So, TSY made a play there that was fucking epic. I want you to understand this.
His day 1 was entirely excusable. It's perfectly fine to come in and drop a vote and not do much else.
His day 2 play was the real risk and just fucking amazing play. He had ONE post with ONE vote. That one vote was for mafia - every single mafia player in chat was like, "OMG, TSY = COP." There's literally no other conclusion that you can pull out of that when you know DV7's alignment. In a game with 15+ players, that's just a risk you can't take.
Without literally the entire mafia jumping down TSY's throat in the round that he was lynched, TSY doesn't go there. TSY's lynch had to be manufactured by the mafia in order to avoid having to hit him at night.
What did that do?
It gave enormous information when DV7 turned up bad. Folks could go back to that round, look at the TSY vote, and read the reactions to it. They were DAMNING.
All at literally zero cost to the civs - TSY was vanilla. He forced enormous plays by the mafia players, to their detriment. If TSY had hit a civ with his lone vote? Well, then that gets to be used as street cred for the person he voted for - because if TSY isn't hit at night, then the mafia just thinks, "oh, well, TSY just shooting in the dark. He can't be cop, because he wouldn't tag an goodguy investigation like that."
imo, it was the best play of the game and TSY played civ MVP.
