Another day, another reminder of the great 2016 Doctor Who drought: it’s the anniversary of one of the greatest moments of modern Doctor Who, a moment one over four and a half billion years in the making.
Can’t quite remember why he found himself in such a pickle? Peter Capaldi’s Doctor is teleported into an elaborate torture chamber, one in which the rooms reset after a certain period of time, with the only routes to freedom being a) smashing through the thick Azbantium wall, or b) revealing his secrets.
So the Doctor uses the rules against the prison. Realising that resetting the teleporter means another version of himself is stored in its memory, waiting to emerge, he starts playing a long, long game: running the maze over and over again just to punch that final wall once or twice, before dying and starting the process again.
