A 100% peaceful player, who will quickly be eliminated. Considering the Knight's rationality, this is quite possible.
No. Even if Elephant is Mafia, Rimpel is no worse as a candidate. Firstly, -1 Mafia, as Ar noted, is always a good thing. Secondly, I don't think the Mafia are so stupid that they would send Elephant on a mission when there are so many suspicions about her. Moreover, if Elephant is Mafia and is just staying quiet, then there's a 50% chance she's a Dancer, which means we won't see any more stealthy kills.
Am, if you're peaceful, reconsider, Rimpel won't be eliminated anyway, your vote is wasted. A check is better than a wasted day.
