No idea actually.
He's a capable player but he doesn't have a strong history (yet) of being a mafia hunter. I don't even think he alluded to a role, either.
Most likely a banter kill.
I checked the thread after the game yesterday and that's when I saw the information about nightfall.
I literally didn't have time to vote because I hadn't even read the thread.
I don't think the majority even knew when nightfall was supposed to be. There was no mention in the OP, afaict.
I know the host posted that it was going to be after the game but it might have been too short notice.
