Here are those who voted for Master, just in case. I'm guessing there's a mafia member among them. If not more.
Actually, I wouldn't be surprised if you're wrong, Snegovik. The mafia doesn't necessarily have to vote for their own, in this case, anyone could easily say "I don't believe in your psychology" and that's it, no Masters get executed. The mafia usually votes for their own when it's clearer that a hanging will happen. Not always, it can vary, but still.
Just remembered about Master, and he's right here. What do you think about those who wanted to hang you?
