Hide (TV story)

Hide was the ninth regular episode of the seventh series of Doctor Who produced by BBC Wales. It was the first time Clara Oswald directly communicated with the Doctor's TARDIS and confirmed that it did not take a liking to her.

Synopsis
Clara and the Doctor arrive at Caliburn House, a haunted mansion sat alone on a desolate moor. Within its walls, a ghost-hunting professor and a gifted 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 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 of Defence, 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 takes a series of photographs of the 'ghost' throughout Earth's timeline. 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 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, who is trapped in a pocket universe 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, a reality 'well'. He goes to rescue Hila, who escapes, but is trapped in the pocket universe with the monster. Clara returns to the TARDIS, and after a brief argument with the voice interface, manages to break into the pocket universe and rescue the Doctor from the creature.

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 returns to the pocket universe to bring the creature home.

The Doctor

 * The Doctor says he loves carrier pigeons.
 * Emma tells Clara not to trust the Doctor, saying that he has ice in his heart.

Individuals

Popular culture from the real world

 * The Doctor and Clara introduce themselves as "Ghostbusters."

Buildings

 * Alec owns Caliburn House, which was built sometime before 1573.

Foods and beverages

 * The Doctor drinks milk.
 * Emma and Clara both have a glass of whisky which they don't like, and so drink tea instead. Furthermore, Clara calls whisky the "11th most disgusting drink ever invented."

The TARDIS

 * Clara calls the TARDIS "grumpy old cow."
 * The TARDIS uses her voice 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, 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. She's done this before (TV: The Doctor's Wife).
 * Clara says that they need a place to keep her umbrella, the Doctors states that he has or had a place at one place. The First, Second, Fourth, Fifth, Seventh Doctors all had umbrella racks in their control rooms, and the previous TARDIS control room operated by the Eleventh Doctor (prior to TV: The Snowmen) also had a coat rack.

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.

Production errors

 * The Doctor mispronounces the Metebelis in Metebelis III, saying it like its written, it's actually pronounced Met-a-be-lis. As made clear in Carnival of Monsters, The Green Death and Planet of the Spiders.
 * Several wires are seen running from the TARDIS to the equipment which opens the wormhole to the pocket universe, but when Clara returns, they are all missing.
 * When Clara flies the TARDIS into the Pocket Universe, the CGI design resembles that of the 10th Doctor exterior.
