I rarely participate, and suddenly I'm playing as a mafia member. How delightful. I can't really say anything about the Master. But I don't think he's a mafia member.
Mold, why don't you want to execute Arandor? Is it possible that Sesame randomly targeted Mold, and he turned out to be a mafia member? In that case, if Mold is negative, then Sesame is a town member.
So, I suggest this: we execute Arandor now, and tonight, let someone block Mold. The Sheriff can visit him for a check. And if he's already done that, then shoot him.
