Also note that Hiro said he stabbed sylar then he regenerated, but he didn’t have Claire’s power -_- People seem to think that Linderman would have regenerated Sylar as he wanted the explosion and nasty shit to happen ;o
I think having a scar would be fair play though considering he did explode and regenerate from atoms hehehe
The other catch is if Peter saved the cheerleader because future Hiro told him to because Sylar killed her, howcome she was alive in the future?
I think maybe because future Hiro came from 1 possible timeline and Present Hiro went to an alternate timeline (though similar) with the addition changes, but that wouldn’t explain everything.
