I apologise if I have missed things out or misunderstood the situation, but is it guaranteed the messenger role is town? Forgive me, but some of this is new to me. Can we trust them?
Eric doesn't really appear to be defending himself, which would usually be a telltale sign someone's maf. But I'm not fully convinced.
Yeah, we could eliminate Alaris but since this new information has been brought out that he could help find mafia, I don't know if it's worth eliminating him. Although it's possible he might get killed anyway - I'm not sure if the Old Maid is immune.
So, here's my vote for now. If Eric decides to come back and stand up for himself, I'll change it.
[vote] Archeric.
