More thoughts.
So, it just occurred to me (dunno why it took so long) that the reason Peter could handle Ted's power earlier but not at the end, was that he got it from Sylar too. So he had a double-dose of boom. No wonder he couldn't handle it in the end.
Also, I was watching the 1st one with my cousin yesterday... and I suddenly was struck by the parallel between Hiro seeing the modern eclipse in the 1st episode, and then the one way back in Kensei's time in the last one.
Things I really should have realized earlier.
