I'm honestly pretty convinced with Bobby's - since the Witch of Truth was important enough to mention in the red statements, there must be more to that character mechanically. And a reverse Cynic doesn't seem that unlikely for this game.

But as I said, since we pretty much know that both Scruff and Bobby are mafia, we should probably get rid of them in that order as there's a chance we'll win tomorrow if he's telling the truth. I can really only see the trap option if there's a third witch - but we can still get them after lynching Scruff and Bobby.
