I can’t speak for character progression, but as far as plot progression went, our original Menagerie campaign in Episode 19 had the Menagerie, all swapped into different bodies (loved that), going to a Christmas Party at the HHL League Tower. Which turned into calling us on the carpet to stop messing around with the newly Iceland-replacing Vyortovia. Followed by all the non-Menagerie heroes being knocked out by Vyortovian magic, a prelude to the Christmas Cat Attack, starring the Yule Lads.
