For now, I'm inclined to believe Meggerson and Vespers; they seem to be doing a better job than the Master, whom I remember as a pretty good analyst. So, for now, I'm lynching the Master.
For some reason, I got the impression that the Mentor isn't afraid of being lynched, so the question is:
Scavenger: eats the player they killed. Gains immunity from lynching for one day and from death for one night. The eaten player cannot be resurrected or raised from the dead.
