Good episode. I'm glad the way it ended, 'cos I'm not crawling trough the floor in my desperation to see the next season, but I'm still waiting for it. It's like you've eaten a full plate of food, and you don't feel hungry but not too full either.
It really made me feel worried when Hiro kept using his powers all the time. But saving all those other "heroes", reminded me of this one graphic novel, that told how Future Hiro and Future Peter saved "heroes" in the future (where else?

).
I agree with kpatrik and PhantomLord: it wouldn't have been too difficult to get Claire up in that room and to save Nathan. Well, let's just imagine that it was simply humanity that got on the way; everyone was too shocked to go find Claire. Although they weren't too shocked to realize, that by using Matt's power they couldn't erase all of Gabriel gray's memories and turn him into Nathan Petrelli... I think that's called brainwashing.

So "Redemption", huh? It was pretty hard to come up with a possible plot, unlike with "Fugitives", especially with the guite simple sneak peek at the end of the episode. Unlike with this one; apparently Tracy's a villain. What for? Who knows, maybe she traveled in extremly dirty waters.

But no, it seems that she just wants revenge. After all, we saw that at least one of the people she killed was a ex-guard in Building 26. And after being in the sewers for at least a little over six weeks, she has missed quite a lot.
Sylar becoming Nathan felt a little sick - like i said, brainwashing - but i liked the way they did it. When Nathan/Sylar was bothered by that clock so much.... Well, it really did gave me the creeps, but part of me still thought, "Cooool......"
The credit for the best sentences goes to...Sylar!
I'm too lazy to go and check what his actual words were, but when he started to say all those names of people who are going to die...

The way he said "mr. Muggles" was hilaroius, not to mention when he called Lyle Larry. I think he did it on purpose; after all, he's supposed to have the memory ability from Charlie. Never the less, funny anyways.
And then the other Sylar's sentence that i found funny:
Claire: "I'm going to make sure you'll die, even if it takes the rest of my life." (or whatever she said...)
Sylar: "Well, everyone needs a hobby."

And then just one wild guess: i think - as it seems that Matt didn't do such a good job with his brainwashing technique - that Claire could possibly be the thing to change Sylar back to...normal?
Besides, i truly think that it's only a matter of time before Sylar's himself again;
He knew that the clock was running early, so he hasn't lost his powers, and like Adam said in the second seson, the healing ability makes the mind to repair itself. Of course, this is little different than Peter's lost memory (Peter did well tonight, by the way), but as the real Sylar is still in there...
Can't wait to see Mama Petrelli's face when "her son" dies for good.
i can see it in my head:
Something big has happened, and Mama runs to Nathan's office. Nathan's there, watching out of his window.
Mama: Nathan. Oh my child, I'm so glad to see that you're okay."
Nathan: Oh yes, I'm just fine.
Then Nathan turns, uses telekinesis, and throws Mama Petrelli to a wall, holding her there, face to Nathan.
Nathan: And I'll just feel even better when I have your power.
Nathan changes into Sylar. He raises his finger and kills Mama Petrelli, taking her power. And above Mama's scream, we hear him whisper: "I'm back."
OKay, maybe that repeating himself thing was a little over the top, and I wouldn't really like Mama dying, but that scene just felt "heroes-stylish".
