No screenshots because the lobby expired, but check my two recent reports and the reports from others in that game. Pretty obvious that they deserve some kind of punishment.
It was basically, Castiel was part of a 3-man mafia and there was one arso at the end of the game. Castiel confirms us that he premade with Johny and proceeds to not be the final vote to lynch Johny, leaving Johny free will to douse me and the other mafia player (not Castiel, mind you) and then ignite. Giving Arsonist the win.
