Wherein Stephen Moffat takes our favorite companion in a generation and ZuZu's Petals her. But first we talk about the beautiful Picts vs Romans story, "Eaters of Light." Bill finds the 9th Legion and the Doctor finds an alien menace. And then they travel with Nardole and Missy toward a distress signal (the Doctor's theme tune) which winds up with Bill making a sacrifice and/or the Doctor failing to save his friends. It's a cliffhanger and we need a serious therapy session about it.
