Heroes (spoiler)

OK, I finally got caught up with last week's episode.  I'm not sure that the black dude in the bar is the same guy that was bulletproof.  The black dude seems like some sort of "power neutralizer" and they're pretty clear about his identity when he's in a scene.

The bulletproof guy seemed like he had Magneto-like powers since he made the FBI agent's gun be pulled to the wall/gate, whatever it was.  Plus magnetic powers are good for deflecting bullets.

Well, that's my theory for this week, and will probably be completely overhauled next week.
