Lets try the optimistic theory. Lets say the vig ifred and hit scum. He would learn that player is scum, but not who his ally was. So we still have 2 separate parties firing blind. If they can find each other tonight, then we could be down to 1 scum by day 3.
If the vig is dead, and 2 scum killing per night we are 1 off from Mylo. SO lets hope that's not it.
