Guillo flipped town but was an easily manipulated vote. Lappland has the Chuck parity cop mech on him.
So, if we do 'examine the wagon clearly' then Fuji & Pein stand out the most. Pein's claim is eh on the semantics of it all, as I don't see the purpose of confirming if a gift was received or not - players would either say they did (like Chuck did) or be found out about. Fuji claimed voyeur/follower, which I don't think he claims as wolf. Also his reactions to pushes and not being listened to see seem townie.
So, of the 3, I'd vote Pein first, if we want to go there. But no, I want to go magic.
