One final point: there's something really serious I'm concerned about. We know there are 4 mafia members, but what we don't know is if they're all working together.

It's possible that there's one mafia of 4, and one vigilante. Alternatively there are 2 mafias of 2, and one mafia attacked the other last night. At some point, there were at least two killing roles in this game. One of those killing roles has the ability to target the mafia and kill them.

Should there be 2 mafias of 2, the only person who presented that fact was Dee. She attempted to accuse me of pairing the mafia up into twos and suggesting I knew something about this, but this accusation is so bizarre as it came on Day 1. There was no confirmation of multiple killing roles at this point in the game.

I think it's likely that if there ARE two mafias, Dee is a part of one of them, and slipped up on Day 1 by making that accusation.
