Travels with the Eleventh Doctor
When the Doctor returned for her, Clara was waiting eagerly. She rushed to meet the TARDIS outside the moment the Doctor knocked on her door. When the Doctor asked her where she wanted to go, she was stuck at first. She quickly recovered, replying "somewhere awesome". He took her to the Festival of Offerings near Akhaten.
There, they explored the markets and watched the festival. When Merry Gejelh, whom Clara had comforted and encouraged to sing the Long Song at the Festival, was taken by the Mummy, Clara and the Doctor saved her. In doing so, Clara had to give up her mother's ring, which had extreme sentimental value to her. To destroy Akhaten, she was forced to sacrifice something even more precious: the leaf that brought her parents together, "the most important leaf in human history". After saving everyone on the planet, they thanked her by returning her ring. After the trip, the Doctor dropped her back off at her house in London, which she remarked looked different.
The Doctor later took her on another trip, but instead of landing in Las Vegas as planned, they landed on the Firebird, a Soviet submarine at the North Pole in 1983. While the Doctor brought the sinking submarine to safety, the TARDIS activated its Hostile Action Displacement System and it dematerialised, leaving the Doctor and Clara on the submarine.
They quickly found that the Ice Warrior Grand Marshall, Skaldak, had been brought on board. The Doctor attempted to convince the submarine's crew to be peaceful to him, but Lieutenant Stepashin stunned Skaldak with a cattle prod. The Doctor ordered the crew to imprison Skaldak; Clara was sent to try and talk some sense into him, under the Doctor's guidance, but discovered Skaldak had managed to escape his capture and threatened to launch the submarine's nuclear missiles. The Doctor and Clara managed to make him hesitate his decision, and Skaldak and the submarine were rescued by an Ice Warrior ship. Skaldak left and remotely disarmed the submarine. The Doctor then confessed to setting the HADS, and found that it had sent the TARDIS to the South Pole; he had to ask the submarine captain for a lift, much to Clara's amusement.
At some point, Clara went to Baghdad in 1930 with the Doctor, where she met and befriended Amy Johnson. After an adventure, Clara bade a sad farewell to Amy, knowing that she wouldn't see Amy again until Amy's death. She soon found a loophole in that her body was never found and, thus, as Amy was drowning a few years later, the TARDIS materialised around her. The Doctor and Clara took Amy to Cornucopia.
Later, the Doctor took Clara to Caliburn House, the home of Major Alec Palmer, which was thought to have been haunted by the "Witch of the Well" for many years. Unknown to Clara, he took her there to speak to the psychic Emma Grayling and find out what Clara was. The Doctor took lots of photographs of the ghost throughout Earth's timeline. The Doctor used his photographs to explain that the "ghost" was, in fact, a time traveller from the future called Hila Tacorien, who was trapped in a pocket universe and being chased by the Crooked Man. The Doctor used a crystal from Metebelis III to make Emma open up the portal to the pocket universe. Whilst there he saved Hila but got trapped himself; Clara argued with the TARDIS voice interface when the TARDIS would not let her in, Clara wanting to use the TARDIS to save the Doctor while the TARDIS was concerned for its own safety.
Later, after revealing that Hila was a distant relative of Alec and Emma, the Doctor realised that the "Crooked Man" in the pocket universe was trying to get to another creature in the house, so he and Clara went back to pick it up.
While the Doctor was out, the TARDIS demonstrated her antagonism toward Clara by deleting her bedroom and creating a holographic leopard while she was in the bathroom. It also created multiple versions of Clara simply to annoy her. After this, he and Clara made an arrangement: he would pick her up every Wednesday and they would have adventures, but unlike his previous companions, she wouldn't travel aboard the TARDIS on a permanent basis as she had responsibilities on Earth of being a nanny.
Timelines in the TARDIS
While trying to teach Clara how to operate the TARDIS, the time machine was caught in a magnetic hobble-field from a space salvage ship, operated by the Van Baalen Bros. A future version of the Doctor arrived through a time rift, throwing his present self a magno-grab remote with "BIG FRIENDLY BUTTON" branded into it to stop the ship's magno-grab. After the Doctor pressed the button, the TARDIS disappeared, escaping the Van Baalens and preventing its engine failure. The Doctor said aloud to Clara that two days had been compressed into the space of one. The Doctor asked Clara if she felt safe travelling with him, and after a long conversation, she admitted that she did.
In an alternate timeline, however, the TARDIS was successfully captured by the Van Baalen Bros., causing the TARDIS to leak the past and future. In the confusion, the Doctor made it out of the TARDIS, while Clara ended up lost inside, her hand burnt by the scorching metal of a magno-grab remote that had mysteriously appeared in the TARDIS and rolled towards her shortly before she was separated from the Doctor. Inside, she travelled through the TARDIS' rooms, running away from a time zombie threatening to harm her. She eventually arrived in the TARDIS library and hid there. She read a book called The History of the Time War, and found out the Doctor's true name.
She kept travelling inside the TARDIS, eventually arriving in an echo of the control room. She was pulled through to another echo room and reunited with the Doctor, meeting Bram and Tricky Van Baalen. The Doctor switched off the countdown to the TARDIS's non-existent self-destruct sequence but realised that the magno-grab had caused the engine to start malfunctioning. On the way to the "centre of the TARDIS", the four kept running from the time zombies and reached the Cloister Room, where they found out what the time zombies really were: them. The Doctor managed to trick the time zombies and make them fall to their deaths inside the Eye of Harmony. The Doctor and Clara ran to the heart of the TARDIS. There, the Doctor told Clara about her uniqueness, and about her multiple lives and deaths.
The Doctor found that the burn marks on Clara's hand had formed words: "BIG FRIENDLY BUTTON". The Doctor then realised they needed to go back to the point of the disaster and activate the magno-grab remote, which had caused the burn marks on Clara's hand before, to stop the field and prevent the disaster. The Doctor passed through a time rift to give the device to his past self, who successfully activated it, undoing the damage to the engine and making Clara forget about the Doctor's name. The Doctor did not want Clara to go searching for his name, because an important secret was connected to it. This adventure, although negated, was later recalled by Clara when the TARDIS leaked time energy.
Continued Adventures
The Doctor and Clara travelled to 1893 Yorkshire and reached a new little town, Sweetville, run by Winifred Gillyflower and her mysterious partner. While investigating the town, the two were taken by Gillyflower's guards into a creepy dungeon, where they were lowered down into a strange red liquid — known locally as "the Crimson Horror". Clara was successfully preserved by the matter and was placed with another survivor into a glass dome in one of the Sweetville houses, awaiting the next part of Mrs Gillyflower's insane plan. After Jenny Flint rescued the Doctor from being held by Ada Gillyflower in an almost catatonic condition, they eventually found Clara. The Doctor broke the glass, took Clara out and pulled her out of her "puppet" condition. Clara, the Doctor and Jenny set off to finally defeat Mrs Gillyflower in a tower in the town; Gillyflower, along with her mysterious partner — the repulsive red leech, Mr Sweet — planned to fire a rocket that would spread the "Crimson Horror" all around the world, wiping humanity out except for those preserved by being lowered into the liquid. Clara broke a chair on Mrs Gillyflower's control console preventing her from triggering the rocket. After the Crimson Horror was safely removed from the rocket, Mrs Gillyflower threatened to kill the Doctor and Clara anyway. She was shot by Strax and fell to the ground, suffering fatal injuries. Mrs Gillyflower died and Mr Sweet was also killed by Mrs Gillyflower's daughter, Ada.
The Doctor brought Clara back to the 21st century to the Maitland family house. Angie and Artie, the children she looked after, found photos from her adventures with the Doctor on her laptop and found out that she was a time traveller. When going through the photos, Clara saw one of her past lives, Clara Oswald, in Victorian London. Realising that both her physical appearance and where the picture took place in was different, Clara began to suspect something wasn't right. Before she could process the thought entirely, the kids begged her to take them to an adventure, or else they would tell their father that their nanny was a time traveller. Clara, lacking any other choice, agreed.
The Doctor took Clara, Artie and Angie to the abandoned theme park, Hedgewick's World of Wonders, where Angie and Artie were taken by the Cybermen, who had been reawakened from their tombs after being presumed long-extinct. The Doctor put Clara in charge of the punishment platoon to fight the Cybermen and began a game of chess to end the stalemate over his mind with the Cyber-Planner, Mr Clever.
The Doctor released the children in exchange for one of his chess pieces and pulled in the "local resources" to stop the Cybermen. The missing Emperor, Ludens Nimrod Kendrick Cord Longstaff XLI, revealed himself as having been their short-statured friend Porridge and activated the planet-destroying bomb. This summoned his spaceship, transmatting the humans on Hedgewick's World to safety while the Cybermen were left behind on Hedgewick's World. Porridge proposed to Clara, but she declined. The Doctor returned Clara, Angie and Artie home.
Clara visited Tickle Town with the Doctor and was trapped in a roller coaster. She eventually escaped in the TARDIS.
Together, they met the King of Bones, and visited the avocado seas of Venofax, where they visited an archaeological dig. While the Doctor enjoyed himself, Clara quickly got bored and pressed some buttons on the archaeologists' equipment, accidentally turning off the barrier keeping the site from being flooded by the avocado seas. Nobody got hurt, but the entire expedition was ruined and everyone got wet.
After leaving Venofax, Clara changed into dry clothes in the TARDIS. When she came out, the Doctor had landed in Dallas in 1963. Clara and the Doctor discovered a parasite called the Shroud which was feeding off of the grief of the assassination of John F. Kennedy. After allying with some clowns from the planet Semtis, the Doctor took the Shroud to Venofax and trapped it there.
Sometime later, whilst at home with Angie and Artie, Clara received a letter from Vastra laced with a soporific that took her into a "conference call". There, she learnt that the murderer Clarence DeMarco had said "The Doctor has a secret, you know. He has one he will take to the grave. And it is discovered," and showed Vastra the co-ordinates to where the Doctor's tomb was. The call was interrupted by the Whisper Men attempting to murder Jenny. River woke up Vastra and Strax, and the Great Intelligence appeared, using the face of Walter Simeon, to tell Clara that to save his friends, the Doctor had to come to Trenzalore - the place of his grave. When she woke up from the conference, River stayed connected. Using the telepathic circuits to get the co-ordinates, the Doctor and Clara went to Trenzalore, crossing the Doctor's timeline. The Great Intelligence was waiting there and wished to enter the tomb of the Doctor, a future, decaying version of the TARDIS.
Entering the decaying TARDIS through a hidden passageway, Clara began to remember the events of a deleted timeline, in which the Doctor told her about her multiple lives, causing her to panic slightly. They eventually made their way to the Doctor's tomb, where the Great Intelligence demanded the Doctor tell him his true name. When he refused, River uttered it, and the door opened. Inside the tomb, the Intelligence entered the Doctor's timeline, rewriting his history, changing all his victories into losses. The universe began decaying, all the people and civilisations saved by the Doctor now destroyed. With no other choice, Clara did what she was meant to do, saying, "Run. Run you clever boy, and remember me", she walked into the timeline as well, scattering herself across time and space. This action projected her across time, creating many other versions of her that saved the Doctor time and time again. Meanwhile, the Eleventh Doctor decided to jump into the timeline as well in order to save her. Hearing the Doctor's comforting voice, she approached him. As they were just about to leave, Clara noticed an incarnation of the Doctor that she'd never met. This version was the only one to break the promise of the name "the Doctor". However, the stress of the experience caused Clara to faint, so she didn't find out anything more about this incarnation. Clara and the Eleventh Doctor then departed, with the mysterious Doctor watching them leave.
After she escaped the Doctor's timeline, Clara could only remember bits and pieces of her echoes' lives. Some memories were more vivid, others she only recalled as dreams.
Hanging out into space from the TARDIS, Clara and the Doctor found a Tonnchenform, similar to Earth tardigrades. The Doctor told Clara that because the space between galaxies was so big, they were rarely seen, but each of the billions of macroscopic creatures out there were beautiful and unique, just like the trillions of microscopic ones on Earth. Soon after, they went on an adventure involving a dinner with alien robots, a small jewel-encrusted seashell stolen by Bozzi the Mysterio, and a chase across the snowscapes of Halas Four.
After the two had ended the Frogman civil war, they were assaulted by Adam Mitchell who abducted Clara and placed her, along with all of the Doctor's other companions, in a suspended animation chamber. The companions were soon freed by Frobisher to fight off the Master's Auton army, with the Doctor delighting in introducing Clara to Amy Pond and Rory Williams before Adam sacrificed himself to thwart the Master's plan. Along with the other companions, Clara attended Adam's funeral before she and the Doctor resumed their travels.
One day, Clara awoke in a darkened and abandoned TARDIS, discovering herself to be in a spatial loop. Finding a button with a note that read "Do Not Touch", Clara decided that it was reverse psychology and pressed it, plummeting into a white void where she was rescued by the Sky Jack and taken to Tipperary Station, a meeting point of several alien scavengers, where she reunited with the Doctor, who had been there for three years from his perspective. As the two conversed, the Doctor came to the realisation that they were still in the TARDIS, within an old console room whose preparations had been comically exaggerated. Arriving at the console, the Doctor explained that this was the machinations of "the Hypothetical Gentelman", a disembodied entity that resided within the TARDIS' Matrix that the Doctor presumed to be a digital copy of a Time Lord tyrant, only for the being to reveal that it was the Matrix. After the Matrix explained how it became sentient, Clara, knowing that the Doctor was telepathically linked to the Matrix, took the initiative and stowed away on its craft, sabotaging it before the Matrix could cross the wormhole into the wider universe. The delay was enough for the Doctor to reset the TARDIS and trap the Matrix in a never ending wormhole. After the aliens had all been returned home, Clara and the Doctor joined the crew of the Sky Jack at VJ Day in the Hawaii.
The Doctor later took Clara to Deadwood in 1882 where they crossed paths with Oscar Wilde and ran afoul of the Doctor's old foe Es'Cartrss who had put Earth on trial. As Clara worked with Calamity Jane, they discovered that Wild Bill Hickok and many others were being resurrected. After thwarting this scheme, the two went off to Shoreditch.
After a particularly stressful day of nannying, the Doctor took Clara to Cui Palta to relax only for both to fall victim to the psychic pollen of the local flowers, hallucinating an elaborate maze before Clara deduced the truth. Despite the danger, Clara was left exhilarated by the experience.
Becoming a Teacher
Once George Maitland was coping well enough on his own, Clara took a teaching job at Coal Hill School. She attended teaching school before taking the job, where she met fellow teacher Christel Dean. She then received the job offer shortly after becoming qualified, perhaps with the Doctor's help.
When she started at school, Clara temporarily said goodbye to the Doctor and the TARDIS, so she could live a normal life for a while. Six weeks in, she began to regret this decision.
In at least one lesson, she lost control of the class and tried to use empty threats to make the children behave. This was unsuccessful, and later this memory would help her when facing threats against her in a further adventure.
In one particular lesson, Clara decided to switch things up, proclaiming, "Normal is overrated," and brought her English class outside to teach them about tardigrades, in an attempt to give them a glimpse into the wonders of the universe. Once they got settled on the grass, she instructed them to look up at the sky for ten seconds, then to shut their eyes, count to five, open them again and tell her what they saw.
Clara rendezvoused with the Eleventh Doctor after school some days and was with him when his TARDIS was airlifted by UNIT to the National Gallery. There, Clara met Kate Stewart and consoled the Doctor when he was reminded of the Last Great Time War. She travelled with a Zygon impersonating Kate Stewart to the Black Archive unaware that the scientific leader of UNIT was being impersonated. Using the code scraped into the wall of the Tower of London, Clara activated Captain Jack Harkness' vortex manipulator and escaped the menacing Zygons by travelling to 1562. There, she met the War Doctor, Tenth Doctor and Queen Elizabeth I and attended the wedding of the latter two.
She was inserted into the Gallifreyan stasis cube Gallifrey Falls No More with the Doctors to surreptitiously re-enter the Black Archive in the 21st century. When the War Doctor left for his own time to activate the Moment, Clara told the two remaining Doctors that she could see in his eyes that the ending of the Time War was still in the earlier incarnation's future. She travelled through the Time Lock with the Doctors and begged them to reconsider when they decided to cause the genocide together. They took this advice to heart. She was therefore present when the Doctor changed history as he remembered it, and saved Gallifrey instead of destroying it. Back on Earth, she briefly met the mysterious Curator, unaware that anything was extraordinary about him. She bade farewell to the past Doctors, and kissed her Doctor on the cheek; when the Doctor asked how she knew he needed time alone with the painting, she told him, "I always know." Clara visited the Black Archive twice, but only had a memory of visiting once. As a result of the visit that she did not remember, she already had security access during the visit she did remember.
At some point, Clara took tae kwon do lessons with the year sevens after school.
On her travels with the Doctor, Clara was attacked by a mind parasite that was dubbed Waites. Waites caused Clara to live a horrible life where she lost her job and all her money but she retained enough awareness to seek out the Doctor, who called himself "John Smith" within the shared dream, only for him to turn her away. Eventually Clara managed to shatter the illusion, seconds after the Doctor, whereupon she physically attacked the parasite for the hell it had subjected her to before she and the Doctor ripped its avatars off its other victims, killing it. As the two walked away, the Doctor theorised that Clara's self awareness was the result of her having lived multiple lives. Clara smiled that the lack of Doctor was probably what had tipped her off that something was amiss.
Clara visited the Obsidian Mainframe and attended the auction for various creatures. She was with the Doctor when the TARDIS was sold, and the Doctor gained a lot of money. They were then forced to travel "the normal way" to the Cornucopia's airport, where Amy Johnson lived.
Trenzalore
Needing a fake boyfriend as she cooked Christmas dinner for her family, Clara called the Doctor twice while he was orbiting a planet surrounded by the universe's most dangerous enemies. She convinced him to come but was shocked to find him naked, which he fixed for her by putting a holographic filter on her. Clara introduced him to her family, who saw him naked because he hadn't put the filter on them. Learning from Handles that the planet was apparently Gallifrey, Clara and the Doctor travelled there. When the Papal Mainframe arrived, the Doctor made Clara swallow a holographic projector to generate holographic clothes around her. Once on board, they met Tasha Lem who agreed to teleport the two to the planet's surface. There, Clara and the Doctor were surrounded by Weeping Angels.
The Doctor pulled a secret key out of the wig he was wearing and summoned the TARDIS, saving them both. Dressed in proper clothes again, he then flew the TARDIS to the nearby town of Christmas, where they learnt that the town was surrounded in a truth field. Searching for the source of the transmission, the two found a crack in time, and the Doctor realised that it was the Time Lords trying to return to the universe. The Doctor then explained that if he said his real name the Time Lords would return but all hell would then break loose. After learning from Tasha Lem that the planet was Trenzalore, the Doctor had Clara return to the TARDIS. In the TARDIS, Clara inserted a device the Doctor gave her and was returned home, but grabbed onto the TARDIS as it dematerialised again.
Clara returned to Trenzalore three hundred years after she left and found the Doctor middle-aged. The Doctor had been defending Trenzalore from the various threats besieging the planet and revealed to Clara that he had used up all of his regenerations and this would be the end of him. Clara begged him to let someone else take up the job of protecting the planet, but the Doctor refused. Clara watched the planet's brief sunrise with him, during which Handles ceased functioning and the two were invited by Tasha to return to the Papal Mainframe.
There, Clara and the Doctor were led into a trap, as the Daleks had already taken over the Mainframe and converted everyone, including Tasha, into Dalek puppets. When the Doctor threatened to release the Time Lords if the Daleks tried to kill him, Tasha took Clara hostage, and the Doctor claimed not to care if she died. Bravely, Clara declared she would die anyway. Using Clara as an example of bravery, the Doctor helped Tasha regain control of herself and she teleported them back to the planet after disposing of the Daleks.
The Doctor and Clara returned to the TARDIS where they found Clara's turkey cooked, and after promising never to send her away again, he tricked her into returning home once more. As a grief-stricken Clara celebrated Christmas dinner with her family, she had her grandmother repeat the story of how she fell for her grandfather and was relieved to hear the TARDIS returning for her again, grabbing a Christmas cracker to take to the Doctor. To her surprise, Clara discovered Tasha piloting the TARDIS, and Tasha returned her to Trenzalore sometime further into the future after she left, telling her to go find the Doctor.
Upon reuniting with the Doctor, Clara found him very old and weak. While they sat together, Clara opened the cracker and read the poem inside. When the Daleks demanded his surrender, he agreed but asked Clara to remain behind for her own safety. Desperate to change the future, Clara pleaded to the Time Lords for help through the crack. To her surprise, the crack snapped shut disappeared.
Clara watched tearfully as the Doctor stood on top of Christmas' Clock Tower and surrendered to the Daleks, prepared to die at last. As the Daleks hesitated and the Doctor goaded them on, the Time Lords granted the Doctor a new regenerative cycle. To Clara's relief, the Doctor began to regenerate, using the explosive force of his regeneration energy to destroy the Daleks. When the dust cleared, there was no sign of the Doctor, so Clara checked the TARDIS where she found him restored to his youthful self. However, the Doctor told her that he would still regenerate.
She implored him not to change but despite her pleas, the Doctor suddenly regenerated into a new, older incarnation who left Clara confused by staring at her face to face, and then making comments about his new kidneys. The TARDIS suddenly began crashing, and to Clara's horror, the new Doctor asked her if she knew how to pilot the TARDIS, having apparently forgotten how to do so himself.
