^Didn't Nathan swoop in and fly Peter over the sea, and then Hiro time travelled back to Japan for some reason.
By the end of its run I was watching Heroes purely out of habit. I was pleasantly surprised by the season 4 finale and I thought it was interesting that Claire outed them, but by then it was too late (not that I'm sure they'd have been able avoid the problems anyway).
Ugh, I'm just remembering that whole stupid plot about Sylar taking over Nathan's body but then it turned out Nathan's mind had somehow survived. Ugh and the whole "Sylar is a Petrelli...oh no wait he's not."
