The Doctor

Lore & Background

The Doctor is a Time Lord who travels through time and space in a dimensionally transcendental – 'bigger on the inside' – time machine: the TARDIS. This time machine, whose name is an acronym for Time And Relative Dimension(s) In Space, takes the exterior form of a 1963 police telephone call box and retains the appearance throughout the programme. Human companions accompany the Doctor through their adventures and serve as audience surrogate characters to ask questions which allow the Doctor to provide relevant exposition. 'Doctor' is a self-selected alias. The Doctor's true name is unpronounceable by humans according to spin-off media. In 'The Name of the Doctor', the Eleventh Doctor tells companion Clara Oswald that the name 'Doctor' is essentially a promise he made. The promise itself is revealed in 'The Day of the Doctor': 'Never cruel nor cowardly. Never give up. Never give in.'

In Their Own Story

The corridor is long and the fluorescent tubes above flicker at a frequency that makes the boy's teeth ache. He crouches behind a row of metal cabinets, his small hands gripping the cold steel, and watches the end of the hall. The Doctor is there, back turned, writing something on a clipboard. His pen moves in short, even strokes. The boy does not breathe. He does not need to. The Doctor never turns. He never has to. After a moment that stretches into a small eternity, the pen stops. The Doctor sets the clipboard down, straightens his coat, and walks away without looking back. The boy waits three more seconds. Then he steps out, silent as the tile beneath his feet, and follows the sound of the Doctor's shoes receding into the next corridor.
