Mafia 60. Nonsense, mayhem, and a few artifacts.

First of all, I didn't insist on Del's execution. She has very little; the only post she wrote can be interpreted in different ways. Between her and Kosha, in my opinion, the latter exhibits more mafia-like behavior. Kosha wrote more and made some unpleasant slips. Sab said he suspects her role, but didn't say what role it was, and for me, it's not obvious at all. If I am pointed out to be wrong, then of course I will drop the accusations, but so far I don't see a single reason why Kosha could even be town.
Also, the position of both of them is curious, especially Kosha' same. She writes incredibly little, says things like "don't touch me," there's no analysis, nothing useful; she appeared late (college or not, she usually appears much earlier). It gives the impression that she was already mentally prepared for her own execution and it's not particularly important to her because of the baron's Dimension Door.
In general, Deli also seems like someone lying low, but she is inactive by nature, so I'm less certain here. Although the option that they are all mafia cannot be ruled out.
