Poor Bulbasaur. :< But, I suppose that we must get down to brass tacks (tax?).

Bulbasaur said absolutely nothing apart from his sign-up, and no one talked to him as far as I know. Therefore, the Mafiosi must be clever enough to kill a quiet villager. This probably points to someone either A) with experience, B) with good judgement, or C) luck. I'm doubting C. As for experienced players, Latio and Desperado were the only ones who played in game one (apart from Bulbasaur, that I know of). Latio has said nothing I see as incriminating, but Quinn's knowledge of who hadn't called their moves was a bit... weird. He mentioned the Underling and the Overlord, which are Mafia roles, but he also mentioned an innocent - the Cleric. While this is a strange fact, the ability to know things like this is NOT in the Knight role description. I don't know how he figured it out. I do know that it's extremely incriminating that he knows the Mafiosi's movements before any Knight ought to. Therefore...
