Why's he scum? I dunno, maybe he's just a bad person inside. As to my reasoning for thinking that he's scum, firstly note his attempt to pull the bandwagon away from our stylishly departed vampire before everything fell down around their ears. And if that's not good enough, then yes, I did scan him last night, and he did come up mafia.
As to my certain townie's identity, I just looked back in the old thread and saw that Kanako already revealed it - I was referring to the first night's scan. Oh well, I still have an ace up my sleeve, it's just not what I had thought it was.
Anyway, regarding voting for other folks, normally I'd want to be a little more sneaky about it, put some pressure on different people, see how they react, to get more information for finding any other scum out there, but we don't really have a whole lot of room for subtlety at the moment. Let's just get rid of the scum we do know.
