"It's Sylar, actually," he corrects, his tone conversational and so saccharine sweet there's no way he's being genuinely genial. "You know. That psychopath who's spent the last year and some change killing people like you."

He takes a sweeping look around the room, his eyes dark and needy. He doesn't plan on killing any of them -- not yet, not until they piss him off or refuse him help -- but he wants them afraid. It'll help with his temper, as out of control as it still is at the moment, and he doesn't want them to think they can just push him around because he's the boss's "son".
