Our first regeneration story! In this episode, we discuss the classic final episode of the Peter Capaldi era from 25 December 2017: 'The Caves of Androzani'. Which just leaves us one dilemma - which companion is in this anyway? All we can agree on is Don't Kill Bill. After that, it's the Cheeky Girls, evil Christmas trees and gags about blowholes all the way. Well that's Time Ram for you, innit. Also starring: Derek Jacobi, Chris Addison and Helen Mirren. Always Helen Mirren.
