Mafia 80. Chronicles in Plasticine.

Regarding the second night kill from the killer, I can suggest the following: he was going to check the manual again, but checking comes after the kills. The killing of the Mafia members affected the killer, and he froze. That's why there wasn't a second night kill.

Is the Mafia protecting the Town member or protecting the Mafia member, thereby revealing him?

What's the point of the Bear watching Kosha when there's redirection?

Yeah, both options are a bit strange. But one of them must have happened because I don't see any other options at all. I think there was a protection (or maybe not protection, but a block?) of Kosha by the robot, most likely. And a redirection by the Bear. This option seems more likely to me.
