I'm posting this for two reasons, one, because it has probably one of the best jokes in the whole show (if you've watched it, I'm sure you'll know instantly)
He just shows up, kills everybody and leaves. He's a very unfunny character which is very appropriate for what the show was trying to be at that point.
maine was excellent at like… i don't know what to call the type of humor. where someone just raises an eyebrow like 'really? really?' and the other person digs themselves deeper
