Well if you look at the percentages from last game, it was 7 people 2 mafia, so it could well be 14 people this time 4 mafia, sure based on powers i may have been balanced differently, though that doesn't necessarily mean there are two mafia people left, but it is a possibility. Based on the amount of deaths at night, could be two mafia with one having an extra x shot kill ability, or it could well be something else, like a 3rd party killer, or even just a really powerful godfather with a kill ability and bulletproofness.
