Setup 1: Optimally, a traitor death night one will give mafia a hard time. The death of doc or mason could quickly balance this back up though. Also, the mason will have a hard time trying to claim out loud with the hooker giving the doctor a wild spin. Setup 2: Now you never truly know what happens. Was the person you lynched just mafia? Or was he a miller? Lets hope the BG can shed some light on who's responsible for the deaths. Setup 1+2: BG, mason, vanilla mafia and traitor. The only four roles whereupon a night one death instantly tells what setup it is.
