The 400th episode of 2MTL coincides with the swan song of one Clara Oswald (and Chip is blissfully unaware of spoilers or synopses for the next two episodes, so he's going to hold to that position for now). And as modern companion departures go, there's been no equal.

Check out Chip on The Incomparable Network's TeeVee podcast episode 118 for a longer conversation about "Face the Raven" with host Jason Snell.
