So it comes down to the final four...one of us has to be mafia.

Psychoanut is likely not mafia. He claimed Cornerian. Earlier, teams star fox and star wolf seemed to have cleared him, for the most part. I don't remember if he was scanned. But I do know that he nailed a mafia who otherwise wouldn't have been lynched at that time. Heck, he might even still be alive if not for Psycho. I don't see any reason why a mafia would do that to his teammate, when it appears that all the mafia are indeed on one team.

I'm inclined to believe Autolycus' role claim of General Pepper. We've never seen an NPC in this game, and there's no reason to think that ATPG wouldn't include Pepper as a role. The role looks legit. Yeah, there's a typo, and ATPG is pretty good with catching those. But even the best make typos sometimes. That's pretty much the best case anyone (including myself) has been able to find regarding why Auto's role claim might be fake. And if one typo is the only reason we have why it might be fake, then it's probably legit.

That leaves Nightbringer. At one point it became obvious that you were Venomian. It made sense for Andross to only attempt to recruit known Venomians, or risk wasting a night on an un-recruitable character. You were likely recruited by Andross. Vote: Nightbringer.
