Мафия. Learning to Live

Hmm. My gut tells me that you (or they) are up to something. I think executing Vis because of a strange fish scale is absurd. Think about it: we're already down two players, and if Vis isn't a member of the Mafia (which I suspect he isn't), then we're executing one of our own, bringing us down to three players – meaning we'll be almost doomed. The Mafia is probably laughing at us.
Is it worth doing?
