I think Sedition sounds pretty genuine to me. Either Yudi is inactive, needs replacing and will hinder town progress anyway... or he was mafia and we get a successful lynch. I don't really see any reason not to trust Sedition at this point. He may be building up a lynch/modkill on a town member because he's mafia, and he's had a habit of soft-claiming when vanilla, but with Yudi being the only person showing anything resembling guilt and Sedition being clearly mafia if Yudi is town, I think lynch Yudi and hopefully doc protects Sedition tonight to allow another investigation.
Lynch: Yudi
