The third one is intended to be the cast for a spoof if I ever spoof the show (which might not happen since I don't want to make someone who hates the show uncomfortable since she's not even comfortable with saying Luz's name.)
Also I don't really ship Lumity but I'm not sure I have a choice since I ship whoever I casted as Luz and Amity, how else can they end up together in the cast memes?
