That was an awesome episode, except for one thing: Peter told Claire to run off by herself to get the police. He had no idea where Sylar was (he obviously wasn't dead), and no idea if it was safe anymore, and he still needed her regen powers, and they were both covered with blood, and--worst of all--he didn't have a good reason to stay behind. He just sat there doing nothing while the girl he was supposed to save ran off into the dark with a psycho supervillain still on the loose. The only possible explanation for this behavior is that the plot needed to separate Peter and Claire, and that kind of shoddy writing drives me up the wall.
That said, I repeat that this was an awesome episode. The scene in which Claire and Peter each realize that the other is a super was especially well done. I was disappointed that Sylar was obviously not Sean Bean (what's up with that, imdb?), but you barely ever see him so that's not a huge loss so far. Sylar is certainly confirming the telekinetic nature of his powers, but I can't decide if he has regeneration or not--he might have survived by slowing his fall, and then running away once he got his wind back, or he might actually have regenerated. Eden took him out easily enough, which makes me wonder why they've never just done that before. And I don't think the Haitian neutralized his powers, I think he just caught him when Eden put him to sleep.
