Doctor. Adeline drops her pretense of being British, adopting an American accent and pulling out a 51st century blaster to kill one of the Family. When Timothy Latimer returns the fob watch containing the Doctor's consciousness, John is initially to stubborn to open it. Eventually he does, and saves Adelyn from the Family's ship. Adeline reveals herself to be Lilith, having regenerated since she left, and the Doctor introduces her to Martha with glee.

Weeping Angels sent the Doctor, Martha, and Lilith back to 1969 without the TARDIS and Lilith's vortex manipulator is broken. Luckily, at an earlier point, the Doctor had run into a woman called Sally Sparrow and she had given him a folder full of information on how to get back to 2007. Lilith needs to fix her vortex manipulator and return to stalk Sally while the Doctor and Martha stay in the 60's and make a video message for Sally with Billy Shipton. Sally succeeds in retrieving the TARDIS from the Weeping Angels and Lilith pilots the ship to 1969 to pick up Martha and the Doctor.

The Doctor, Lilith, and Martha arrive in present day Cardiff to refuel the TARDIS and are inexplicably thrust to a distant planet one hundred trillion years into the future. When they arrive they realize they have an unexpected passenger in Captain Jack Harkness who has been patiently waiting for the Doctor's return since the mid-19th century. On the planet they eventually meet Professor Yana who is running the thousand-year-old Utopia project, the aim of which is to relocate the humanoids creatures to a new planet, away from the outsiders who they fear they will become if they don't leave. When Professor Yana has need of someone to make repairs in a room in which no one can survive, the Doctor has the perfect candidate. While the Doctor was monitoring Jack in the radiation room, Lilith runs to him, panicking about Professor Yana really being the Master. The Master steals the TARDIS, leaving the Doctor, Jack, Lilith, and Martha behind.

With the Master having regenerated himself and taken the TARDIS, the Doctor, Martha, Lilith, and Jack manage to return to Earth. When they arrive, they see the new British Prime Minister, Harold Saxon, on television and Martha immediately recognizes his voice: it's the regenerated Master. He announces that he has been contacted by alien beings and that they will arrive in two days' time. Despite an attempt by the American President to take over the situation, the Master is very much in charge. The situation is particularly stressful for Martha in particular as the Master has taken her family as prisoners. On board the Valiant, the Doctor attempts to stop the Master, getting aged one hundred years in the process. He manages to get a telepathic message to Lilith and she and Martha use the former's vortex manipulator to disappear.

By the time a year has passed, the Doctor has figured out what the Toclafane are and it had all but broken his spirit. The Master ages him again as a warning to Martha and Lilith, causing the Doctor to show all nine hundred years of age. When the two girls are captured and taken on board the Valiant, they reveal the Doctor's plan to use the Archangel Network to restore himself and he stops the Master from detonating the black hole converters in the rockets meant to declare war on the rest of the universe. Jack destroys the paradox machine that the Master had used and resets time to a year prior. The Doctor looses his oldest friend when Lucy shoots and kills the Master for good. Jack declines the Doctor's offer to travel with him and Lilith again, and Martha decides that she's needed more on Earth, leaving the TARDIS.

Post-Martha Pre-Donna
Now traveling on their own, the Doctor and Lilith have something of a surprise when the TARDIS crashes into the Titanic. Only, this version of the famed ship is a luxury space liner. It's a Christmas-themed cruise with a visit to this strange planet called Earth. When some of the passengers travel down to the planet's surface, they find London deserted, owing to a series of alien attacks that in recent years always seem to occur at Christmas time. The Captain purposely lowers the ship's shield resulting in severe damage from asteroids. Joined by Astrid Peth, a waitress who Lilith has a crush on, and several passengers including Foon and Movin Von Hoff, Bannakaffalatta, Rickston Slade and Mr. Copper, the Doctor and Lilith fight robots in the form of angels. The angels have been tasked with killing everyone aboard and crashing the space liner into the Earth. The reason why is not obvious though the ship's owner, Max Capricorn, has his reasons. Astrid sacrifices herself in order to stop Capricorn and the Doctor manages to stop the Titanic from crashing into Buckingham Palace. Lilith, unable to save Astrid, joins the Doctor in returning to the TARDIS and the Doctor can't stop her from secluding herself for a month.

Donna Era
Tempting Lilith out of her self-induced solitude, the Doctor investigates Adipose Industries who claim to have created a revolutionary diet pill. The head of Adipose, Miss Foster, runs a tight ship and they have been quite successful. Lilith and the Doctor visit several people who have taken the pills and as advertised, the pills seem to be working. Sneaking back into the company's building, duo runs into and joins forces with Donna Noble, the bride who had been dosed with Huon particles. As a group, they discover that the human race is being used to breed Adipose since their breeding planet, Adipose III, had been lost. When the nursery ship arrives, the Doctor fails to save Matron Cofelia. He invites Donna to travel with him and Lilith as a friend, and they pilot the TARDIS so that Donna can eave goodbye to her grandfather.

The Doctor, Lilith, and Donna land in the marketplace in Pompeii in 79 A.D., the day before the big eruption and the destruction of the city. The Doctor's destination was actually Rome but he soon realizes his mistake...but not before a market vendor sells the TARDIS to a local businessman, a seller of marble whose daughter may be able to predict the future. Donna sees an opportunity to warn everyone and evacuate the city but the Doctor flatly refuses. When the Doctor learns that those with the ability to see future are slowly turning to stone, he finds out that alien beings are operating inside the volcano. Once in the aliens' escape pod, he realizes that they are draining the volcano's 'power' and that Vesuvius isn't going to erupt. But since it has to, being a fixed point in time, that means that he is the one who causes the eruption, essentially killing the entirety of Pompeii. Lilith refuses to let the Doctor have their deaths on his conscious and sets off the explosion, causing the volcano to erupt. When they got back to the TARDIS, before the Doctor could dematerialize, Donna and Lilith convince him to save just one family.

''One year later, the family is settled in Rome. Lilith's fourth incarnation watches them from the shadows, her father having recently regenerated into looking like Caecilius.''

Donna is terrified at her first off-world trip where she, Lilith, and the Doctor encounter the Ood. It's the year 4126 and they seem to have arrived at factory where the Ood are prepared for sale to anyone willing to pay the price. The Ood from all appearances are a subservient race and are fitted with a communications device. Some of them however seem to be going rabid with their eyes turning a bright red, like they had at the sanctuary base on Krop-Tor. The Doctor, Donna, and Lilith investigate, finding out that the Ood are actually born with a hind-brain that the company cuts off to stitch on the translator. Furious, the three allow themselves to be captured and taken to the CEO of Ood Operations who is planning on killing all of the Ood. Once they escape, Ood Sigma takes them to the Ood Brain. The CEO gets turned into an Ood and the Doctor defuses the bombs meant to take out the Brain. The Ood return the Doctor, Lilith, and Donna to the TARDIS, saying that the Ood will sing songs of Lilith and the DoctorDonna and that the Doctor's song will be ending soon.

The Doctor gets a call from former companion Martha Jones with a request that he return to Earth immediately. UNIT has taken over the ATMOS factory and she needs his help after fifty two people around the world all died simultaneously. All had the ATMOS anti-pollution device fitted on their cars so the military has raided the factory believing it to be controlled by aliens. The Doctor decides to pay a visit to the inventor of ATMOS. Donna meanwhile misses her family and decides to pay them a visit. Lilith and the Doctor discover that the Sontarans are behind the ATMOS device and plan to attack the Earth.

The Sontarans launch the attack with their poison gas slowly encircling the planet. They've also taken the TARDIS to its headquarters, but don't realize that Donna is inside. The Doctor and Lilith find that the Sontarans have cloned Martha. The Doctor knows that fighting the Sontarans is of little use as they never surrender and are prepared to fight until they win. He tries to convince Colonel Mace of that, but UNIT doesn't listen. After saving Martha, the Doctor decides to try and burn the poison gas that now covers Earth. He needs to destroy the Sontaran ship as well, but knows that, in doing so, he would have to sacrifice himself. Lilith figures out his plan and stuns him, taking it upon herself to destroy the Sontarans. Luke Rattigan takes her place and Earth is saved. The Doctor, Lilith, Donna, and Martha return to the TARDIS, which takes off on her own before Martha can leave.

Martha doesn't have time to leave the TARDIS when it is whisked away to a distant planet by forces beyond the Doctor's control. When they arrive they find two civilizations that seemingly have been at war with one another for generations. Both have the ability to create clones and the humans use the Doctor to create Jenny who is, effectively, the Doctor's daughter. Lilith, knowing Jenny from her past, is fiercely protective of her when the Doctor refuses to accept Jenny. The Doctor, Lilith, and Donna find themselves trapped with the humans after a tunnel cave-in. Martha however is taken by the other group, the Hath. The Doctor and Lilith continue to learn more about the human-Hath war and about its origins. They find out that it started over something called the Source and eventually discover that the war had only been going on for a week. The Source turns out to be a terraforming sphere, which the Doctor activates. One of the humans tries to shoot him, but Jenny gets in the way and dies without regenerating. Lilith insists on waiting five and a half hours, as that is what the Tyler-Lungbarrow family does, and later joins the Doctor, Martha, and Donna on the TARDIS, saying that Jenny traveling with them wasn't meant to be.

The Doctor, Lilith, and Donna arrive at an English country estate in the 1920s and meet none other than the renowned murder mystery writer Agatha Christie. The Doctor also realizes the importance of the date-- it's the day when Christie famously disappeared for ten days, creating headlines across the country and around the world. History records that she reappeared ten days later claiming to have no memory of where she has been or what she has done. They no sooner arrive than there is a murder, which Donna can't help but find it amusing since the victim is Professor Peach who was killed in the library with a lead pipe. In true Agatha Christie's fashion, the solution to the murder is found in a false identity and events that occurred long ago. After helping them, the Doctor and Lilith drop Agatha off ten days later.

The Doctor, Donna, and Lilith land in the 51st century to visit the greatest library in the universe. The Doctor is somewhat taken aback however to find there is no one there. To the best he can determine, the Library has been closed for one hundred years so the arrival of a team of archaeologists comes as something of a surprise. The private expedition has been paid for by a wealthy amateur but the expert leader of the group is, much to Lilith's surprise, her Aunt River Song. Although the Doctor doesn't know her, it soon becomes apparent that she knows him quite well having met him in another time. All of them however come into danger when they make contact with a young girl who communicates with them through her television. The encounter has consequences for Donna in particular who seems to have been absorbed into the Library.

In the Library itself, the Doctor, Lilith, and River try to find out what happened, not only to Donna, but to the over four thousand people the computer says were saved when the library was shut down a century years ago. After the Vashta Nerada manage to kill everyone but the Doctor, River, Lilith, and Mr. Lux, the Doctor realizes that it has to do with CAL and the only way to save all four thousand and twenty three people is for him to sacrifice himself. He sends Lilith and River away only to have them return and knock him out. When he wakes, River has herself strapped in, ready to be used to release the people held in the computer. The Doctor protests, saying that time can be rewritten, but River refuses. The countdown reaches zero, killing her. Lilith and the Doctor are reunited with Donna and Lilith retreats into the TARDIS without the other two. The Doctor suddenly understands why his future self gave River a screwdriver and uploads her to the mainframe, 'saving' her.

Lilith, the Doctor, and Donna are taking a bit of a break from their adventures and spending a bit of time on the planet Midnight. While Donna and Lilith opt to spend a bit of time in the spa, the Doctor goes off on an all-day bus tour to the Sapphire Waterfall. Part way through the four hour journey to get there, the vehicle stops for no apparent reason. When they hear noise coming from outside the vehicle, panic begins to set in. When one of the passengers is taken over by the being, the passengers paranoia and fear know no bounds and the focus of their solution is to eliminate the Doctor. Lilith, having sensed that the Doctor was in danger, appeared on the bus and gets rid of the creature, saving the humans and the Doctor.

Donna, Lilith, and the Doctor are having fun at a market on a distant planet when Donna is lured to a tent with the promise of having her fortune told. A parallel universe was created, where Donna and Lilith, who went by Echo, met a blonde woman who told Donna to give the Doctor a message. Two words: Bad Wolf. Panicked, the Doctor and Lilith see the words written on everything throughout the market. Inside the TARDIS, the cloister bell is ringing and Donna asks what Bad Wolf is. The Doctor answers, "It's the end of the universe."

The universe is beginning to crumble, and the Earth is pulled out of its orbit around the Sun and finds itself grouped with 26 other planets in a far off location. When the enemy is revealed to be the Daleks, everyone expects the worst, particularly when their leader is revealed to be someone from the Doctor's distant past. landing on Earth, the Doctor finds himself reunited with Rose Tyler, but before he can reach her, he gets shot by a Dalek. Jack Harkness, Rose, Lilith, and Donna drag the fatally wounded Doctor back into the TARDIS and he starts to regenerate.

Funneling the regeneration energy into his spare hand, the Doctor emergedsfrom the regeneration in the same body. Rose reveals that the universes are being destroyed, and an analysis of timelines shows that everything revolves around Donna. The Daleks have the power to break into the TARDIS, so the companions voluntarily leave it. But the door slams shut before Donna can come out, and the Daleks attempt to destroy the ship by sending it and her into the core of the Crucible. In the vault, Martha contacts the Daleks, threatening to activate the Osterhagen key. At the same time, Jack and Sarah Jane devise a plan to destroy the Crucible. They also threaten the Daleks. Davros points out that the companions all have devised weapons to attack the Daleks, against the Doctor's code of nonviolence, and the Daleks teleport all the companions to the Crucible. The ignition sequence of the bomb begins. A second Doctor returns in the TARDIS and attempts to shoot down Davros. He fails, and Donna does not how to work the gun, but Davros blasts her with an energy beam. The energy wakens a new part of Donna-- when the second Doctor became part-human, Donna also became part Time Lord. She shuts down the bomb and takes control of the Daleks. The Metacrisis completes Dalek Caan's prophecy by killing all of the Daleks and the entire group of companions and Doctors flee in the TARDIS. When Earth is back in its proper place, Sarah Jane, Jack, Martha, and Mickey all leave the TARDIS. Lilith tells the Doctor that he'll see her two more times and hugs the Doctor goodbye, leaving as well.

More Timey-Wimeyness
Investigating aliens in 1562, the Doctor has proposed the Queen Elizabeth I in an attempt to prove her a Zygon. The proposal is followed by a false accusation, running, and the Zygon turning into Elizabeth. A time fissure opens and out falls the Eleventh Doctor. To make things worse, the Doctor's Warrior incarnation appears as well, followed by, to the Eleventh and Tenth Doctors' surprise, Lilith. The four of them got thrown in the Tower of London where they were eventually sort of rescued by Clara, then let out by Elizabeth. She explained the Zygons' plan to invade Earth in 2013. The Doctors agreed to help stop the invasion, but the Tenth Doctor said he needed his TARDIS. Elizabeth had it ready for him be reminded the Doctor that he had a promise to keep. The proposal. The Tenth Doctor married Elizabeth, promised he'd be right back, and fled into the TARDIS. The three Doctors, Lilith, and Clara returned to 2013 to stop the invasion by helping Kate Lethbridge-Stewart negotiate a peace treaty with the Zygons. After Lilith and the War Doctor returned to Gallifrey, the Eleventh, Tenth, and Clara follow. The two older Doctor's offer to detonate the Moment with the War Doctor, but Clara convinces her Doctor not to and the three, along with Lilith, come up with a plan to save Gallifrey by freezing it in an instant of time. After the plan was implemented, the five sat in the under gallery. The War Doctor leaves in his TARDIS, and the Tenth questions Lilith about her mother and the Eleventh about where they were going. The Eleventh Doctor tells him about Trenzalore and the Tenth Doctor heads to his TARDIS saying that he doesn't want to go.

Rose Returns
The Doctor, having been alone for decades, is hiding in the Gallifrey room when Lilith appears for the last time. She exlplains to him the details of the time loops and gives him the last of the information he needs to make sure things go as her linear father remembered. She also tells him about the time loops she closed after leaving the Medusa Cascade and that once she was done with that, she went and "picked up her mother." When the Doctor asks what she means, he hears Rose Tyler speak from the doorway. He runs over to greet her and when he tells her he loves her, she kisses him.

Tenth Doctor
When the Doctor and Rose's second daughter, Darkelvoriplorellion, is five years old, the Doctor decides that it's time to stop running from Ood Sigma and takes his family to the Ood Sphere. There he learns that the Master will return, heralding the end of time itself. Hiding Lilith and Darkel in the TARDIS, the Doctor and Rose attempt to trace the Master and encounter Wilfred Mott on Christmas Eve. The Doctor tracks the Master to wastelands outside London. Before the Doctor could get through to him, the Master is abducted by troops and placed in the custody of billionaire Joshua Naismith. The Doctor and Rose, along with Wilf, travel to the Naismith estate where they discover that the billionaire is in possession of an alien Immortality Gate and has enlisted the Master to fix its programming. Two Vinvocci attempt to explain that the device is simply for medical use, but are unsuccessful. The Master ends up using the device to replace all humans with copies of himself. The Master and his doppelgangers taunt the Doctor, who can only look on in horror.

The Doctor, Rose, and Wilf are rescued from the Master by the Vinvocci, taking refuge on their orbiting ship. Gallifrey materialises above Earth, and all the other horrors of the Time War are likely to follow. The Doctor, armed with Wilf's gun, breaks into the room from above by jumping from the Vinvocci ship, but wavers between killing the Master or the President in order to sever the link. He spots the whitepoint star and shoots it instead. As the Time Lords are drawn back into the Time Lock, the President attempts to kill the Doctor but the Master intervenes, sacrificing himself in an act of revenge against Rassilon for the endless drum beat he placed in his head. In a flash of light, the Time Lords, the Master, and Gallifrey all disappear. Taking a moment to realise his victory, the Doctor hears four knocks, the sound which he has been told will precede his death. He finds Wilf, having returned with Rose to help the Doctor, still trapped in the Gate's isolation chamber that will be flooded with radiation due to the Master's modifications; only the self-sacrifice of another will free him. The Doctor releases Wilf, collapsing in agony as he receives a massive dose of radiation. Although he survives initially as his body absorbs the radiation, the healing of the Doctor's wounds shows his regeneration process has begun.

After taking Wilf home, the Doctor, Rose, Lilith, and Darkel visit past companions. Companions Martha Jones-Smith and Mickey Smith, Darkel's godparents, are working as freelance alien hunters; the Doctor saves them from a Sontaran sniper. Rose rescues Luke Smith from an oncoming car, and silently acknowledges Luke's mother, former companion Sarah Jane Smith. At an extraterrestrial bar, the Doctor passes a note to a despondent Jack Harkness, encouraging him to start a conversation with Alonso Frame, seated next to him. They then land the TARDIS in a lane opposite the church where Donna's wedding has just taken place. The Doctor and Rose give Wilf and Sylvia Noble a lottery ticket that the Doctor had bought for Donna with money borrowed from her deceased father, to assure their financial future. Wilf, misty-eyed, salutes the Doctor for the last time as he leaves. They return to the TARDIS and Rose holds Lilith and Darkel back as the regeneration starts in earnest. The Doctor cries, "I don't want to go", and the violent energy his body releases as he regenerates shatters the TARDIS windows and sets the console room ablaze, nearly killing the three girls.

Pond Era
With his regeneration complete, and the rest of the Tyler-Lungbarrows alive, the Eleventh Doctor inspects his new body before realizing that he and his family are in danger. He shouts, "Geronimo!" as the TARDIS' console crashes and explodes while hurtling back to Earth. While Lilith kept Darkel safe, Rose and the Doctor manage to (crash) land the TARDIS in Leadworth, 1996. The Doctor and Rose left the two girls in the TARDIS while meeting young Amelia Pond. Amelia shows the two the crack in her wall and the Doctor discovered that it is a crack in space and time itself. It briefly opens, showing an Atraxi prison, and the jailor send the Doctor the message, 'Prisoner Zero has escaped'. He and Rose have to rush back to the TARDIS when the cloister bell starts ringing, promising Amelia that they'd be back in five minutes. Lilith tries to help fix the issue, but smoke begins to fill the console room. The TARDIS is able to hide Darkel from the danger, but Lilith leaves the TARDIS with Rose and the Doctor to warn Amelia that prisoner Zero is in her house.

Upon searching the house, they find a policewoman instead who turns out to be Amelia, now Amy, just twelve years older. The Doctor then reveals to Amy that Prisoner Zero has been hiding in a room in her house that she had never noticed, due to a perception filter. After venturing into the room, she frees the Doctor and grants him his sonic screwdriver. They dodge an attack by Prisoner Zero and flee the house. Shortly afterwards, the Atraxi arrive in orbit, alerted by the Doctor's arrival, and issue an ultimatum: if Prisoner Zero does not vacate 'the human residence', meaning the Earth, they will incinerate the planeta. Meeting Amy's boyfriend Rory Williams, the Doctor realises that Prisoner Zero, a multiform that can take the form of any unconscious being by forming a telepathic link with them, is borrowing the forms of a nearby hospital's coma patients. The Doctor and Rose use a laptop to gatecrash an online meeting of scientific experts discussing the Atraxi situation and send instructions to them while Lilith goes with Amy and Rory to the hospital.

The Doctor and Rose race to the hospital, just in time to save Amy, Lilith, and Rory from Prisoner Zero. The Doctor reveals his plan: he has created a computer virus that will broadcast the number zero across the world. It is tied to Rory's phone, which contains images of the coma patients, identifying Prisoner Zero in whatever form it may take. Prisoner Zero reveals it has one more form, knocks out Amy, and transforms into the Doctor, Rose, and young Amelia. The Doctor realises that Amy can hear him speaking and manipulates her subconscious to remember the form of Prisoner Zero she had seen in her house. This forces Prisoner Zero to revert to his true form; it is identified by the Atraxi and captured. Before being transported away, Prisoner Zero warns the Doctor that "Silence will fall." The Atraxi fleet leaves, but the Doctor, invoking the Shadow Proclamation, orders their return and reprimands them for threatening the planet. The Doctor shows the Atraxi images of the many past alien invaders who have attempted to seize or destroy the Earth, but who have been defeated by his past incarnations, causing the Atraxi to take him at his word, and run. The Doctor, Rose, and Lilith return to the TARDIS and depart before Amy or Rory can catch up. The Doctor later returns to Amy's house, finding that another two years have passed. Though still upset, she readily accepts their offer to travel together, as long as they can return her the next day.

After dropping Darkel off with her godparents, the Doctor, Rose, Lilith, and Amy arrive on the Starship UK in the distant future, a colony spaceship containing the population of the United Kingdom who have left the planet to escape deadly solar flares. They come across a crying girl, Mandy, whom all the other adults aboard consciously ignore. The Doctor, having discovered that the ship does not seem to be powered by normal engines, tells Amy and Lilith to follow Mandy while he and Rose explore the engine room. There, they find the engine controls to be a false front, and encounters a masked woman called Liz 10, who also is aware of the ship's oddness and of the Doctor's identity. The Doctor and Rose arrive at the voting booth; Mandy explains that the voting takes place every five years and everyone chooses to forget. The Doctor, however, triggers the protest sequence, sending him, Lilith, Rose, and Amy into the bowels of the ship. Finding themselves in the mouth of a giant creature, the Doctor uses his sonic screwdriver to make the creature throw them up. Liz 10 reveals herself to be Queen Elizabeth X.

The Winders arrive and take Liz 10, the four travelers, and Mandy to the Tower of London, where it is revealed that all of Starship UK rides atop a giant Star Whale that provides the ship's locomotion. However, in order to direct the whale, the pain center of its brain has been exposed to receive frequent jolts of electricity. The Winders show Liz 10 that she ordered this centuries ago, but every ten years she finds her way to the Tower and chooses to have her memory wiped to prevent herself from remembering. The Doctor is furious, realising to his despair that he has to choose between saving the humans or the Star Whale. He decides to alter the controlling device programming to render the Star Whale brain-dead, allowing it to continue through space but no longer feel the pain. As the Doctor worked, Amy, considering all she has seen and heard, takes control and uses Liz 10's hand to strike the abdicate button that disables the controlling device and allows the Star Whale to break free. To everyone's surprise, the Whale does not leave, and in fact the ship moves faster. Amy explains to the Doctor that she saw the similarities between him and the Star Whale, and deduced that the Whale came to Earth willingly at the time of crisis. She and the Doctor reconcile, and they all return to the TARDIS.

The Doctor and Rose pilot the TARDIS to the Cabinet War Rooms during The Blitz of the World War II, one month after Winston Churchill requested the Doctor's help in the war effort. As they arrived late, Churchill turned to the scientific advances of Professor Edwin Bracewell, including robotic devices called "Ironsides", which are recognised immediately by the Doctor and Rose as Daleks. After sending Lilith back to the TARDIS, the Doctor tries to understand their purpose in being on Earth at this time, but they continue to act as Bracewell's inventions, ready to serve Britain's war efforts. Angrily, the Doctor attacks the devices, shouting, "I am the Doctor and you are the Daleks!" Upon hearing the Doctor's 'testimony', the Dalek aboard the orbiting ship uses it to activate a Progenator Device and alerts its comrades on Earth. The Daleks reveal their intent and turn hostile, killing several guards and exposing Bracewell as an android before transmatting to their ship. The Doctor and Rose follow in the TARDIS, leaving Amy behind for her protection. The Doctor learns that the ship escaped destruction at the Game Station after it fell through time by accident, leaving it nearly drained of power. The Daleks' objective is to restart the Progenator, which contains pure Dalek DNA, thus restoring their race. Since these particular Daleks were created from humans, the Progenator could not properly accept them as Daleks, and so they required a testimony from their greatest enemy to activate it. The Doctor threatens to destroy the ship, including himself and Rose, before the Progenitor completes, but the Daleks fire an energy beam at London that lights up the entire city minutes before an air raid by the Luftwaffe, leaving the Doctor's allies vulnerable and creating a stalemate.

When the Progenator completes, five brand new Daleks in larger, redesigned casings emerge from the Progenator Chamber. They disintegrate the older, 'inferior' models, who die willingly. At the same time, Amy convinces Churchill and Bracewell to use the technological know-how they have obtained from the Daleks to modify three Spitfires so that they can fly in space. The pilots attack and destroy the dish on the underside of the Dalek ship that was firing the energy beam, saving London before it can be destroyed by the approaching German bombers. The Doctor orders the last Spitfire pilot to continue his attack and destroy the Dalek ship, hoping to rid the universe of them forever. The Daleks retaliate by triggering the Oblivion Continuum, the power source inside Bracewell that contains an unstable wormhole that will consume the planet if released. The Doctor, torn over defeating the Daleks or saving Earth, orders the Spitfire to stop its attack and returns to Earth. With Amy and Rose's help, the Doctor is able to convince Bracewell that he is more human than machine, deactivating the device. The Daleks announce their victory and retreat into hyperspace. The Doctor and Rose remove all the advanced technology borrowed from the Daleks despite Churchill wanting to use it for the war, and convince Bracewell that he need not be deactivated because he helped save the world. As they leave, the two ponder why Amy does not remember the Daleks from their previous invasions of the Earth.

The Doctor, Rose, Lilith, and Amy travel to the Delirium Archive, a museum in the distant future and discover a message from River Song, engraved in Old High Gallifreyan, the language of the Doctor's home planet, on a damaged flight recorderfrom the starship Byzantium twelve thousand years in the relative past. The Doctor and Rose take the TARDIS to rescue her before the ship crashes on the planet Alfava Metraxis. After the TARDIS lands on the planet via River's guidance, Amy learns from both the Doctor and River that they have a unique relationship owing to the nature of time travel; she has met the Doctor numerous times before in her timestream, while he still barely knows who River is. The Doctor introduces River to Lilith as 'Aunt River', as that is what her third incarnation called River at the Library. River warns them that the Byzantium 's cargo hold contains a deadly Weeping Angel, which can move only when unobserved by others. She calls down the orbiting Father Octavian and his militarized clerics to help her capture the Angel before the radiation leaked from the ship makes it too powerful, and to protect a large human colony on the planet. River, the Doctor, Lilith, Rose, and Amy review a four-second loop of security footage of the Angel in the Byzantium vault as the soldiers set up base camp. Outside the trailer, the Tyler-Lungbarrows and River look through a book written by a madman about the Angels and find the words, "That which holds the image of an Angel becomes itself an Angel".

Amy has returned to the viewing room; each time she turns away the Angel from the footage moves and it begins to emerge from the screen, trapping her in the room. The Doctor, Rose, and River attempt to free Amy; the Doctor warning her not to look directly into the eyes of the Angel because the book compared eyes to the doors of the soul. Amy is able to turn off the image on a loop break, causing the Angel to disappear and saving herself. To access the Byzantium and locate the Angel, the group must travel through a Maze of the Dead, a stone labyrinth with numerous statues erected by the native race, among which the Angel could easily hide. After launching a gravity globe near the roof of the Maze to provide illumination, the group splits up, with some soldiers left to guard the entrance. While the Doctor, Rose, and River discuss the two-headed natives who built the catacombs, it suddenly occurs to them that all the statues have only one head: they must therefore be Weeping Angels. Each of these is slower and weaker than the Byzantium's captured Angel, having had no beings to consume over the centuries, but they are now absorbing energy from the crashed ship; the Doctor surmises that the Angel purposely crashed the Byzantium to rescue its kind. The group soon finds that the Angels have killed their rear guard and are using the consciousness of one soldier, Bob, to speak to the Doctor. The Angels reveal they have lured the group to the highest point of the maze, directly under the crashed ship, and are planning to kill and use their essences to further regenerate. The Doctor tells the Angels that they should have never put him or his family in the trap, and prepares the group to jump once he destroys the gravity globe.

The destruction of the gravity globe allows the Doctor, Rose, Amy, Lilith, River, and Father Octavian and his clerics to jump into the localized gravity well of the starship Byzantium and escape the horde of approaching Weeping Angels. The Angels follow them into the ship and the Doctor directs everyone into the ship's oxygen factory, a forest contained within the starship. While in the secondary control room, the Doctor observes a crack in the wall and realizes that it is the same one from Amy's bedroom. He determines that it is leaking time energy from which the Angels are attempting to feed. In the forest, the Doctor, Lilith, Rose, and River find Amy struggling with an image of an Angel imprinted in her brain. Amy has been counting down backwards and is close to being killed by the Angel when the Doctor instructs her to keep her eyes closed to starve the angel. With Amy unable to move, the others and Octavian attempt to reach the primary control room on the other side of the forest. Octavian reveals to the Doctor and Rose that River is a prisoner in his custody, with a pardon promised should she help them complete their mission.

Octavian is captured and killed by an Angel as the others enter the control room. The Doctor contacts and instructs Amy to begin moving towards the primary control room, keeping her eyes closed but acting as if she is still able to see in order to fool the Angels. She trips and reveals her blindness to the Angels, but before they can kill her River teleports her to the control room. The Doctor reveals that the crack is due to an explosion somewhere in time, a date that he, Rose, and River are able to determine. The Doctor warns that anything that falls into it is erased from time; this is why the Angels fear the crack. The only way of temporarily closing the crack is to send a complicated space-time event, such as the Doctor himself or the whole of the Angels, into the crack. The Angels continue to drain power from the Byzantium until they cause the artificial gravity to fail, dropping the Angels into the crack and sealing it while the Doctor, Amy, Lilith, Rose, and River hang on to the controls. With the Angels gone, the Angel in Amy's mind never existed, and she is able to recover. River is teleported away by the clerics; she tells the Doctor, Rose, and Lilith that they will meet again soon when the "Pandorica" opens, which is dismissed by the Doctor as a fairy tale.

The Doctor, worrying that the travel would destroy Amy's relationship, gatecrashes her fiancé Rory's stag party and invites the two of them on a romantic trip courtesy of the TARDIS. They land in Venice in 1580 and soon find trouble. The city's patron, Signora Rosanna Calvierri, claims that the Black Plague runs rampant outside of Venice. The Doctor says this is false and that it appears she is using the plague as an excuse to seal off the city. While investigating, they encounter Guido, a boat-builder whose daughter Isabella hasn't contacted him since enrolling in Signora Calvierri's school for girls. Amy and Lilith devise a plan to place themselves inside the school with the help of Rory and the psychic paper. They manage to unlock a gate and allow the others in, but in doing so are captured and taken to a chamber. The Doctor, Rose, and Rory come to believe the women are being converted into vampires, and discover a box containing a dead figure. The 'vampires' begin converting Amy into one of them when Isabella frees Amy and Lilith and they escape. Isabella hesitates while escaping because she can no longer tolerate direct sunlight and is pulled back inside while the door closes. The Doctor tries to open the door but he gets shocked by electricity and collapses.

The Doctor and Rose go back inside to question Signora Calvierri who confirms that she and the others are from the planet Saturnyne, a race of aquatic beings with vampire-like tendencies. She and the others landed on Earth after seeing the cracks in the universe. Calvierri and her son Francesco intend to sink the city into the water and convert humans into 'Sisters of the Water' in order to continue their race. When they returns to Guido's home to regroup with Lilith, Amy, and Rory, Signora Calvierri sends her transformed girls to attack them. Guido sacrifices himself for the others by blowing up several kegs of gunpowder that kill him and the girls. Signora Calvierri activates a device on a tower that begins to create the earthquakes and floods that will sink Venice. While Amy, Rory, and Lilith face and defeat Francesco, the Doctor climbs the tower and stops the device in time. The last of her kind, Signora Calvierri throws herself into the canal to be eaten, but not before tormenting the Doctor by reminding him that he is now responsible for the extinction of two species: her own, and the Time Lords. In the aftermath of the incident, the travelers invite Rory to continue traveling with them, but as the Doctor and Rory are about to enter the TARDIS, everything falls silent. Unnerved, the Doctor remembers Signora Calvierri's words: "We saw silence, and the end of all things..."

The Doctor, Lilith, Rose, Amy, and Rory find themselves flickering between two realities, falling asleep at the sound of birdsong in one and waking in the other. In the first reality, Amy and Rory stopped travelling with the Tyler-Lungbarrows five years previously, are happily married, and Amy is heavily pregnant. They find themselves in their hometown of Leadworth being chased by the Eknodine, an alien race that have disguised themselves as the elderly of the town. The Eknodine are able to turn anyone into dust by blowing a poisonous liquid on them. In the other reality, they are trapped in the powerless TARDIS drifting towards a freezing cold star which will kill them. During one of their experiences in the TARDIS-reality they are met by the Dream Lord, an apparition who tells them that he has created a dream reality in contrast to their actual reality. The four must determine which is the dream reality and kill themselves in it to return to the other reality. However, if they choose wrong they will be killed in both.

The Doctor and Rose are trying to rescue people from Leadworth in a motor-caravan. As Amy believes she is going into labour, Rory and Lilith are sprayed by the Eknodine and turn to dust. Amy decides that she is willing to risk her own life for the chance of seeing Rory again, and Rose to see Lilith, and they conclude the Leadworth reality is false. Amy, Rose, and the Doctor drive the motor-caravan into the house, leading to their assumed deaths. The five wake up again on the TARDIS where they are congratulated by the Dream Lord, who then reactivates the TARDIS. After the Dream Lord's departure Amy and Rory are surprised by the Doctor when he directs the TARDIS to self-destruct, apparently killing them all. They wake up again on the TARDIS, no longer in any danger. The Doctor realizes both realities were false since the Dream Lord had no power over the real world and was a manifestation of his darker side. They were influenced by psychic pollen that had fallen in the TARDIS time rotor and heated up, creating the Dream Lord and the false realities.

Lilith, Rose, the Doctor, Amy, and Rory land in the small Welsh village of Cwmtaff in 2020 instead of their intended destination, Rio de Janeiro. They encounter a mining operation led by Doctor Nasreen Chaudhry, who is studying minerals deep in the earth that have not been seen for over twenty million years. Nasreen is assisted by a local, Tony Mack, whose daughter and grandson, Ambrose and Elliot, are investigating the disappearance of bodies at the nearby church graveyard. An earth tremor causes the ground to open and sends Tony, Rose, and Amy falling into it; Tony is rescued but Amy and Rose are pulled under by unknown forces. The Doctor surmises that the minerals form a bio-reactive defence system triggered by the drilling operation. The group is soon alerted to the presence of three life forms travelling up the drilling shaft from 21 kilometers below the earth, and they barricade themselves in the church. The Doctor explains Rose and Amy's disappearance to Rory and Lilith, and assures them he will get them back.

The three beings are discovered to be reptilian humanoids, and in a scuffle, they capture Elliot and strike Tony with a venomous forked tongue; the Doctor, Lilith, and Rory subdue one while the other two retreat with Elliot back into the earth. The Doctor realizes the beings are a new form of Silurians, and that they have relented in their attack since both sides hold a hostage. The captured Silurian calls herself Alaya; she is a member of the warrior caste, awoken by the drill. Alaya believes, as do all Silurians, that the Earth still belongs to them, that the drilling was a form of attack by the humans, and that they will defeat humanity eventually. Tony, suffering from the effects of the venom, says they should dissect Alaya, but the Doctor warns that it would be seen as an act of war. The Doctor decides to travel in the TARDIS down the drilling shaft to talk to the rest of the Silurians and work out a truce; Nasreen and Lilith accompany him. They arrive underground in the TARDIS; the Doctor explains about the Silurians and says that he expects to encounter only a few of the creatures. Instead, they find an immense Silurian civilisation in the caverns below the earth.

As the Doctor, Lilith, and Nasreen arrive in the massive Silurian underground civilisation, they are captured and taken to the Silurian doctor, Malohkeh. The Silurians' hostility is increased when the Doctor recalls his previous meeting with a similar race of reptilian humanoids which were destroyed by humans. When Malokeh realizes the Doctor and Lilith are not human, the leader of the Silurian warrior caste, Restac, insists both the Doctor and Lilith and Nasreen be executed and escorts them to a Silurian court; though Amy, Rose, and Mo interrupt the trial with stolen weapons, they too are captured. Eldane, Restac's superior, is called in by Malohkeh and demands a halt to the hostilities. The Doctor makes contact with Rory, Mo's wife Ambrose, and Ambrose's father Tony, reminding them to keep their captive Silurian, Restac's sister Alaya, alive. The Doctor arranges a conference between the Silurians, represented by Eldane, and the humans, represented by Amy and Nasreen; the three discuss how both species can co-exist on the surface of the Earth.

When Rory and the others arrive with Alaya's corpse, Restac becomes furious and orders the humans' death; the Doctor disables their weapons to give him, Eldane, and the humans time to escape; they bar themselves into Malohkeh's lab. The Doctor and Eldane realise they can use Silurian technology to destroy the drill before it detonates, but it will cause their exit route to collapse if they cannot reach the TARDIS in time. Eldane returns the warriors to hibernation by initiating a toxic fumigation; the humans escape, and Eldane hopes that in a thousand years, peace between humans and Silurians can occur. Tony, still affected by Silurian venom, opts to stay behind to be cured, and Nasreen also remains behind to study the earth from below and help improve human-Silurian relations.

Ambrose's family takes refuge in the TARDIS, but the Doctor, Amy, Lilith, Rose, and Rory find a crack in the cavern wall similar to those they have seen before. The Doctor surmises that the crack was caused by an explosion in time, which might have left shrapnel behind. He reaches in and pulls out an object which he wraps in a handkerchief. Before he can explain, Restac, dying from the toxic exposure, crawls around the corner and fires twice at the Doctor, but Rory gets in the way and Lilith tries to save him. Both take the shots; Rory dying in Amy's arms and Lilith beginning to regenerate. As the crack begins to absorb Rory's body, the Doctor and Rose realize that Rory will be written out of history and they forc Amy to board the TARDIS before the drill explodes. The Doctor tries to help Amy concentrate on remembering Rory, but Lilith's regeneration into her second body causes her to lose concentration and her memories of Rory are lost. The Doctor finds Amy's engagement ring, which Rory had stowed before the events, on the floor of the TARDIS. On the surface, Ambrose thanks the Doctor and Rose for not letting the Silurians execute her for killing Alaya, and the Doctor asks her to help prepare humanity for their next encounter with the Silurians. The Doctor, Rose, Lilith, and Amy return to the TARDIS, where Amy spies her future self on the hillside without Rory. The Doctor takes out the object he pulled from the crack: a burnt piece of the TARDIS's sign. He worriedly compares it to the real thing. Aside from the damage, they appear identical. The three Tyler-Lungbarrows share worried looks, and follow their companion inside.

The Doctor, Lilith, and Rose have taken Amy to the Musée d'Orsay in Paris, where they admire the work of the post-impressionist painter Vincent van Gogh. The Doctor discovers a seemingly alien figure in a window of the painting The Church at Auvers, and decides they must travel back in time to speak to Vincent around when he painted the painting. In 1890, they find Vincent at a cafe in Arles, a lonely man with a bad reputation. Vincent opens up when he notices Amy, sensing a loss she herself is not aware of. Outside the cafe a young girl is murdered, when the trio go out to see what happened they are stoned by locals who blame Vincent's insanity for the killing. Lilith and Amy talk Vincent into letting them stay the night and they return to his home. That evening, Vincent confesses that his works have little value to anyone else. He believes the universe is filled with wonders that he must paint, and that he can 'hear the colors'. Amy and Lilith go outside and are attacked by a beast that only Vincent is able to see. He sketches it for the Doctor, who identifies it as a Krafayis. Knowing the beast will appear when Vincent paints the nearby church the next evening, the Doctor, Rose, Amy, and Lilith plan to join him. The next morning, Vincent becomes distraught after being told that the Doctor and the girls won't be staying long. Vincent shuts himself in his bedroom, saying that everyone leaves him in the end. They set out to capture the beast alone, but Vincent soon joins them eager to help. He confides to Amy that if she can 'soldier on, then so can Vincent van Gogh'.

Vincent begins creating the painting of the church and soon spots the beast inside. The Doctor demands that Amy and Lilith stay back as he and Rose enter the church alone, but the girls and Vincent both agree they should help the Doctor. Vincent is able to save the Doctor, Lilith, Rose, and Amy by describing the beast's actions as they hide in the confessionals. The Doctor soon realises from Vincent's description that the beast is blind, the likely reason it was abandoned on Earth. The beast is impaled on Vincent's easel when it tries to lunge at the artist. The Doctor and Rose attempts to soothe the dying creature while Vincent empathises with its pain. After the creature dies, the three return outside the church and Vincent describes the night sky as he envisions it. The next day, Lilith, the Doctor, Rose, and Amy prepare to leave. Vincent asks Amy to return and marry him should she leave the other three. The Doctor offers to show him something. They take Vincent in the TARDIS to the present and the Van Gogh exhibit at the Musée d'Orsay. Vincent is stunned at the display and becomes emotionally overwhelmed when he overhears art curator Dr. Black say that Van Gogh was 'the greatest painter of them all' and 'one of the greatest men who ever lived'. They return an emotionally changed Vincent to the past and say their final goodbyes. As the Doctor, Rose, Amy, and Lilith return to the present, Amy is confident that there will be hundreds of new paintings by Vincent waiting for them. She is crushed to learn that Vincent committed suicide weeks after their adventure, at the age of 37. The Doctor explains that life is a mixture of bad and good, and while their brief encounter with Vincent couldn't undo all of the bad, they added some good to his life. The evidence is in Vincent's displayed works: the face no longer appears in The Church, and now Vase with 12 Sunflowers bears the inscription, 'For Amy'.

After stepping out of the TARDIS in modern-day Colchester, the Doctor and Rose are blown off their feet by a blast of air, and the TARDIS, Amy and Lilith still inside, dematerializes into the time vortex and refuses to rematerialize. With Amy and Lilith's help, Rose and the Doctor track the disturbance to the second floor of a house. The Doctor and Rose opt to take a room for rent offered by the downstairs tenant, Craig Owens, in order to determine what is present on the second floor without alerting whatever it is to his Time Lord nature. Neither Craig nor the Doctor and Rose are aware that people are being lured off the street to the second floor flat and never leaving again, but the Doctor is conscious of localized time loops and disturbances aboard the TARDIS that coincide with noises from the second floor. Over two days, the Doctor attempts to adapt to human life. He and Rose learn about Craig, an office worker with little aspiration to move onward. Craig is stuck in a platonic relationship with his co-worker, Sophie. The Doctor becomes overly involved in Craig's life, becoming the star player in Craig's local football club, filling in for him at the call centre when Craig falls ill, and encouraging Sophie to follow her dream of traveling overseas to help animals. Craig, who has not yet professed his love for Sophie, becomes upset; he accosts the Doctor and demands that he leave, which forces the Doctor to reveal his history and his reason for being in the flat, much to Rose's amusement.

Sophie arrives while they argue and is lured upstairs; the Doctor, Rose, and Craig follow, learning from Amy and Lilith that Craig's building has never had a second floor. Inside, they find an alien ship housing a primitive time engine. The ship crashed some time ago and has used a perception filter to disguise itself as part of Craig's house. The ship's emergency holographic program has been drawing in passersby, all who have a desire to escape, to find a replacement pilot for itself, but they were killed in the attempt. The machine identifies the Doctor as a possible pilot and tries to draw him to the controls, but the Doctor warns that if he should touch the controls, the ship could explode and take the solar system with it. The Doctor convinces Craig to touch the controls since he does not want to leave due to his love for Sophie, which will counteract the ship's protocols. Craig does so, and he and Sophie admit their love and share a kiss that breaks the ship's hold on the Doctor and themselves. The four escape in time to see the perception filter turn off and the ship implode, leaving Craig's undamaged one-story flat below. Craig and Sophie thank the Doctor and Rose, Craig giving him a spare set of keys in case they ever need it. Aboard the TARDIS, the Doctor directs Amy to write the note that led him to Craig's house, using a red pen in his jacket, unaware that she would find her engagement ring instead.

The Doctor, Rose, Lilith, and Amy, following a message from River Song, arrive in Roman Britain on Earth in 102 AD, where they find River posing as Cleopatra. She shows the Doctor a Vincent van Gogh painting titled The Pandorica Opens, which depicts the TARDIS exploding. River had recovered the painting in the 52nd century and travelled to the time-space coordinates on the painting using a time agent's vortex manipulator. The Doctor realises the Pandorica, a fabled prison for the universe's deadliest being, must be stored in a memorable location near the coordinates: Stonehenge. At Stonehenge, Lilith, the Doctor, Amy, Rose, and River find a passage to an underground area. Inside, they find the Pandorica, a giant metal box outfitted with every type of lock imaginable. While examining the Pandorica, Amy confronts the Doctor about an engagement ring she had previously found in the pocket of his jacket and feels a strong emotional attachment to; he says that it belonged to a friend, and that nothing is ever truly forgotten. The Pandorica is transmitting a signal amplified by Stonehenge's rocks across the universe, and River warns the Doctor and Rose that the signal is drawing everything that ever hated them to Earth that night. They are aided by a volunteer group of Roman legionaries; the centurion in charge of them is revealed to be Rory. Neither Rory nor the Doctor or Rose can explain Rory's presence, as he was consumed by a crack in the universe and erased from existence. When Amy comes around after being knocked out by a damaged Cyberman, she does not remember Rory, which upsets him greatly. The Doctor assures him that Amy will remember in time, and hands him the engagement ring.

The Doctor's enemies begin to orbit overhead, and the Doctor buys himself additional time with a threatening speech. He urges River and Rose to bring the TARDIS to Stonehenge while he, Lilith, Amy, Rory, and the legionaries prepare. When they try to use the TARDIS, an outside force takes control of it and pilots it to Amy's house in the present day. They discover landing patterns in Amy's garden and sees that someone has broken into the house. They finds in Amy's room a story book about Pandora's box and a children's book about Roman Britain. River communicates this to the Doctor, warning him that the Pandorica must be a trap, created out of Amy's memories. She identifies their current space-time coordinates as 26 June 2010, the date the Doctor identified as the onset of the time energy explosion that caused the cracks in the universe. The Doctor warns them to leave immediately. Back at Stonehenge, the Doctor discovers that the volunteer legionaries, including Rory, are Autons, and Lilith races to the surface to find Amy and Rory. The Doctor is quickly captured as his other orbiting foes materialise around him. He struggles against his captors, who reveal that they have formed an alliance to imprison him in the Pandorica. Knowing the TARDIS exploding would cause the cracks destroying reality, they believe only the Doctor can operate the TARDIS, and thus removing him will prevent the explosion and save the universe. As the Pandorica seals, all of the stars go super nova and everything stops.

The TARDIS's explosion has caused the whole universe to have never existed, except for the Earth, its moon, and a sun-like object, otherwise leaving a dark infinite void. Only stone versions of the Doctor's foes surround the Pandorica. As Rory and Lilith are mourning Amy, the Doctor appears using River's vortex manipulator. He hands Rory his sonic screwdriver and explains how to use it to open the Pandorica and free his younger self. Following these instructions, Rory and Lilith free the Doctor, who then places Amy's body inside the Pandorica. He explains that the Pandorica, being the 'perfect prison', will not allow its occupant to escape, not even by dying, and will restore her once given an imprint of her DNA. The Doctor then retrieves River's manipulator and uses it to jump ahead nearly two millennia with Lilith. Rory, in his ageless Auton body, decides to stay with the Pandorica and guard it. In 1996, seven-year-old Amelia Pond finds instructions from the Doctor leading her to the National Museum, where the Pandorica is on display. She touches the box, allowing it to revitalise Amy and release her. They are soon joined by the Doctor, Lilith, and Rory, now a museum guard who secretly survived the Blitz. After a tearful reunion, they are chased by a Dalek restored by the light of the Pandorica. The Doctor uses the vortex manipulator to go back and give Rory his screwdriver, as well as leave Amelia the clues to the museum. Amelia soon disappears: a sign, according to the Doctor, that the universe is collapsing rapidly. The injured body of a future version of the Doctor appears and whispers something to his earlier self. The Doctor takes off with Lilith, Amy, and Rory to the roof of the museum, where he discovers that the 'sun' is the still-exploding TARDIS. Rory hears voices coming from the exploding TARDIS and the Doctor amplifies the voice and discovers it is Rose and River in a time-loop, implemented by the TARDIS to keep them alive. The Doctor saves them, and as the group reunites, the Doctor is shot by the Dalek and sends himself backwards in time. Lilith, Amy, and Rory depart while River and Rose threaten the Dalek before the former shoots and destroys it.

Amy, Lilith, and Rory discover that the wounded Doctor had told his earlier self to create a diversion, allowing him to rig the Pandorica to fly into the TARDIS explosion. The Doctor postulates that enough of the original universe still exists in the Pandorica to completely restore it via the exploding TARDIS. After a tearful farewell to Lilith, Amy, Rory, and River where he instructs Amy to focus on her family, Rory, Lilith, and Rose to restore them in the new universe, the Doctor engages the Pandorica and flies it into the exploding TARDIS. A second Big Bang occurs. The Doctor comes to consciousness and begins witnessing events in his life in reverse as the cracks in the universe close. The Doctor has to stay outside this new universe in order for that to happen. After a final goodbye to Amelia on the night they met, he enters the cracks and disappears. As Amy recites the old proverb at her wedding, where Lilith is the maid of honor, the TARDIS and the Doctor appear. The Doctor comes out of the TARDIS and after a brief conversation with Amy, introduces himself by saying "Hello everyone! I'm Amy's imaginary friend, but I came anyway!" and joins the wedding festivities. He is shocked to find Lilith alive and back in her first body. She tells him that Rose and Darkel are waiting for them in London. Afterwards, the Doctor returns River's diary and the vortex manipulator to her so she can return to her own time. She sadly tells him he will soon learn who she truly is and that it will change everything. Aboard the TARDIS, the Doctor explains to Amy, Rory, and Lilith that unanswered questions remain about the destruction of the TARDIS and the nature of 'the silence' that will fall. The Doctor receives a telephone call alerting him to the presence of "an escaped Egyptian goddess on the Orient Express, in space". He tells the two humans that this will have to be goodbye. They agree that it is goodbye and Amy leans out of the TARDIS and yells "Goodbye!". The four then leave to pick up the rest of the Tyler-Lungbarrows and head on their next adventure.

A space liner carrying 4003 passengers, including Amy and Rory on their honeymoon, loses control when passing through strange electrified clouds over a human-inhabited planet. The Doctor and Rose, summoned by Amy, are unable to use the TARDIS to save the ship, and instead land on the planet and discovers that a spire in the centre of a large city is influencing the atmosphere. Its owner, the bitter and peevish old Kazran Sardick, refuses to operate the isomorphic controls to deactivate the spire and allow the ship to land safely. The Doctor observes Kazran's fear of his father who had built the spire, and creates a scheme inspired by Charles Dickens' A Christmas Carol to make Kazran kinder. He and Rose venture to Kazran's past and meets him as a kind-hearted young boy, interested in the unique properties of the planet's atmosphere that allow fish to swim in it. They experiment with Kazran, leading to a shark entering the room and swallowing the Doctor's sonic screwdriver. Though the Doctor is able to recover part of the screwdriver, the shark is wounded in the effort, unable to swim back into the atmosphere. Kazran offers a solution by taking him to a cryogenic storeroom where his father has kept people in storage as security for loans, including Abigail, a young woman with whom Kazran has been enamored. Abigail, once released, sings to soothe the shark while the Doctor uses Abigail's cryo-unit to transport the shark back to the atmosphere. As the Doctor and Kazran return Abigail to storage, Kazran promises her they will see her every Christmas Eve. The Doctor makes sure he keeps this promise, using the TARDIS to jump forward each year, helping to reunite Kazran and Abigail and watching their relationship blossom with the two falling in love and eventually kissing. However, after one such visit, Abigail tells the now young adult Kazran a secret, and Kazran requests the Doctor end the practice, keeping Abigail in storage indefinitely. Though old Kazran in the present becomes pleased with his new memories, he remains bitter at Abigail's fate and refuses to help save the ship. As a result of the Doctor's actions, instead of being cruel and heartless, Kazran is bitter and heartbroken.

Old Kazran is soon visited by holographic images of the ship's crew in the present. After observing the effects of Abigail's singing, the crew is singing Christmas carols, the sound frequencies of which are helping to stabilise the ship but cannot prevent it from crashing. Amy appears to Kazran and implores his help, but he waves away the holograms. The Doctor and Rose appear, and Kazran surmises that they are there to show Kazran his future, but he could not care less if he dies old and alone; he reveals that Abigail had an incurable disease on entering cryostorage and will only have one more day to live. As he cannot decide which day that should be, Kazran chastises the Doctor for believing he could change his mind. Unbeknownst to Kazran, the Doctor has brought young Kazran with him; the realization of how much his bitter future self now resembles his feared father causes a change of heart in Kazran and he quickly agrees to release the controls to save the ship. The Doctor finds their changes to Kazran's past have locked him out from the spire's controls, but Rose devises a solution: by having Abigail sing through one half of the broken sonic screwdriver, the other half, still in the shark, will resonate in the atmosphere and disrupt the storm to allow the ship to land safely. Kazran releases Abigail knowing this will be the last time, but Abigail understands and believes it is time for them to share a Christmas Day. The plan works successfully, and the resulting cloud break-out creates snowfall that falls around the city. As the Doctor and Rose rejoin Amy and Rory and prepare to take young Kazran back to the past, old Kazran and Abigail enjoy one last shark-led carriage-ride together.

Amy is trying to get the Doctor's attention while he fixes the TARDIS. She discovers that Rory is helping the Doctor by installing thermal couplings underneath the glass floor of the TARDIS. Rory, Lilith, and Amy then start a small argument about Amy cheating when she took her driving test, when the TARDIS suddenly shakes and the lights go out. Lilith accuses Rory of he dropping a thermal coupling, which he admits to and apologizes for doing. Amy then apologizes as well and, at the Doctor's confusion, Rose explains that Rory was looking Amy's skirt through the glass floor when he dropped the thermal coupling. The Doctor then notes that they have landed through emergency materialization which should have landed the TARDIS in the safest space available. The lights come on, revealing another TARDIS inside the control room-- the TARDIS has materialised inside herself. The Doctor experimentally walks through the door of the TARDIS inside the control room and instantly walks back into the control room through the door of the outer TARDIS. The Doctor tells the Tyler-Lungbarrow girls, Rory, and Amy that they are trapped in a "space loop" and that nothing can enter or exit the TARDIS ever again. Despite the Doctor's words, another Amy and Darkel enter through the TARDIS door and other-Amy says, "Okay, kids, this is where it gets complicated."

The other Darkel reveals that they are from a few moments in the future, and are able to come into the current outer TARDIS because the exterior shell of the TARDIS has drifted forwards in time. They know what to say and do because, from their perspectives, they are repeating what they heard themselves say earlier on. The Doctor sends the current Amy and Darkel into the TARDIS within the current TARDIS, in order to maintain the timeline. The two Amys take a moment to flirt with each other before the current one departs, much to the Doctor's exasperation and Rose and Lilith's amusement. However, not long after the current Amy and Darkel had left, Rory and Rose enter through the door of outer TARDIS explaining that the Doctor, from their perspective, has just sent them into the inner TARDIS. The current Doctor promptly sends the current Rory and Rose through the inner TARDIS. The Doctor then explains that he will set up a controlled temporal implosion in order to reset the TARDIS, but in order to do so he must know which lever to use on the control panel. Moments after he speaks, another Doctor enters though the outer TARDIS door and tells him to use the wibbly lever, which he quickly operates, then steps into the inner TARDIS to tell his past self which lever to use. The inner TARDIS dematerializes while the outer TARDIS (being the same TARDIS) does the same, and the Doctor assures everyone that they are now back in normal flight, and then advises Amy, "Pond, put some trousers on".

Regrouping at a diner, Amy, Rory, and River are shocked to find Rose, Lilith, and Darkel waiting there, saying that the Doctor would be back any moment. The Doctor walks in and reveals that he and his family were given an envelope, but don't know who sent it to them. The seven do a search on Canton Everett Delaware III and 'Space, 1969'. The TARDIS travels back to 8 April 1969, and ends up cloaked in the Oval Office. President Richard Nixon converses with Delaware about a series of phone calls he received from a young girl asking for help. The Doctor quickly gains Delaware's trust, convincing Nixon to give him a few minutes to locate the girl. The Doctor found the girl's location, a building near Cape Canaveral, Florida, at the intersection to streets named Jefferson, Adams, and Hamilton. The Doctor, the girls, and their companions leave in the TARDIS, followed closely by a curious Delaware. Upon arrival, they find pieces of a space suit and alien technology. River, Rose, and Darkel explore a vast network of tunnels that have apparently spread across the planet for centuries, Rose eventually sending River and Darkel back. Meanwhile, Delaware hears the little girl screaming and gives chase. As Amy, Lilith, and the Doctor follow, Amy tells them she is pregnant. When they find Delaware unconscious, a figure in an astronaut suit appears. Quickly, Amy picks up Delaware's gun and shoots at the suit. However, she realises too late that the helmet's visor has opened to reveal the little girl.

In the three months after, Lilith and Darkel, Amy and Rory, and River and Rose have been attempting to track the Silence, an alien race who cannot be remembered after they are encountered while the Doctor was being held captive. Ex-FBI agent Canton Delaware, under the ruse of capturing them as criminals, helps to reunite the group inside a special prison at Area 51 containing the TARDIS. Though they do not yet know the name or motive for the aliens, the Doctor's allies have discovered they exist across the entire planet, and have the ability to place post-hypnotic suggestions in humans they encounter. The Doctor plants a communication device called a nanorecorder in each of the group's hands to record audio of meetings with the Silence. As they travel to Kennedy Space Center shortly before the launch of Apollo 11, Amy tells the Doctor and Lilith she was mistaken and is not pregnant as she previously had claimed. While the Doctor alters part of the command module of Apollo 11, Canton, Lilith, and Amy visit a nearby orphanage, hoping to find where the girl in the spacesuit was taken from. Arriving too late, the Doctor and his allies find Amy's recording device. Canton is able to shoot and wound one of the creatures, and from it the Doctor discovers the creatures are the Silence, a group he was warned about by several of his foes in his recent adventures.

Analyzing the now-empty space suit, River realizes that the girl possesses incredible strength to have forced her way out of it, and that the suit's advanced life-support technology would have called the President as the highest authority figure on Earth when the girl got scared. The Doctor realizes why the Silence have been controlling humanity-- by guiding their technological advances, they have influenced humanity into the Space Race for purposes of building a spacesuit, which must somehow be crucial to their intentions. The Doctor uses Amy's communication chip to track her location, and lands the TARDIS in the Silence's control room five days later. As River, Lilith, Rose, and Rory hold the Silence at bay, the Doctor shows them the live broadcast of the moon landing. As they watch, the Doctor uses his modification of the Apollo command module to insert Canton's recording of the wounded Silent into the footage of the landing. Because of this message, humans will now turn upon the Silence whenever they see them. The group frees Amy and departs in the TARDIS, while River kills all the Silence in the control room. Amy says that she told Lilith, rather than Rory, when she believed she was pregnant through fears that travelling in the TARDIS might have affected her child's development. As the quartet sets off, the Doctor discreetly uses the TARDIS scanner to attempt to determine if Amy is pregnant.

Following a distress signal, the TARDIS lands aboard a 17th-century pirate ship stranded in the middle of an ocean. The ship's crew have been terrorised by a Siren-like creature who marks people with black spots on their palms after they are injured. Her song then lulls victims into a trance, making them want to go to her, which apparently disintegrates them. Rory receives a cut during a tussle with the pirates, and finds a black spot on his hand, but is prevented from succumbing to the song of the Siren by Amy, Rose, Darkel, Lilith, and the Doctor. Surmising the Siren is using water as a portal, the Doctor instructs everyone to seek refuge in the ship's dry magazine. There, they find Toby Avery, the son of the ship's captain Henry Avery, who stowed away on the ship in order to join the crew after his mother died, unaware of his father's illicit deeds. He too has a black spot on his palm due to a fever. In an attempt to escape, the Doctor, Rose, and Avery board the TARDIS, but find it is acting haphazardly, and are forced to evacuate, and they watch as it dematerializes by itself. After another shipmate is taken by the Siren in a dry room, the Doctor realises the Siren is using reflection to appear. In response they rid the ship of reflective surfaces, including the ship's stolen treasure.

When a storm begins, the crew start to set sail. Toby drops a polished crown while bringing his father a coat. The Siren is summoned and takes Toby. Soon, Rory and Darkel fall into the ocean, and the Doctor rationalizes that the Siren has shown intelligence and will likely get to them before they drown. Believing the victims are not dead, the Doctor convinces Avery, Amy, Rose, and Lilith to prick themselves. The Doctor's suspicions are confirmed when the Siren's touch actually teleports them to an alien spaceship, invisible in the same spot the pirate ship is located. The Doctor finds the spaceship's crew long dead from exposure to a human virus. The four then discover a sickbay where Avery's entire crew, Toby, Darkel, and Rory are in medical care. The Siren turns out to be the ship's virtual doctor, caring for the injured humans; the black spots are tissue samples used as references. Amy and Rose convinces the Siren to release Rory and Darkel into their care. Using Rory's nursing knowledge, Lilith, Amy, Rose, and the Doctor remove them from life support and are able to resuscitate them. Avery decides to stay with his son and his crew, unable to go back to England himself while the ship will care for his crew. Avery takes the helm of the spaceship and, along with Toby and his crew, sets off to explore the stars.

While in deep space, the Tyler-Lungbarrows, Amy, and Rory receive a communication cube containing a distress call from a Time Lord. Tracing the source of the call to a rift leading outside the universe, the Doctor deletes parts of the TARDIS to generate enough energy to traverse the rift. After landing in a junkyard on a solitary asteroid, the TARDIS shuts down and its matrix disappears. The four travelers explore the asteroid and meet its strange inhabitants: Uncle, Auntie, a green-eyed Ood called Nephew, and an excited young woman named Idris. Idris calls Rose 'my Wolf' and the Doctor 'my Thief', then bites him. While Nephew locks up Idris, Amy, Rory, and Darkel return to the TARDIS. The Doctor, Rose, and Lilith follow the distress signal and find a cabinet containing a large number of message cubes. Upon further investigation of Uncle and Auntie, the Doctor finds they are constructed of body parts from other beings, including Time Lords. They are controlled by the asteroid, called House, which is sentient and able to possess other technology around it. House led the Doctor there and removed the TARDIS's matrix, initially intending to consume its Artron energy. Upon learning that the Doctor is the last Time Lord and that no more will ever arrive, House transfers itself into the TARDIS to escape from the rift. Amy, Darkel, and Rory are trapped inside as the House-controlled TARDIS dematerializes.

The Doctor and Rose learn that Idris contains the personality of the TARDIS' matrix and that they can talk to each other for the first time. Without House's support meanwhile, Uncle and Auntie die, and Idris's body only has a short time before it too will fail. Idris reveals that House had stranded many TARDISes before, and that its universe is hours away from collapsing. The Doctor, Lilith, Rose, and Idris work together to construct a makeshift TARDIS from scraps, and then pursue House. Idris makes a psychic connection with Rory to give him directions to a secondary control room, where Darkel is able to lower the TARDIS' shields without House's interference. This allows the Doctor, Rose, and Lilith to land the makeshift console in the secondary control room, which atomizes Nephew. House deletes the secondary control room as he prepares to break through the rift, which the Doctor anticipates. The TARDIS's safety protocols transfer them to the main control room, where the dying Idris releases the TARDIS's matrix back to the TARDIS, destroying House. A remnant of the TARDIS's matrix, in Idris' body, sadly states that she will not be able to speak to the Doctor or Rose again but will be there for them. Idris's body then disappears as the TARDIS matrix is fully restored. The Doctor installs a security field around the matrix to prevent it from being compromised again. Rory tells the Doctor that some of Idris's final words were 'the only water in the forest is the river', which neither the Doctor nor Rose understand. After Amy and Rory leave to find a new bedroom, and Lilith leaves to find hers, the Doctor talks to the TARDIS, and in response a nearby lever moves on its own, sending the TARDIS to its next destination.

The TARDIS is caught in the first waves of a solar tsunami and materializes on Earth in the 22nd century. The Doctor, Rose, Amy, and Rory find themselves on a remote island, where a factory housed in a former castle monastery pumps a valuable, highly corrosive acid to the mainland, Lilith and Darkel having requested to stay in the TARDIS. The skeleton crew of the factory uses a self-replicating fluid called the Flesh from which they create doppelgängers of themselves, colloquially called 'Gangers'. The crew control the Gangers from special harnesses, operating in the hazardous environment of the factory via the disposable bodies. The Doctor, initially posing as a weatherman, fears the worst part of the solar tsunami will strike the solar-powered factory soon, threatening those still remaining, and offers to take the crew in his TARDIS. The foreman, Miranda Cleaves, refuses to shut down the factory until she receives orders from the mainland. As the solar storm begins, the Doctor and Rose race to disconnect the solar collector, but an electrical strike hits the castle, throwing the Doctor off the tower and knocking everyone inside unconscious.

When the crew awaken, they find themselves out of the control beds with no sign of the Gangers. However, their own personal belongings have been gone through and the TARDIS has sunk into acid-corroded ground. The Doctor explains that they have likely been unconscious for more than an hour and the Gangers have gained sentience. They soon discover that two of the Gangers are amongst them, posing as Cleaves and Jennifer, when the two give themselves away by turning pale-white. Jennifer also exhibits the ability to contort and stretch her body well beyond human limits. The Jennifer Ganger struggles with her new identity and befriends Rory who has begun to demonstrate an emotional attachment to her. The Cleaves Ganger works in secret with the other Gangers to try to kill the real humans, as the human Cleaves plans to kill the Gangers. The Doctor and Rose attempt to reunite the two sides but fail when the human Cleaves kills one of the Gangers with a high-powered electrical charge. The Gangers plan an attack, and the Doctor accuses Cleaves of killing a living being which Cleaves refuses to acknowledge. The Doctor determines that in a monastery, the safest place to be is the chapel, and directs everyone there. The Gangers, in acid-protection suits, bear down on the chapel. Rory responds to the sound of Jennifer screaming by deliberately separating from the group, against Amy's wishes. In the chapel, Amy, Rose, and the Doctor discover a Ganger version of the Doctor.

The Ganger of the Doctor differs only from the real Doctor by his shoes. Though the Ganger Doctor appears ready to help the crew to contact the mainland to request rescue, Amy is distrustful of the being, particularly after it advances on her after she asks about the Doctor's death she witnessed. Eventually, Cleaves orders the two Doctors separated; the Ganger Doctor and another crewman go looking for Rory, who had gone off alone to find the emotionally distraught Jennifer. Jennifer had managed to convince Rory to lead the human group into the acid storage chamber and traps them inside; crewman Jimmy is killed trying to stall the acid release. The Ganger Doctor has met with the other Gangers, and discovers their unwillingness to proceed. He uses the opportune call of Jimmy's son on his birthday to convince the Ganger Jimmy and the other gangers they are just as real as their human counterparts. Ganger Jennifer becomes furious at this display and rages off; the other Gangers agree to work with the humans to escape the facility. They free the humans trapped in the acid storage room, and race off through the crypts below the monastery, chased by a savage Ganger Jennifer who has transformed herself into a monster. Both Ganger and human sacrifice themselves to stall the monster while letting the rest of the group escape.

They eventually come onto a room where the TARDIS, having been trapped in a pool of acid outside, has fallen into the crypt. Ganger Cleaves offers to hold the door to allow the rest to escape, and the Doctor soon joins her, stunning Amy. To her surprise, the Doctor reveals that he and his Ganger had switched shoes long ago. Amy apologizes to the Ganger Doctor, who accepts but warns her, "'push, Amy, but only when she tells you to". As the surviving humans and Gangers escape to the TARDIS, the Cleaves and Doctor Gangers together face the monster, triggering a sonic screwdriver at the right moment to cause them and the monster to dissolve back into liquid. Aboard the TARDIS, the Doctor indefinitely stabilizes the Gangers' forms, while providing Cleaves a cure to her terminal condition. He drops the factory crew at their headquarters where they plan to reveal the truth of the Flesh to humanity. As the TARDIS crew turns to leave, Amy starts feeling contractions. Back aboard the TARDIS, the Doctor admits his trip to the factory was planned: he wanted to investigate the Flesh in its raw form, as he, Rose, and Lilith had known for some time that Amy is a Ganger herself. Lilith holds Rory back as the Doctor promises Amy that he will find her and then disrupts her form, turning her back to raw Flesh.

The Tyler-Lungbarrows have come to learn the real Amy is being held on a secret asteroid base called Demon's Run, and collect several old debtors from across time and space to lay assault on the base, including Captain Jack Harkness, Sontaran Commander Strax, Silurian Madam Vastra and her human companion Jenny Flint, and the black market trader Dorium Maldovar. Assisted by additional Silurian and Judoon forces, the Doctor and his allies launch a surprise attack and secure the base. The Doctor, Rose, Lilith, and Rory free Amy and retake Melody before Madame Kovarian can escape with her. As the Doctor celebrates, considering this his greatest achievement, Vastra and Dorium discover Kovarian has been scanning Melody and has found the child has both human and Time Lord DNA. The Doctor surmises Melody was likely conceived on Amy and Rory's wedding night aboard the TARDIS, the baby's DNA influenced by the time vortex. The rest of the Doctor's allies regroup, and Amy and Rory tend to their daughter using an ancient wooden cot the Doctor claims was his own. Lorna Bucket arrives and warns the group of Kovarian's trap, but they are too late, as the TARDIS is blocked by a forcefield. They are attacked by the Headless Monks, and several Silurians are killed immediately. Dorium and Jack are beheaded, while Strax and Bucket are fatally wounded in the battle.

Meanwhile, Kovarian, well away from the base, contacts the Doctor and Rose, explaining they will be using Melody as a weapon in the war against them. She takes delight in telling the Doctor he has fallen into another trap, and fooling twice in the same way is a privilege. The Doctor and Rose race to the hangar to warn their friends, unaware they are too late. They arrive too late to help their wounded allies, and so Lilith, Rose, and Rory console Amy. Lorna Bucket dies, remembering her childhood adventure with the Doctor and Rose. River appears, and the Doctor berates her for not helping. She tries to explain she could not have interfered in these events, and tells the Doctor what transpired was partially his fault, having been brought about by those who feared his reputation. The Doctor becomes angry and demands to know who she is. River shows the Doctor the cot, and he recognizes her identity. Elated, he drags Rose and Lilith into the TARDIS to rescue Melody, asking River to return everyone to their proper time period. While Rose and the Doctor start planning their search for Melody, Rose notices that Lilith is acting strange. The Doctor asks Lilith is she knows anything about where Melody is and Lilith says that she swore she’d never tell and that she’s not allowed to give them any spoilers.

In modern-day Leadworth, Amy and Rory create a crop circle to gain Tyler Lungbarrows' attention via its newspaper coverage. They arrive with the TARDIS, but they are soon joined by Mels-- Lilith, Amy, and Rory's childhood friend who knows of Amy's 'raggedy Doctor' and was, along with Lilith, responsible for Amy and Rory's relationship; Amy had subsequently named her daughter Melody Lilith after the two. On the run from the police after stealing a car, Mels brandishes a gun and coerces them to escape in the TARDIS and kill Hitler. Inside, she fires the gun, hitting the time rotor which fills the time machine with a poisonous gas and sends it out of control. The TARDIS crashes into Hitler's office. Hitler, already panicked, fires on the Teselecta, but his aim is poor and strikes Mels. As Rory punches Hitler and locks him in a cupboard, the TARDIS crew finds Mels regenerating, becoming River Song. Having been trained by her captors to kill the Doctor, Melody makes several attempts but the Doctor has taken precautions to nullify these. Instead, she kisses him and, before disappearing into the streets of Berlin, reveals that her lipstick is poison from the Judas Tree, which will kill the Doctor within the hour and prevent his regeneration. The Doctor orders Amy and Rory to follow Melody, passing Amy his sonic screwdriver, while Lilith, Darkel, and Rose help him return to the TARDIS to try to discover a cure.

The Tesalecta takes on Amy's appearance, allowing the robot to get close to Melody to attack her. Before they can complete the attack, the TARDIS materializes. The Doctor, spurred on by the TARDIS' voice interface hologram of Amy's younger self, has found time to dress for the period and stops the attack, now aware of the Teselecta's nature. The captain speaks to the Doctor, informing him that Melody has been trained to kill him by the Silence, a religious order that believes that when the oldest question in the universe is asked, silence will fall across the universe. When the crew refuse to back down from attacking Melody, Amy uses the sonic screwdriver to turn the robot's 'antibodies' against the crew. The crew abandon the robot by being teleported away by their mothership, leaving Amy and Rory to face the antibodies. The Doctor finds himself too weak from the poison's effects to pilot the TARDIS to rescue his companions and his family doesn't want to leave him. Melody is inspired by the Doctor's sympathy, and finds herself guided by the TARDIS itself to pilot the ship, and rescues Amy and Rory in time. On returning to the café, the trio finds Lilith and Darkel crying, Rose at the Doctor's side, and the Doctor near death. He asks Melody to find 'River Song' and give her a message, then whispers something in her ear before he passes away. Melody, who at this point still only knows herself as Melody Pond, asks Amy who River Song is. Amy uses the Teselecta to show her form stored in the robot's database of who she is to become. With this, Melody sacrifices her remaining regenerations to bring the Doctor back to life, and passes out. The Doctor, Rose, Lilith, Darkel, Amy, and Rory take her to a hospital in the far future, leaving the TARDIS-shaped diary as a gift by her bedside, and depart. Aboard the TARDIS, the Doctor and Rose have discovered the date of the Doctor's death from the records aboard the Teselecta, but don't reveal this knowledge to Amy or Rory.

While Darkel and Lilith are visiting Lilith's godmother, Sarah Jane, the Doctor and Rose decide to make a 'house call' after the psychic paper receives a message from George, a frightened 8-year-old child, asking his help in getting rid of the monsters in his bedroom. On arrival at a council estate on present-day Earth, Rose, the Doctor, Amy, and Rory split up to try to locate the child. The Doctor and Rose, taking the guise of social services workers, find the right apartment, and meet George's father, Alex, while his mother Claire is working a night shift. Through Alex's photo album, the Doctor learns that George has been frightened all his life, fearing many of the sounds and people around the apartment and is helped to cope by utilizing various habits, including metaphorically placing his fears within his wardrobe.

The Doctor, suspecting that the wardrobe contains the evil George fears, opens it to find its contents are simply clothes and toys, including a doll house. He suddenly recalls from Alex's photo album that Claire did not appear pregnant in the weeks leading up to George's supposed birth, causing Alex to remember the fact that Claire was unable to have children. The Doctor asserts that George is a Tenza child, an empathic alien who took on the form of Alex and Claire's desired child through a perception filter, and has the ability to literally lock away his fears within the wardrobe. George begins to panic from this revelation and the Doctor, Rose, and Alex are pulled into the wardrobe, joining Rory in the dollhouse. As the dolls descend on the four, the Doctor calls out to George to face his fears; George is able to open the wardrobe and appears in the dollhouse, but the dolls turn to advance on him. The Doctor realizes that George is still frightened that Alex and Claire plan to send him away, having mistakenly interpreted a conversation they had earlier that night; Alex rushes through the dolls to embrace George as his son. They all soon find themselves back at the estate, restored to normal. Claire returns the next morning to find George no longer scared while Alex and Rose make him breakfast. After being thanked, the duo rejoins their companions to set off for their next adventure.

The TARDIS, while travelling to a new planet, arrives in what appears to be a 1980s Earth hotel, but the Doctor recognizes it as an alien structure specifically designed to take that appearance. They soon meet a group of three individuals-- humans Rita, Howie and the alien Gibbis-- each of whom had previously been taken from their routine lives to find themselves in the hotel. They are also introduced to Joe, a human who has already succumbed to a madness that infects everyone who sets foot in the hotel, and so has been tied up for his own protection. The four explain that there is a beast in the hotel that consumes everyone who has been trapped here. It does this by enticing them to enter one of the many rooms in the hotel which contains their greatest fears, upon which they become brainwashed to 'praise him' and allow themselves to be taken, their bodies left without any signs of life; many others have experienced this, and photos of them and their fears cover many of the hotel's walls. The hotel would seem inescapable, its doors and windows walled up, and its halls and rooms can change on a whim. The Doctor, Rose, Lilith, Amy, and Rory soon find the TARDIS has also disappeared, and the Doctor warns them from opening any door they are drawn to, for fear of being possessed. As the Doctor tries to ascertain the situation, the group is thrown into panic when they hear the beast coming for Joe, and hide in rooms where Rita and Gibbis face their fears. The Doctor spies the Minotaur-like beast through a keyhole, just before Joe escapes from confinement and is killed. Howie soon becomes possessed after entering a room against the Doctor's warnings. The remaining group set up a trap to lure the beast into the hotel's hairdressing salon using Howie's voice, upon which the Doctor questions the trapped creature and learns it is in agony wishing for its end.

The Doctor realises the hotel is really a prison for the creature, and the 'fears' in each room are harmless illusions. Howie also escapes from the group, allowing the beast to escape and chase him down, killing him before the Doctor can save him. While exploring more of the hotel, Lilith, Amy, and the Doctor are separately lured to look into three specific rooms, facing their own fears. Rita also begins to praise the monster, and after thanking the Doctor for trying to save her, follows the fate of Joe and Howie. The Doctor, Rose, Amy, Rory, Lilith, and Gibbis regroup, and the Doctor surmises that the other three believed in some form of faith. The hotel and its rooms were, by design, meant to challenge their faith by fear to allow the beast to possess them. The Doctor identifies that Gibbis has survived due to the extreme cowardice of his species, while Rory and Rose* lack any such faith to be broken. However, the Doctor realizes that it is Amy's trust in him that is being challenged; it is that faith that brought them to the hotel in the first place. Amy soon becomes possessed like the others. As the beast comes for her, the Doctor and the others grab her and take her to the room she opened previously. Inside, they find the illusion of young Amy still waiting for the return of her 'raggedy Doctor and his friend'. The Doctor asserts to Amy that he is not a hero, but just a mad man with a box to break her blind trust in him. Once this is done, the beast outside the door collapses on the floor. As they watch, the hotel is revealed to be part of a large simulation. The Doctor identifies themselves aboard an automated prison spaceship, and the beast as a relative of the Nimon, a creature that feeds off the faith of others. The ship's automated systems had provided it 'food' by bringing aboard creatures who had a strong faith. The beast mutters that death would be a gift for the Doctor before it passes away. The Doctor finds the TARDIS nearby, Gibbis asks for a lift home and the Doctor, Rose, and Lilith then take Amy and Rory to London, the Doctor believing it best for the two to stop traveling with them before they end up getting killed. Giving them a new house and car, the three others set off in the TARDIS to pick up Darkel from the Smiths'.

{*While Rose should've had faith in the Doctor like Amy, she had lost that faith in the Time Lord Doctor when he abandoned her on Bad Wolf Bay with the Metacrisis and it was Lilith who returned to Pete's World to retrieve her, not him.}

Nearly two hundred years have passed for the Doctor and Rose since they left Amy and Rory behind and they are on a farewell tour of his friends as he knows he has only one day to go before his death. They stop by Craig, who is living with his girlfriend Sophie in a new home and is raising their baby, Alfie. Craig, struggling to care for Alfie alone while Sophie is away for the weekend, suspects the Doctor and Rose are investigating something alien. The two prepare to leave, but notice a strange electrical disturbance in the area and decide to investigate. Craig, while at a new department store with Alfie, discovers the Doctor working in the toy area. The Doctor reveals that he and Rose have traced the electrical disturbances to the store and is using the job to allow him to investigate further, hearing rumours of the disappearance of several shop assistants and the sightings of a silver rat. The Doctor and Craig enter an elevator and find themselves teleported to a Cyberman spacecraft. A Cyberman emerges from the darkness and comes towards them but the Doctor manages to reverse the teleporter and disable it. As Craig returns home, the Doctor sees Amy and Rory shopping but stays out of their sight. With Craig's help, the Doctor and Rose enter the store after hours and catch a Cybermat, which has been siphoning small amounts of energy to the spacecraft. They also encounters a malfunctioning Cyberman in the building's basement, and are curious how it arrived in the store. At Craig's house, while the three are distracted, the cybermat reactivates, but they are able to stop it, and the Doctor reprograms the unit to track down the Cybermen signal.

The Doctor and Rose leave on their own to locate the Cybermen at the store but Craig shortly follows, bringing Alfie along. The two Gallifreyans finds the spaceship actually sits below the store, underground, accessed by a tunnel from a changing room. The ship has been slowly siphoning energy from the store's power lines, reactivating its crew. They are captured by the Cybermen, who tell them that their ship crashed long ago but, with this new energy, will soon have enough power to convert the human race. Craig, leaving Alfie with a store clerk, follows them into the tunnel, and is also captured and placed into a conversion machine. The Doctor reveals his own impending death and urges Craig to fight, but the conversion appears to be complete. Alfie's cries over the closed-circuit television echo in the ship. Craig, encouraged by the Doctor telling him that this is his chance to be a father, fights and reverses the conversion. The rest of the Cybermen painfully experience the emotions they have repressed from Craig's struggle, and their circuits start to overload. The Doctor, Rose, and Craig escape via the teleporter as the ship explodes, the blast contained by the cavern. Craig reunites with Alfie, while Rose and the Doctor slips away unseen. Craig returns home to find them already there, having used time travel to clean the house. The Doctor tells Craig that Alfie now has a much higher opinion of his dad. They leave just before Sophie returns. Nearby, the Doctor tells the TARDIS he knows this is their last trip in her and offers some parting words to a small group of children.

The Doctor, aware of his imminent death at the fixed point of time on 22 April 2011 at Lake Silencio in Utah, attempts to track down the Silence to learn why he must die. He encounters the Tesalecta shapeshifting robot and its miniaturised crew who are currently posing as one of the members of the Silence; they offer him any help within their power as he faces his death. Through them, the Doctor is led to the living head of Dorium Maldovar, one of the Doctor's allies taken by the Order of the Headless Monks. Dorium reveals that the Silence are dedicated to averting the Doctor's future, warning him "On the fields of Trenzalore, at the fall of the Eleventh, when no living creature can speak falsely or fail to answer a question will be asked—one that must never be answered. And Silence must fall when the question is asked.” The Doctor continues to refuse to go to Lake Silencio until he discovers his old friend the Brigadier has died, at which point he accepts his fate. To avoid crossing his own time stream, he gives the Teselecta crew four invitations to Lake Silencio for Amy and Rory, River, Canton Everett Delaware III, and a younger version of himself and his family. Leaving Rose and Darkel in the TARDIS, the Doctor joins his friends and Lilith at Lake Silencio and then approaches the astronaut, a younger version of River. She does not want to kill him but is unable to fight the suit's control, and the Doctor says he forgives her and reminds her that the event is inevitable. River, despite his warning against interfering with a fixed point, surprises the Doctor by draining the astronaut suit's weapons systems and averting his death. Time becomes ‘stuck’ as a result and begins to disintegrate; all of Earth's history begins to run simultaneously at a fixed moment of 5:02 p.m. on 22 April 2011. In London, Holy Roman Emperor Winston Churchill takes the Doctor, his ‘soothsayer’, out from his locked cell to ask him about the condition of time.

The Doctor explains the preceding events, as tally marks begin appearing on his arms, indicating the presence of the Silents. After noticing a Silents’ nest overhead, they are rescued by Lieutenant Amy Pond, Major Lilith Smith, and a squad of soldiers under their command. Due to the effects of the crack in her bedroom wall, Amy is cognizant of the altered timeline, though she is unaware that her trusted captain is her Rory. Amy and Lilith take the Doctor to Area 52, a hollowed-out Giza pyramid, where they have captured over a hundred Silents and Madame Kovarian. River is also there, aware of the consequences of her actions she refuses to allow the Doctor to touch her, an event that would ‘unfreeze’ time and allow it to resume. They all wear ‘eyedrives’, external memory eye patches, which enable them to avoid the Silents’ effect of erasing themselves from memory. They realize that this was a trap arranged by Kovarian, as the Silents begin to escape confinement and overload the eyedrives, killing their users. The Doctor and River escape to the top of the pyramid while Lilith, Amy, and Rory fight off a wave of Silents and Amy realizes who Rory is. Madame Kovarian dislodges her own eyedrive as it begins to overload, but Amy forces it back in place with the intention of killing her as revenge for Kovarian taking her child away. Amy, Rory, and Lilith regroup with River and the Doctor. River tries to convince the Doctor that this frozen timeline is acceptable and that he doesn’t have to die, but the Doctor explains that all of reality will soon break down. Lilith steps up and backs up the Doctor’s explanation. Lilith tells River to save the universe and “do it Melody Pond style.” River kisses the Doctor and reality returns to normal. Eventually, the Doctor takes Dorium's head back to where it was stored and explains that his perceived death will enable him to be forgotten as he had been getting "too big" and drawing too much attention. As the Doctor leaves, Dorium warns of the prophecies that still await him and the question which Dorium calls out after him: "Doctor who?"

In the ruins of Skaro, homeworld of the Daleks, the Doctor, Rose, Lilith, and Darkel are approached by Darla von Karlsen, who requests his help in freeing her daughter from a Dalek prison camp. The Doctor's suspicions are confirmed when Darla turns out to be a humanoid Dalek puppet and teleports them to the spaceship housing the Parliament of the Daleks. There they are reunited with a now divorced Amy and Rory, who have been similarly kidnapped from present-day Earth, just after Rory has delivered Amy their divorce papers. The Doctor and Rose are surprised when, rather than exterminate them as they expect, the Daleks ask them for help. The Dalek Prime Minister explains that they have a planet known as the Asylum, which the Parliament is currently orbiting, where they keep battle-scarred Daleks that have gone insane. They are unwilling to kill these Daleks, as destroying such pure hatred would contravene their sense of beauty-- something which sickens the Tyler-Lungbarrows. The Parliament has received a transmission of the Habanera Aria from the heart of the Asylum. The Doctor makes contact with the source of the transmission: a woman named Oswin Oswald, who states that she was Junior Entertainment Manager on the starliner Alaska, which crashed into the Asylum. Oswin claims to have been fending off Dalek attacks for a year, occupying herself by making soufflés, which intrigues the Doctor as he wonders where she got the milk and eggs. The crash had ruptured the planet's forcefield, thus risking escape of the planet's inmates. To prevent this, the Parliament wishes to destroy the planet remotely, but the forcefield is not ruptured sufficiently to allow that. The forcefield can only be deactivated from the planet itself, but afraid to face such a mission themselves, the Daleks task the Doctor, his family, Amy, and Rory with doing so. The six are given bracelets to protect them from the planet's nanogene cloud, which would convert them into Dalek puppets to serve the facility's security systems, before being dropped through the forcefield breach onto the surface of the planet via a gravity tunnel. The Doctor, Rose, Lilith, and Amy land close to each other, and are discovered by Harvey, another survivor from the Alaska. Harvey guides Lilith, the Doctor, Rose, and Amy to his Alaska escape pod, where he attacks them after being revealed as a Dalek puppet, converted by the nanogene cloud. A similar fate has befallen the corpses of other Alaska survivors, who re-animate and attack the three, stealing Amy's nano-field bracelet just before the pair are saved by Oswin, who also guides them to Rory and Darkel through a hatch in the bottom of the pod. Now unprotected against the nanogenes, Amy begins to be converted, experiencing memory loss and hallucinations.

The Doctor guesses that the Daleks will destroy the planet as soon as he deactivates the forcefield, but he realizes that Rory and Darkel's hideout is a telepad, via which they can teleport onto the Dalek Parliament ship. Oswin agrees to deactivate the forcefield in return for the Doctor, Rose, and Lilith coming to rescue her. They make their way to Oswin, venturing through the 'intensive care section', which holds Daleks who survived encounters with the Doctor. They begin to re-activate, but he is saved by Oswin, who deletes the Doctor and Bad Wolf from the Daleks' collective telepathically-shared knowledge, leaving them with no memory of Rose or the Doctor. The Doctor has never been able to hack into their hive intelligence, let alone remove anything from it, and is confused to how she has done so. They enter Oswin's chamber, only to discover that she is really a Dalek. It turns out that Oswin had been captured by Daleks after the Alaska crashed on the Asylum and, to preserve her genius-level intellect for Dalek use, was turned into a full Dalek rather than a standard puppet. Unable to cope with her conversion, her mind retreated into a fantasy of survival as a human. The Doctor had suspected that something was wrong from the beginning, however, as one of the things Oswin had kept herself busy with while in hiding had been making soufflés, which the Doctor noticed would be impossible to get the ingredients for. Oswin is nearly overcome by her Dalek personality at this revelation, but she still possesses human emotions and is unable to kill the trio. Lilith raises her voice and begs Oswin to remember who she is and not kill them. Oswin fulfills her promise of deactivating the forcefield, making her final request that they remember her as the human she once was. The Doctor, Rose, and Lilith return to Darkel, Amy, and Rory, and they teleport back to the TARDIS just as the planet is destroyed. The Daleks fail to recognize the Doctor or Rose due to their removal from their hive intelligence. They jubilantly leave the ship, and drop the reunited Amy and Rory back home. The family departs, the Doctor delighting in the Dalek Parliament's closing question to him: "Doctor who?"

While in 1334 BC Egypt with Queen Nefertiti, the Tyler-Lungbarrows receive a call from the Indian Space Agency in 2367 about a vast spaceship which will crash into Earth in six hours. The ISA plans to destroy it with missiles unless the Doctor stops it first. Taking Nefertiti with them, they pick up Edwardian explorer John Riddell from the African plains in 1902. The Doctor then materializes the TARDIS around their companions Amy and Rory ten months after he last saw them, inadvertently taking Brian, Rory's father, on the TARDIS as well. They materialize in the spaceship and find that it contains dinosaurs. When asking the ship's computer for the engines, the Doctor, Lilith, Rory, and Brian are transported to the engine room, a large beach on the ship which uses the waves as hydro-power. After escaping from a group of pterodactyls, Lilith, the Doctor, Rory, and Brian are escorted by two robots to the only human on board, a brutal man called Solomon who has been injured in a raptor attack and requires medical help.

Scanning the Doctor to see who he is, Solomon is surprised that the Doctor does not appear in his universal database. Solomon reveals himself to be a lawless exotic black market trader who has raided the spaceship in order to steal the dinosaurs. Having had the robots murder all of the Silurians, Solomon was unable to take control of the ship himself and the computer defaulted to its point of origin, causing it to return to Earth. Discovering Queen Nefertiti's identity and value, he decides to kidnap her and leave in his own ship. Though the Doctor refuses, Nefertiti agrees to go with him to save the others, despite the man's obvious sadistic intentions towards her. While Amy, Rose, and Riddell shoot hostile dinosaurs with a tranquilizer gun, the Doctor disables Solomon's robots and rescues Nefertiti, then tricks the ISA missiles into targeting Solomon's ship rather than the ark: it is destroyed, taking him with it. Rory and Brian pilot the ark away from the Earth, as the ship can only be piloted by two people of the same gene chain. The Doctor and his family then take Amy and Rory back to their home after letting Brian view the Earth from orbit.

The Doctor, Rose, Lilith, Darkel, Amy, and Rory, while en route to the Day of the Dead festival in Mexico via the TARDIS, instead arrive at the small American Frontier town of Mercy. The Doctor is curious as to a ring of stone and wood that surrounds the town's border and the availability of electricity to the town ten years too early. They learn from the town's marshal, Isaac, that they have been kept within town for the last three weeks by 'The Gunslinger', who uses alien weaponry to threaten to kill anyone trying to leave town and blocks the town from receiving any supplies. The Gunslinger has demanded the town turn over 'the doctor', which the Doctor deduces is not himself but a humanoid alien hiding in the marshal's jail. The alien introduces himself as Kahler-Jex, who had crashed on Earth about ten years earlier, and was rescued from his craft by the town; in return, Jex has helped the town as their physician, ending a cholera outbreak and providing the town with primitive electricity. However, the town's food supplies are nearly empty, and while the situation has become more dire, the marshal is reluctant to hand over Jex. The Doctor offers to get the TARDIS and evacuate the town, he and Rose riding off on horseback to collect it while Isaac, Rory, and the girls distract the Gunslinger. The Doctor and Rose come across Jex's craft and enter it, though in doing so they set off an alarm heard across the plains. The Doctor reviews Jex's records and discovers that Jex was part of a team of scientists from his war-torn homeworld that experimented on a number of volunteers to convert them into cyborgs, who either died or killed countless people in the battle. Aghast, the two leave the ship to find the Gunslinger waiting for them, and they realize that the Gunslinger is one of Jex's subjects. The Gunslinger affirms that he is seeking revenge on those that created him, with Jex being the last member alive; he further explains that his programming prevents him from harming innocents, creating the ring around Mercy to protect the townsfolk while Jex is in their care, but demands of the Doctor that the next person that crosses that line must be Jex.

The Doctor and Rose return to Mercy, and Rose angrily drags Jex to the edge of town, followed by their companions and the concerned townsfolk. As she forces Jex to cross the line, Amy notes that this is not normal behavior for Rose. The Gunslinger arrives and holds his weapon to Jex; Jex tries to offer that he has become better and rejects his past actions, but this does not sway the cyborg. As the Gunslinger is about to fire, Isaac pushes Jex out of the way, taking the lethal shot. Isaac's final action is to hand his marshal badge to the Doctor and ask him to protect the town. The Gunslinger leaves, warning that he will return at noon tomorrow to collect Jex, even if it puts the townspeople at risk. During the night, Jex explains his guilt to the Doctor, trying to repent for his past knowing what will await him in his afterlife: his culture believes that upon death, one must carry the souls of everyone they have ever wronged up a mountain, giving Jex an unbearable load. An angry mob of townsfolk arrive to demand Jex, but the Doctor warns by doing so they would have not honored Isaac's death. Further discussions with Jex provide the Doctor with an idea for a plan. The next day, when the Gunslinger arrives the Doctor distracts it by amplifying the electricity sent through town, while other townsfolk, wearing makeup applied in the same fashion as Jex's facial markings, dash between buildings to confuse the cyborg. Jex flees out of town to his ship as the Doctor planned, but instead of returning to space, Jex initiates the ship's self-destruct. Before he dies, Jex explains that no matter where he goes, the Gunslinger will follow and more innocents will be caught in the crossfire. Truly wishing to repent of his past actions, he declares that his last act will be to end the war for the Gunslinger and go to face the souls of those he wronged. The Gunslinger becomes desolate with his quest for revenge complete and the realization that Jex was no worse a person than he is. Recognizing that there is no need for a creature of war during a time of peace, the Gunslinger announces his intent to self-destruct far away from town, but the Doctor suggests that he could become the protector of peace as the new marshal. The Doctor and the girls take Amy and Rory home, while the Gunslinger stays on to watch over Mercy.

Amy and Rory have tried to adjust to normal life without traveling with the Tyler-Lungbarrows. One day billions of small black cubes appear around the globe, but they appear to be inert and invulnerable. The Doctor arrives to help, having been alerted by news stories. UNIT storms the Ponds' house soon after in response to the duo's arrival. The UNIT force is led by scientific adviser Kate Stewart, the daughter of the Doctor's friend and former UNIT commander, Brigadier Lethbridge-Stewart. Kate explains that they have no idea of the purpose of the cubes and hope the Doctor can help. After several days of watching the cubes without anything out of the ordinary occurring, the Doctor decides there is no problem and puts Rory's father Brian in charge of watching the cubes as he returns and departs in the TARDIS. Over the following year, Amy and Rory live out their lives, making commitments despite not knowing if they will always be around. The Tyler-Lungbarrows visit them at Amy and Rory's wedding anniversary party and take them on a trip for seven weeks, though returns them a few minutes after leaving. Brian notices their absence and, in private, asks the Doctor the fate of his previous companions. The Doctor admits that, aside from Rose, while most had left on their own or were left behind, some have died, but promises that will not happen to Amy or Rory. Humanity forgets about the cubes' arrival, and use them as paperweights and similar mundane functions. A year after their arrival, the cubes start to activate, scanning the world's information networks and acting in self-defence. The Doctor realizes that the cubes are part of a 'slow invasion'.

While Rory, Amy, and Brian go to the hospital to help those injured by the cubes, the Doctor, Lilith, Rose, and Darkel are summoned to the UNIT headquarters under the Tower of London where Kate shows them several cubes under investigation, every single one behaving in a different fashion. The cubes then simultaneously display the number seven and slowly count down. The cubes all open when they reach zero, appearing empty, but soon reports of people dying from cardiac arrest appear from around the globe. The Doctor finds that one of his own hearts has stopped, and realizes that the cubes sent out an electrical impulse that killed about one third of the human population. Kate's team traces a communication from the cubes to seven different outposts across the world, including one at Rory's hospital, and the Doctor and the girls race there. Rose uses a defibrillator to restart the Doctor's heart. They find the girl, who the Doctor realises is an android, and disable her before locating the elevator and the portal. Aboard the ship, Amy and Rory rescue Brian while the Tyler-Lungbarrows encounter a hologram of a member of the Shakri, who, according to Gallifreyan legend, were self-appointed 'pest controllers' in the universe. The Shakri states that he and six other ships tied to the other outposts are there to wipe out humanity before it spreads across the galaxy, and prepares to launch a second wave of cubes to kill even more before disappearing. The Doctor uses the ship's computer to reverse the shock the cubes gave to the original victims, restoring them, and the seven escape the ship before the feedback from the cubes causes it to explode. As the world recovers, Lilith, Rose, Darkel, and the Doctor prepare to leave when Brian insists that Amy and Rory go with them, stating the adventures they have with him are a once-in-a-lifetime opportunity. He tells the Doctor to "just bring them back safe". The six say goodbye to Brian and depart in the TARDIS.

The Tyler-Lungbarrows, Amy, and Rory enjoy a picnic in New York's Central Park in 2012, with Lilith reading from a pulp novel about a 1930’s detective named Melody Malone. Despite Amy's insistence, Lilith refuses to read ahead to reveal spoilers and tears out the last page of the book. Meanwhile, Rory and Darkel go to get coffee and are sent back to the 1930’s by a cherub Weeping Angel. In the present, Lilith and Amy are shocked to find Darkel and Rory written into the book. Amy insists on reading ahead, but the Doctor warns her that anything she reads will be destined to happen. Instead, they attempt to take the TARDIS back to the 1930's, finding the time machine struggling to make the journey. Rory, Darkel, and River are captured by Mr. Grayle, who has a weakened Weeping Angel in his possession. Mr. Grayle orders Rory and Darkel locked in the cellar with a number of the cherub angels, while he has the Angel grab River by the wrist while he interrogates her. River is able to use her vortex manipulator to set a beacon for the TARDIS, allowing the Doctor, Rose, Lilith, and Amy to arrive. Amy, aware of River having written the book to help guide them, uses the table of contents of the book to look for Rory. The Doctor is dismayed when he reads about River's wrist being broken and the title of the last chapter, ‘Amelia's Last Farewell’. He refuses to help River escape, hoping that the future can be changed. However, River breaks her own wrist to free herself, and the Doctor uses his regeneration energy to heal her.

Just as the Doctor and the others arrive, Rory finds an elderly version of himself in the bedroom. The Doctor warns that Rory's fate is now sealed-- he will die in that room, without having seen Amy for a very long time beforehand. He deduces that the Angels have been using the Quay as a battery farm, sending the victims to their past while feeding off their time energy. Rory and Amy refuse to accept their fate, and as the Angels converge, they flee to the roof with Lilith, where the Statue of Liberty, revealed to be a Weeping Angel, waits for them. Rory surmises that if he kills himself by jumping off the roof, he'll create a paradox that will destroy the building and the Angels, resetting the future. Refusing to allow him to die alone, Amy and Lilith join him and the three jump off the roof. The Doctor, Rose, Darkel, Lilith, River, Amy, and Rory suddenly find themselves near the TARDIS in a New York graveyard back in 2012, Rory's plan having worked. As the four prepare to depart, Rory catches sight of a tombstone with his name on it. He is then touched by a surviving, albeit weakened, Angel and sent into the past. The Doctor is unable to take the TARDIS back to get him, due to the paradox Rory, Amy, and Lilith created. Amy refuses to be parted from Rory and makes Lilith swear to look after River and make sure she doesn’t do anything “stupid” before willingly allowing herself to be touched by the same Angel in the hopes of being sent back to the same time as he was. Her name then appears along with Rory's on the tombstone. Lilith is distraught, but River reminds her that while their fates are now sealed, Amy likely published the Melody Malone book in the past and may have left them a message. The family races back to where they had their picnic and Lilith recovers the final page, finding the afterword written by Amy to her and the Doctor. Amy explains that she and Rory lived out a good and happy life for themselves, and asks them to visit her childhood self to assure her that they will come back for her to take her on amazing journeys.
