Why would someone counter claim Pez on day 1? If Pez were faking a main character, wouldn't counter claiming be like saying "Hey Mafia, I'm a main character and probably a power role, go ahead and kill me tonight?" Just because no one counter claims doesn't mean a claim is solid imo
MDP makes a good point. Nobody should really cc on day one or within the first few days, as they've pretty much outed themselves to scum. It makes more sense just to wait it out and if you get killed off first anyway, the scum guy would obviously be caught right away.
I've got a few people who I think are scum, but doubtful they all are. Possible, but doubtful. UDK is one of them. CP as well. Shep seems to be playing odd. These are just gut reactions, honestly. I really doubt all 3 of them are scum.
