Based purely on intuition and behavior, Revan seems more like a Mirko, and less like a Mafia player. His gameplay doesn't really resemble that of a Mafia player. Moreover, Nebo found some evidence against him. As for the remaining Mafia players, it's more difficult. If it's Ea, there are no clues against him. It could also be Lizard, but it's hard to say anything about him due to his inactivity. Millicent and Wulfgar seem more like Mirko players, although I might be wrong.
