No, okay, let's say there's some truth in Kosha's words. Yes, she might have been obsessed with inflicting harm 24/7, but... I don't know, honestly. Considering that she apparently doesn't want to talk to me, I'll refrain from voting. If Kosha and Master are two crazy players, then that's a complete disaster.
I think we're wasting our time right now. Just arguments and shouting. Guys, even if Master is the Mafia, he's unlikely to be useful: he's taking too much risk. It's possible that the Mafia team is using him as bait because he's some kind of pawn. If Kosha is the Mafia, then there's not much point in executing her, because it won't give us much compared to executing other negative roles.
Therefore, I suggest we forget about everything and solve the clue. Seriously, if we eliminate the blonde, that's almost a guaranteed win.
Larisa has already solved the clue - according to it, Revan is Aysedor (who killed the Investigator without the right to resurrection).
But no one really wants to listen to me or her.
