I think what the OP meant in regards to Noah wasn't who's blood was put in him but who did administered it. Meaning did Bob (The Company) bring Noah back or Mohinder. My bet is Mohinder. As another poster stated Noah didn't kill him when the opportunity came and we all know Mohinder is no killer. He would also be the one handling the blood so he can treat Nikki which would make it possible for him to get some into Noah as well. That's my guess at least.

In regards to Hiro its simply about principles and what is right. Going into the past is already dangerous as anything you do can change the future by a slip through the timeline. Hiro realized it was the desire of a son, a child, to want to take that chance and avoid fate.

Now my other thoughts are why did the group in the photo seemed so concerned over Adam? Yes, he basically can't be killed it seems and has lived four hundred years but what else? Compared to someone like Peter or Sylar that wouldn't concern me. These two can finds ways to get Adam's ability (Peter already has from Claire) and then every other one as well. My only guess is that Adam has lived all four hundred years in anger and caring for no one other than himself after Hiro's betrayal (in his eyes) and this virus Peter flashed into the future to witness was actually Adam's doing because it could potential exterminate the race (or most of it) but never him. Talk about having a chip on your shoulder.

Is anyone else just waiting for Peter to go off? As his mother stated he is the most powerful one of them all yet he still hasn't done much of anything to this point but seem lost and confused in both seasons. Oh and Lightening Ho's name is simply El. Or maybe even the letter L. But that's what they called her.
