Hiro and future!Hiro are so different - I suppose the whole "I failed and Ando died" thing could do that - but it was so awesome to be reminded why I like Hiro so much. He's just a bundle of innocent joy.
And damn, when did Peter turn into Neo? I have a bit of a plot bunny (actually, many many bunnies) about this ep, wondering how he got that scar, and why it stayed.
And then there's Nikki/Jessica and why Jessica disappeared, and Nathan (and Sylar, of course), and - I'm going to have to watch that episode again. I can't wait for next week.
