I want to know what mama Petrelli's power is as well. When she was standing in that doorway I thought she might be about to show us.

I was doing a lot of screaming at the set. At least Mohinder knocked him out. But then he stands there with his pretty eyes and doesn't follow up! I'm screaming, kill him! Empty a gun into him! Stab him 50 times! Bludgeon him with a blunt object! I don't care just make him dead!

I find it very interesting that the villian's power is healing. That's just a little extra warped. I have to wonder if Nathan is looking at his power and thinking about his wife.
