World Enough and Time

TV Series 10 episode 11

Aired: 24 June 2017

This Twelfth Doctor story is mostly about the Doctor, Missy, and Bill, with fairly horrible things happening to most of them...mostly Bill. The Saxon Master only appears at the end, in what would have been an absolutely jaw-dropping reveal if the BBC hadn't spoiled it before airing. I'm not sure I've ever been as angry about a spoiler as that one.
