Mafia 31. Twilight Dances.

Executing Slonysh is valuable information! Why? Firstly, if she is Mafia, everyone will be happy; secondly, if she is an Advisor, 100% peace will appear. So, there is no need to waste a day on NNV, because it's a pointless game.

100% peace, which they will try to quickly destroy. Considering the Knight's rationality, this is quite possible.

Executing Rimp is useless, because tomorrow he will be in the block.

No, that's not true. Even if Slonysh 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 Slonysh on a mission when there are so many suspicions about her. Moreover, if Slonysh is Mafia and will be hiding, then with a 50% probability she is a Dancer, which means we won't see any more stealthy kills.

This means that no one can be sure of Slonysh's peacefulness.

Personally, I cannot be sure of the peacefulness of any of the remaining players :3
