The Pilot (TV story)

 was the first episode of the tenth series of Doctor Who produced by BBC Wales. It introduced the Twelfth Doctor's new companion, Bill Potts.

According to Steven Moffat in a video introduction, "series 10 sort of begins the show again. [The Pilot] introduces everything you need to know about Doctor Who, and tips you into the universe". Indeed, through Bill's eyes now, viewers are introduced again to the character of the Doctor, his TARDIS, his enemies the Daleks, and his versatile tool, the sonic screwdriver.

New viewers are brought into the show with all important information given, and meet the Doctor as a mysterious figure, much like they did through Rose Tyler in series 1's 2005 "pilot", Rose, or through Ian and Barbara in the original 1963 introduction, "An Unearthly Child". Much like Rose, The Pilot follows Bill around in every scene.

This was also the first on-screen depiction of Movellans since their debut in Destiny of the Daleks. The episode introduces St Luke's University, where the Doctor apparently has been lecturing for over fifty years, and begins a plot thread surrounding what he and Nardole are hiding in a vault beneath the campus. This bears some similarity to the era of the Third Doctor, who was likewise restricted in his travels and held a job as the scientific adviser of UNIT.

Some things were different with Bill as a companion; she was panicky when first traveling in the TARDIS, and took a long time to figure out that it was time machine that "bigger on the inside". Continuing the unofficial theme of having the Daleks appear in each season of the Revived Series, the Doctor attempts to destroy the sentient oil with the deadliest fire in the universe, which turns out to the Daleks.

By the Doctor's own admission, he has come to believe that if he encounters some kind of alien on Earth, it is likely going to be dangerous as most of the past aliens he's encountered on Earth have been. However, in a twist, the "threat" turns out to be a misunderstanding caused by a crush.

This episode marks the first time since The Snowmen that the lights in the TARDIS have been off. However, unlike back then, ALL the lights are now able to be shut off when the Doctor hasn't been inside for a while.

Synopsis
The Twelfth Doctor — now living and teaching at St Luke's University on Earth — convinces dinner lady Bill Potts to be his private student. The Time Lord and his companion Nardole soon discover that their new friend has unwittingly made a deal with a prospective girlfriend that threatens their safety in a way that even the TARDIS can't outrun.

Plot
The episode opens with an empty university professor's office; nobody is in it. The sounds of mechanical whirring is heard for a brief while before the door opens and Nardole leads a woman called Bill Potts in; he gestures for her to take a seat at the professor's desk. A screw falls off his arm, but he discretely kicks it away before Bill can notice. He leaves without a word, leaving Bill to wait for the professor to arrive.

Bill looks around the room, finding the TARDIS with an "Out of Order" sign handing on it. Noting a mug on the professor's desk full of strange devices, which are screwdrivers, Bill reaches to examine one. However, she is startled by the sound of an electric guitar playing the opening bars to Beethoven's Fifth Symphony. She coughs, getting the professor's attention from the adjacent room; the Doctor sticks his head in, telling Bill he'll be with her in a moment.

Putting his guitar away, the Doctor takes his seat and asks Bill for her name. He wonders why she's at the university. Bill states that she does not go there, but the Doctor counters by telling her that he's seen her attending his lectures. She tells him that she actually works at the university canteen. After fumbling over a story about a woman she fancied in the canteen, Bill confesses that she loves his lectures and always wanted to attend the university. She then challenges back, asking why the man has taken an interest in her as "loads attend [his] lectures". He responds that it is due to the fact she smiles when she doesn't understand something, while the majority frown.

Bill asks around about the Doctor, telling him that it's rumoured he's lectured for 70 years. The Doctor think it's going to be a question about his age, but Bill says it's actually about what subject he's lecturing on. It's seem the Doctor has permission to talk about whatever he wishes; he was going to give a lecture about quantum physics, but then talked about poetry. The Doctor tells her that their basically the same thing because of all the rhyming. He offers to be Bill's personal tutor, stating that she must come to him at 6pm every weekday (even if someone is dying) and if she gets anything less than a First on each assignment, the tutoring will cease. As she leaves, she asks what to call him, as everyone calls him the Doctor. He tells her it's what he's called. Bill is not liking the idea as it's not a proper name; she asks "Doctor what?" The Doctor smiles.

Bill goes through her daily routine: serving chips, attending the Doctor's lecture and tutoring session, and returning home to her foster mother, Moira. Bill explains that the Doctor is kind of her foster tutor, as Moira goes over Bill's tests; Bill gets at least 87% or above in each subject the Doctor taught her, even more obscure subjects. Moira is worried the Doctor might be some kind of pedophile, warning Bill to be careful of men. Annoyed, Bill mutters under her breath she's not interested in men.

The Doctor gives a lecture on the concept of the passage of time; in truth, time doesn't really pass, because life is a great magician that only allows people live days at a time. He further explains that each day is like a photo that doesn't move, much like movies, when played after each other, time appears to move. The Doctor then calls this Time and Relative Dimension in Space, going on to say "it's called life". That night, a blonde woman catches Bill's eye when she visits a bar.

The next morning, Bill follows the Doctor and Nardole, who descend into a hidden vault under the university. She meets Heather, the girl from the previous night, looks distraught. Bill notices a starlike pattern in Heather's eye, but Heather simply brushes this off as a "defect" and expresses, "Everywhere I go, I just want to leave." Heather leads Bill to a mysterious puddle near the university, telling her to look at her reflection in it. Both notice something is wrong with the reflection, but Bill doesn't know what. After the two leave, a voice issuing from the puddle claims that a "pilot is located".

At Christmastime, Bill celebrates with the Doctor, giving him a rug as a present, surprising the Doctor as he hasn't got her anything. They discuss travelling, Bill stating she can sense that the Doctor travels around, even though he denies it, stating "you can smell the wind in people's clothes". She tells him that is what she presumes her birth mother would have said, revealing she died when Bill was young. Bill tells him that she apparently looks like her mother but doesn't have any photos to know this, wondering whether photos really help after loved ones are gone, causing the Doctor to look wistfully at the photos of his wife River and granddaughter Susan on his desk. At home, Bill's foster mother Moira shows her a newfound box containing photos of Bill's birth mother. Bill weeps upon discovering that she looks just like her mother. She notices the reflection in a mirror in one of the photos, the Doctor seemingly being the one photographing her mother.



Bill meets Heather again, but Heather mysteriously disappears while Bill is running around to meet her at the puddle. Bill consults the Doctor, who runs out of his office to investigate the puddle and the scorch marks surrounding it. The puddle seems to mimic a the subject, rather than producing a mirror image; in short, its a reflection of a reflection. The puddles is showing whoever looks into what it sees. The Doctor sends Bill home, where she notices someone in the bath, even though Moira is out that night. Bill runs to the university after noticing Heather's starry eye staring out of her bathroom drain.

Outside St Luke's University, Bill is confronted by the puddle, which has taken on the form of a soaked Heather. Bill rushes into the Doctor's office, where the puddle gushes into the room, reforming into Heather. The Doctor convinces Bill to enter his blue box, taking the sign off as they do. Bill protests that the box can't save them only to turn around as the console lights up and the Doctor reveals the TARDIS. Coming to terms with its size, Bill claims she needs the toilet, meeting Nardole on her way down. The Doctor proceeds to take them down to the vault, where she realises that the police box in the corner of the Doctor's office is his spaceship, which is bigger on the inside. The Doctor and Bill infer that the puddle alien is not here for whatever is hidden inside the vault and is instead there to chase them. They escape in the TARDIS, which the Doctor flies to Australia to test the puddle's abilities.

In Australia, Bill asks the Doctor about his alien origin and the acronym "TARDIS", which wouldn't have made sense in his native language. The Doctor replies that most people don't bring this up. However, the puddle catches up, so the trio leaves to a planet on the other side of the universe, 23 million years in the future. Here, the Doctor and Bill hypothesise that the puddle is a type of sentient oil or perhaps a shape-shifting "liquid spaceship" requiring a host "pilot". Bill remembers Heather's desires to leave, explaining why the alien chose Heather. No sooner do they realise this, but the alien materialises and nearly takes Bill with it. The Doctor's last test of the puddle's abilities is to destroy it in "the deadliest fire in the universe".

Nardole is terrified of where they're going; the Doctor hands him the Fourth Doctor's sonic and tells him to run interference. Once they land, Nardole runs off in the opposite direction. The Doctor leads Bill to where the Dalek-Movellan War is being fought. They are found by Heather, who is shot by a Dalek; the blast goes though her. It keeps firing in vain as the Doctor and Bill run. They are later confronted by a Dalek, which the Doctor realizes Heather in a new form. Heather dissolves and reforms as herself. The Doctor unable to figure out what can defeat it, Bill remembers that Heather promised not to leave her behind before the puddle absorbed her. "Never underestimate a crush" the Doctor notes; he tells Bill to release Heather from the promise to let her be at pace. Bill sadly absolves Heather of this promise, but the alien tries to entice her anyway by using Heather's memories of the mutual attraction between her and Bill. The Doctor tells Bill to resist, and Bill sadly says good-bye to Heather. Heather also sadly says good-bye and dissolves.

The Doctor brusquely returns to his ship while Nardole comments on the former's seemingly ignorant behaviour. Bill comments that the tears she sheds don't feel like her own.

Back in his university office, the Doctor tells Bill that she must forget about seeing Heather or travelling in the TARDIS and tries to wipe her memories of doing so, explaining that he must remain in disguise, unknown to everyone due to a promise he made. Bill retorts, asking how the he would feel if someone tried to wipe his memories. The Doctor tells Bill to leave immediately without another question before he changes his mind. He looks at the picture of River, telling to shut up, then the same for Susan's picture. Even the TARDIS briefly hums causing the Doctor to confess he "can't keep doing this".



Bill finds the Doctor next to his TARDIS on the university courtyard. The Doctor tells Bill that he changed his mind. When she asks what caused him to, the Doctor responds "Time and Relative Dimension in Space. It means what the hell." Happy, Bill runs into the TARDIS, followed by the Doctor who shuts the behind them. Now the Time Lord is ready to see the universe anew.

Story notes

 * A working title for this episode was A Star In Her Eye.
 * Before filming started, a two-minute scene featuring the Doctor and Bill known as Friend From the Future was broadcast in April 2016, set during the encounter in the Dalek war zone. Parts of this scene were adapted into the episode. (DWM 511)
 * The read-through for The Pilot took place on 14 June 2016, and filming on the episode began on 20 June.
 * The song "Love Will Tear Us Apart" by Joy Division plays during the bar scene, when Bill and Heather first meet.
 * Bill mentioning people being possessed by lizards in the brains is a reference to the series Stargate.
 * When the Doctor finally invites Bill onboard the TARDIS, he says "Time And Relative Dimension In Space, it means... what the hell." it is a reference to the scene in Back to the Future in which Doc Brown tells Marty he broke the space-time continuum by avoiding death.
 * During the scene in which the TARDIS travels to the Dalek-Movellan War Zone, a short scene from TV: The Doctor's Wife is re-used in which the TARDIS leaves through the bubble universe rift for the House planetoid.
 * As described by Caroline Lie, many if not all of the extras who attend the Doctor's lecture were employees from Doctor Who Experience in Cardiff. She can be seen, in fact, in multiple places, often near her friends, including Joe (TARDISArchives). Both previously participated in Classmates, a YouTube series consisting of fan reactions to episodes of Class.
 * The setting of this story bears some resemblance to the unfinished TV story Shada. Both stories feature Time Lords (in Shada, Chronotis; in The Pilot, the Doctor) who settle in colleges as eccentric professors for an extended period of time. Both feature opening shots of a student (in Shada, Chris Parsons; in The Pilot, Bill Potts) entering their studies and noticing the TARDIS, parked in the corner.
 * During the scene when the Doctor is about to wipe Bill's memory and she tells him to imagine if someone did it to him, "Clara's Theme" plays. This is a reference to the events of TV: Hell Bent.
 * "The Sad Man with A Box" plays in the scene in which Bill is introduced to the TARDIS. A happier, more fairy-tale rendition of this same tune, "The Mad Man with a Box", played during the scene in The Eleventh Hour when Amy walked into the TARDIS and saw the interior for the first time.
 * The Doctor uses a chalkboard with the same white roundel frame in his university classroom as Miss Quill does in her classroom at Coal Hill Academy in the spin-off Class.
 * The romance between Bill Potts and her friend, Heather, may be homage to William "Bill" Hartnell, the first actor to portray the Doctor, and his wife, Heather Hartnell.
 * The ringtone for Bill's mobile phone is the same as the one for Martha Jones' phone, which was later kept onboard the TARDIS by the Tenth Doctor.
 * When Nardole shows Bill the Doctor's office, his arm makes a mechanical sound and a bolt falls from it, implying that his body is robotic, or at least partially cybernetic.
 * Pearl Mackie is added to the title sequence in place of Jenna Coleman and is immediately followed by "and Matt Lucas", bridging the gap between actor names in the previous episode. The Doctor's face also appears after the show's title now.
 * According to Doctor Who Magazine #512, two scenes were filmed, but edited out before broadcast. One features Bill asking Nardole about the Doctor; the other was an alternate edit of the club sequence where Bill meets Heather for the first time. As originally filmed, Bill was to be shown watching the Doctor, on stage, sadly playing Clara's Theme. The only remnant of this in the final episode is a brief glimpse of the neck of the Doctor's guitar and his left hand.

Myths and rumours

 * The episode was to include a "very mild" sex scene between Bill and another character. This rumour circulated widely on Twitter in the months prior to broadcast, allegedly citing an advance copy of the episode and emerged in conjunction with the (later confirmed) rumour that Bill would be gay. There is no indication such a scene was ever actually scripted or filmed.
 * The character of Bill and Heather, who become attracted to each other, are named for William Hartnell and his wife, Heather. Steven Moffat has confirmed that this was a coincidence.

Ratings
The overnight ratings on BBC One were 4.64 million, up 60,000 viewers from the previous series opener, The Magician's Apprentice. Consolidated figures were 6.68 million, the highest figures for a standard series episode since the Series 8 finale, Death in Heaven.

Filming locations

 * The Main Building, the Sir Martin Evans Building, and Tower Building of Cardiff University largely fill in for St Luke's University, while the Reardon Smith Theatre (within the National Museum of Wales) is where the Doctor gives his lectures.
 * The Cardiff Metropolitan University (Llandaff Campus)'s Atrium Cafe is where Bill serves chips.
 * The bar scene was shot at Clwb Ifor Bach in Cardiff.
