Have you any idea where we are, Doctor?
Where is not as important as why, young man!
That little incident with the Daleks behind them, our time travelers hop back on the TARDIS and promptly get stuck “Inside the Spaceship” (Story Production Code C). You’d swear that the inside of the TARDIS really did conform to the dimensions of a police box, the way being cooped up in there begins to affect them:
This two episode story, also known as “The Edge of Destruction,” takes place entirely inside the TARDIS, the only story so confined and the only story solely featuring the Doctor and his companions. But while just William Hartnell (the Doctor), Carol Ann Ford (Susan), Jacqueline Hill (Barbara), and William Russell (Ian) are credited, one must make the case that the TARDIS becomes, for the first time, a character in Doctor Who as well. “Inside the Spaceship” is as much about the four travelers growing stronger as a team as it is about the mysterious workings of the TARDIS itself, even if the plot does hinge on a wonky spring.
