I tried to start a thread on this but it disappeared...
Anyway, I am sooooo excited!
I'm pretty sure Nathan will somehow be revived. I hope so. I love Nathan even though he's a borderline villain!
As for Hiro, I think he wanted Adam to suffer, and to suffer HARD. Cutting off his head would've been too easy.
What I want to know is why in the commercials does Claire say to Peter, "I've always loved you Peter!" Ummm....isn't he her uncle???
It looks like some sort of alternate universe or something and I know she's dating him in real life, but still...
