I don't consider Sesam a mafia member, at least not yet. Things are more complicated with Shaman. He's a non-Necropolis troll and could very well have admitted that he killed Yashur just for fun. His tactic is actually quite clever and could lead him to victory. Although I've never practiced it myself, I've observed it many times.
I don't quite understand why Shaman changed his voice from Nebk to Rimp. And I haven't found any logical explanation for this from his side. It's not cool to do that.

And yes, I'm not mentally ready to lose randomly right now; I'm worried about that. Besides, night will be falling soon anyway.
