Hide (TV story)

Hide was the ninth episode of the seventh series of Doctor Who produced by BBC Wales.

It saw the Doctor continue his investigation into Clara Oswald's true nature and saw her directly communicate with the Doctor's TARDIS for the first time, leading into the subsequent episode.

Synopsis
Clara and the Eleventh Doctor arrive at the haunted Caliburn House, set alone on a desolate moor. Within its walls, a ghost-hunting professor and a gifted empathic psychic are searching for the Witch of the Well. Her apparition appears throughout the history of the building, but is she really a ghost? And what is chasing her?

Plot
"Caliburn House. Night four. November 25th, 1974. 11:04 pm."

Professor Alec Palmer and his assistant Emma Grayling are attempting to contact an apparition haunting Caliburn House. Emma is a psychic, and uses her gifts to gain the attention of the "ghost". They are interrupted by knocking at the front door, and open it to find the Eleventh Doctor and Clara. The Doctor tells Alec that he is looking for a ghost and Clara claims that they are "Ghostbusters".

The Doctor claims to be from "the Ministry", and knows who Alec and Emma are. Photographs taken by the professor show the same figure in the same pose throughout the history of Caliburn House. The Doctor and Clara search the house, as a strange creature stalks them through it. Loud knocking is heard, which is said to be associated with the "Witch of the Well".

The Doctor returns with Clara to the TARDIS and takes a series of photographs of the "ghost" throughout Earth's timeline. Upset at seeing Earth become a lifeless rock, Clara believes that she is nothing more than a ghost to the Doctor, because as a time traveller he has been to a time when she is long dead. He tells her that she is "the only mystery worth solving". The Doctor uses his photographs to explain that the "ghost" is in fact a time traveller called Hila Tacorien, who is trapped in a pocket universe in the process of collapsing and being chased by an unknown creature.

The Doctor uses a crystal from Metebelis III to enhance Emma's thoughts and use them to create a portal to the pocket universe, a reality "well". He goes to rescue Hila, who escapes, but is trapped in the pocket universe with the monster after Emma collapses. As the professor encourages Emma to try again - finally admitting he loves her - Clara returns to the TARDIS, and after a brief argument with the voice interface (which appears as herself, much to her annoyance), manages to break into the pocket universe and rescue the Doctor from the creature.

The next morning in conversation with Emma, the Doctor reveals that he brought Clara to Caliburn House in order to see Emma, not the ghost. He asks what she senses about Clara, but Emma reports nothing unusual about her. As the Doctor and Clara are preparing to leave, the Doctor inadvertently reveals that Hila is Emma and Alec's future descendant. Alec and Emma are in love, and the Doctor advises them to "hold hands, and don't let go". Then the Doctor realises that the creature in the pocket universe has been trying to return to another creature in the house. He then states that every lonely monster needs a companion, and explains to Clara that the two creatures have been separated through time and space and certain events, and are yearning to be with one another. He describes this as not a "ghost story" but a "love story". He then returns to the pocket universe, where he reconciles with the monster to bring it back in the exact same manner as before.

Cast

The Doctor

 * When the Doctor introduces himself, Alec asks him, "Doctor what?," to which the Doctor responds, "If you like."
 * The Doctor says he loves carrier pigeons.
 * Emma tells Clara not to trust the Doctor, saying that "he has a sliver of ice in his heart".

Individuals

 * Alec is a ghost-hunter, as well as a "member of the Baker Street Irregulars [who] specialised in espionage, sabotage and reconnaissance behind enemy lines, a talented water colourist [and a] professor of psychology."
 * Emma is an empathic psychic and assistant to Alec.

Popular culture from the real world

 * Clara introduces herself and the Doctor as "Ghostbusters." The Doctor and Rose sang this song earlier in Army of Ghosts.
 * The Doctor quotes the song Let's Do It (Let's Fall in Love) by Cole Porter when he realises the truth about the two monsters ("Birds do it, bees do it - even educated fleas do it!").

Foods and beverages

 * The Doctor drinks milk.
 * Emma and Clara both have a glass of whiskey which they don't like, and so drink tea instead. Furthermore, Clara calls whiskey the "11th most disgusting drink ever invented."
 * The Doctor requests some Kendal Mint Cakes to go with his Tacorien rescue.

Places

 * Alec owns Caliburn House, which was built sometime before 1474.
 * The "Cumbrian agenda" of series 7b continues in this episode with not only the positive reference to Kendal Mint Cakes, but also the negative one to Carlisle being the "opposite of bliss".

The TARDIS

 * Clara calls the TARDIS a "grumpy old cow."
 * The TARDIS uses her voice visual interface to talk with Clara, using a hologram of Clara herself, because the interface is programmed to "select the image of a person you esteem." Unlike the last time the Doctor used a similar interface, (TV: Let's Kill Hitler) the TARDIS projects the interface outside of the ship and, for the first time on screen, addresses a companion in this manner.
 * The TARDIS unlocks herself in order to allow Clara to enter, even though she doesn't yet have a key.
 * Clara says that they need a place to keep her umbrella, the Doctor states that he has or had a place at one point. The First, Second, Fourth, Fifth and Seventh Doctors all had umbrella racks in their control rooms, and the Fifth, Ninth, Tenth's control rooms, as well as the Eleventh's first one, had hat stands.
 * It is revealed that the TARDIS is capable of piloting herself, at will, even into challenging locations where her existence is threatened. This supports the contention made in The Doctor's Wife that she often guides the Doctor to where he needs to go.

Technology

 * The Doctor obsesses over toggle switches and an ACR 99821.
 * A subset of the Eye of Harmony is used to open a gateway to the pocket dimension.
 * Alec has a Kodak Carousel S projector.
 * The Doctor builds a psychochronograph.

Story notes

 * Working titles for the episode were Phantom of the Hex and The Hider in the House.
 * The read-through for this episode took place on 21 May 2012, and filming began on the 24th.
 * Scriptwriter Neil Cross confirmed that the episode had been inspired by Nigel Kneale's acclaimed 1972 TV play The Stone Tape, also about a scientific investigation of a haunted house with a psychic as one of the team.
 * Hide was the first episode filmed by Jenna-Louise Coleman as a series regular, but screened as the fourth episode in series 7b.

Continuity

 * The Doctor is able to utilise a "subset of the Eye of Harmony" to enter a pocket universe by running cables from the TARDIS. (TV: The Deadly Assassin, Doctor Who)

 * Clara references the Eleventh Doctor's big chin, as had previously Oswin Oswald. (TV: Asylum of the Daleks)
 * The Doctor uses a blue crystal from Metebelis III in order to amplify Emma'spowers (but pronounces it very differently to his predecessor ("Me-TEB-eh-lis" instead of "Met-a-BEE-lis"). (TV: The Green Death, Planet of the Spiders, AUDIO: Worldwide Web)
 * Emma speaks to the ghost, telling it to "speak to me," in the same vein as Gwyneth holding a séance and saying "speak to us." (TV: The Unquiet Dead)
 * The Doctor enters a pocket universe. (TV: The Celestial Toymaker, The Mind Robber, Full Circle, The Doctor's Wife, et al.)
 * The Doctor uses what appears to be the same reddish-orange space suit he used on Krop Tor (TV: The Impossible Planet) and Mars (TV: The Waters of Mars). If this is true then The Doctor removed the "Sanctuary Base 6" logo at some point.

 * Sarah Jane Smith once visited a haunted house very similar to this. (TV: ''The Eternity Trap)
 * The Fourth Doctor previously encountered a time traveler from the future, whose journey had gone disastrously wrong. (TV: The Talons of Weng-Chiang)
 * The Doctor previously drew a symbol on the floor with chalk to solve a problem from another pocket universe. (TV: Battlefield)
 * Both the Doctor and the TARDIS state that the pocket universe would drain the energy from the TARDIS; this had previously happened in a parallel universe, requiring the Tenth Doctor to give up ten years of his life to "recharge" the TARDIS. (TV: Rise of the Cybermen/The Age of Steel)
 * After a heated discussion with the TARDIS, Clara is let in by her without a key, to follow the Doctor into a pocket dimension against his orders. This exact sequence of events was previously also done by Charlotte Pollard in AUDIO: Zagreus. Like Clara does in this story, Charlotte also called the TARDIS a "cow" in AUDIO: The Next Life.
 * The TARDIS interface was previously seen in TV: Let's Kill Hitler. Back then, it also showed companions.
 * Clara has previously mentioned the TARDIS not liking her. (TV: The Rings of Akhaten).

 * The device the Eleventh Doctor puts on Emma's head to connect her to the "subset of the Eye of Harmony" has a remarkably similar design to the one the Second Doctor uses to show his own thoughts to Zoe Heriot at the end of The Wheel in Space.
