Episode 4 - X-Men: Apocalypse
Dave and Cathy walk home from "X-Men: Apocalypse," which one of them LOVED and the other DIDN'T.
Cathy has seen all the X-Men movies, but can't remember any of them. Dave remembers X-Men: The Last Stand with nightmarish clarity.
SPOILERS in this one (and lots of planes going overhead, sorry).
