Yeah, I thought this too, but then I realized that Adam would just show up again in the present, several thousand/million years more pissed off.
I got the impression that Mama Petrelli could have been the shooter…
And Revtim and The Controvert, you guys are just plain disgusting

I actually brought that up in last episode’s Heroes thread.
I speculated during the episode that showed her attack that she was faking it or was in on it. There was a little smirk she gave right after she talked to Parkman after her attack that made me think it was misdirection.
Of course, I could be reading more into it than the writers are…
And I tried to answer it a few posts later 
My explanation wasn’t phrased very well though.
The short answer is that Noah’s lens shape may be a result of genetics that result in less than perfect eyes, but from the perspective of his body they aren’t damaged, they’re following his genetics. So the blood restored his eyes to what his genetics would dictate they would be, rather than some objective ideal.
Similarly if someone were born only with 4 toes because of their genetics, and got the end of their foot chopped off, I wouldn’t expect it to grow back with 5.
I thought your explanation was fine; he wondered if it was brought up before so I obliged. I’m OK with that even if it’s an oversight. More so than I am with Peter’s disappearing Kensei symbol. 
Post from the Seattle PI TV critic’s blog where she compares “Powerless” with R. Kelly’s “Trapped in the Closet.”
Didn’t read the whole thing, but the part about Nightmare Man was one of my big peeves too. He was supposed to be really scary. I was scared at the end of season one. What he ended up being was a huge disappointment.
I think it would be a lot like “The 4400” then.
