Oh man was that good last night. I am so glad that this is back now.
I was not expecting Sylar to kill Peter but I knew that he was not dead, ala the tree branch in Claire's head earlier, but still. Also when Hiro met himself, oh man. I can't wait to see what the time line is all about and what is in it.
Not much of a suprize that Issac was killed off. We saw that coming from the first episode.
