Flatline (TV story)

Flatline was the ninth episode of the eighth series of Doctor Who produced by BBC Wales. For scheduling reasons, it was a "Doctor-lite" episode.

Flatline was Jamie Mathieson's first script for the show. Two years before writing it, he had pitched his ideas for a story to Steven Moffat, but was unsuccessful. When he again met with the executive producer, he showed him four ideas for episodes, complete with his own illustrations, aided by his background in art college. Taking an interest in the monster he had created for what would become Flatline, Moffat asked Mathieson to produce a story outline and he got the job to script the episode.

It was only after writing several drafts that he was told the episode would need to lock the Doctor away in a single location, as Peter Capaldi’s scenes for the episode needed to be filmed quickly to bide by the production schedule.

Mathieson decided to write a script where the Doctor was "in the dark". For this to be successful, he had to create a unknown quantity to feature as his alien enemy. Much like his next creation, the Foretold, he elected to have no dialogue for the aggressors, allowing  something about them to remain "unknowable". (DWM 479)

Synopsis
In a council estate, Clara takes charge as beings from another dimension threaten the Earth...

Plot
The Doctor misjudges location when returning Clara to the present day, resulting in them landing in Bristol rather than London. They also discover that the exterior of the TARDIS has shrunk down due a mystery power draining nearby; the Doctor stays with the smaller TARDIS to figure out what is going on while Clara looks around. She finds that locals are disappearing, and mystery murals of them painted in a nearby pedestrian tunnel. Clara returns to find the TARDIS' exterior has shrunk further, trapping the Doctor within as he is unable to fit through the miniaturised doors. He hands Clara his psychic paper, the sonic screwdriver, and an audio/visual earpiece so he can keep in touch with her, and then has her carry the TARDIS with her to where he has tracked a large source of energy.

Clara poses as "Doctor Oswald" and gains the confidence of a local graffiti artist, Rigsy, who is part of a community service team, despite the Doctor's initial hesitation towards him. After finding nothing but a strange desert mural at the flat of the latest disappearance, Rigsy gains help from a police officer to gain access to the flat of the first known missing person. The Doctor instructs Clara to tear out the walls, believing the energy source to be within them. While they work, PC Forrest is sucked into the ground out of view of Clara and Rigsy, and when they reach her screams she has disappeared. They look around the room and find another strange mural, and the Doctor realises it's likely to be PC Forrest's nervous system, and believes the first mural was a closeup of human skin of the latest victim. As the entities start to move towards Clara and Rigsy, the Doctor quickly explains the creatures are two-dimensional, and must have been experimenting on the three-dimensional world. As Clara and Rigsy try to avoid the entity, which is in the walls and ground, Danny phones Clara, and she manages to avoid questions of her whereabouts and quickly hangs up. The Doctor, who is listening in, recognises that Clara has lied to him about Danny accepting her continued travels in the TARDIS.

Clara and Rigsy return to the rest of the community service group, who are about to paint over the murals in the pedestrian tunnel. The Doctor realises that the images are masquerades for the two-dimensional creatures, attempting to understand three dimensions; after the creatures take one of the services workers, Clara leads the rest away with the creatures chasing them. They take shelter in a nearby engine repair warehouse, where the Doctor helps Clara to try to communicate with the creatures using mathematics. When another worker is taken, Clara and the surviving members flee into a disused subway tunnel. As they explore, they find their only escape route has been flattened to two dimensions by the creatures. The Doctor provides Clara with a device to restore the dimensions, and they just manage to escape. However in the chaos, the TARDIS is shrunk further and falls down a shaft on to an active railway line. The Doctor activates the TARDIS' siege mode to protect it from an oncoming train, but without power is unable to return it to normal.

Clara uses the sonic screwdriver to stop an out-of-service train, and they attempt to ram the creatures to prolong time to get back in contact with the Doctor. However, the train is simply transformed into two dimensions; as they escape, Clara finds the TARDIS now looking like a plain Gallifreyan cube, and takes it with her. Taking shelter in a disused office space, Clara comes up with a plan to provide energy to the TARDIS by having Rigsy paint out a fake access door on the back of a large poster, so that when the creatures attempt to pull it into three dimensions, they instead feed their energy into the TARDIS, restoring it to normal. Realizing they have no interest in peace, the Doctor uses the sonic screwdriver to stop the creatures, whom he dubs the "Boneless", sending them back to their dimension with a warning to those who survive the trip to never return. The Doctor returns everyone to the surface safely. Clara rejects a call from Danny, catching the Doctor's attention; he notes that she enjoyed 'playing the Doctor' for the day.

Missy, seated in a darkened room, is watching Clara on what appears to be a tablet. The insinuation is that Missy has watched the events of the serial unfold. Missy says that with regard to Clara that she has "chosen well".

Production errors

 * The Doctor's hair is noticeably shorter in several scenes, starting when the TARDIS falls onto the train track.
 * In the TARDIS when Clara asks the Doctor to come and see the shrunken TARDIS door the scanner is in the right side of the TARDIS while before it was in the left side.
 * The hammer the Doctor hands Clara has a head too big to have fit through the shrunken TARDIS' door.
 * When the TARDIS was first small, the Doctor used one door to get out due to a lining in between in the doors. The second time the TARDIS was very small, both doors were open with there being no lining in between the doors.
 * The distance between the shrunken TARDIS and the tracks decreases. It is a safe distance from the tracks as the Doctor was climbing the dirt hill with his fingers, then it appears a little closer to the tracks the next scene when he pulls his hand in, the next scene, it is close enough that when it topples over, the top is laying on the tracks.

Continuity

 * The TARDIS exterior has shrunk on previous occasions:
 * When the TARDIS doors opened during flight, it was made smaller upon materialisation, as the were the First Doctor and its other occupants. (TV: Planet of Giants)
 * While the Fourth Doctor pursued fixing the chameleon circuit, the TARDIS was reduced in size after interfered with the Logopolitan's Block Transfer Computation. (TV: Logopolis)
 * The Doctor again uses "pudding brain" as a mocking description of humans and their intelligence. (TV: Deep Breath)
 * The Doctor uncovers Clara's lies about Danny's stance on her travelling with him. (TV: Mummy on the Orient Express)
 * Isolus and the Mona Lisa were able to transfer the two dimensional into the three dimensional, and vice versa. (TV: Fear Her, Mona Lisa's Revenge)
 * There are people naturally immune to the psychic paper. (TV: The Shakespeare Code)
 * The Doctor is uncomfortable with how easily Clara assumed his role. Previously, Davros and Rory, in different ways, noted the Doctor's tendency to turn his companions into reflections of himself. (TV: Journey's End, The Girl Who Waited)
 * The question of whether the Doctor is "a good man" is revisited, as he says of Clara's success in his role, "goodness had nothing to do with it." Before the Time War, the Eighth Doctor believed he was (TV: Night of the Doctor). At Demon's Run, the Eleventh Doctor clearly believed otherwise (TV: A Good Man Goes to War). Previously, the Twelfth Doctor had been unsure himself (TV: Into the Dalek)
