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", 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 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", somewhat paralleling the episode itself, when the Doctor reveals that he brought Clara to Caliburn house in order to see Emma, not the ghost. He then returns to the pocket universe, where he reconciles with the monster. Since he went back to the exact same moment as when he was saved before, Clara arrives in the TARDIS as she did before, and everything that happened since he was saved was rewritten.

The TARDIS

 * 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."
