In TRADTiMM he was the ONLY TOWNIE that actually caught scum. He was also a role that for all intents and purposes wasn't actually IN the game but interacted with it (Tar game, etc), but when it came time for him to deal with stuff, he asploded and killed scum. (Suicide bomb was part of his role)
lolwat.
And that was the only town caused scum kill. I'm assuming he has the ability to reason out who's scum. He just isn't in the habit of telling us what he's thinking. I'd almost be willing to treat him like chamber, but I'd appreciate him giving information if he so deigns.
