In the latest episode of Season 2, “Lucky Day,” Who gives us two versions of this trope: one short term, and one with much bigger implications. Here’s what happened at the end of “Lucky Day,” and why it could mean we’re about to get a very specific kind of villainous comeback. Spoilers ahead for Doctor Who Season 2 Episode 4, “Lucky Day” ahead! At the very end of the episode, Conrad is locked up for terrorizing UNIT, spreading misinformation, and a variety of other obvious crimes. Not counting flashbacks with the Renegade Doctor during the events of the Flux, we haven’t seen any Time Lords actually alive — other than the Master — since the 12th Doctor episode “Hell Bent,” in 2015.
