While watching this last one one I tried to figure what made this future? The only different thing seems to be Claire went into hiding via her dad & never met her biological one. It leads to me to wonder if Claire, not Hiro does in Sylar.



No I'm pretty sure she knew Nathan was her dad-he simply thought she had died due to Sylar. Really the only thing they have to due to keep that future from happening is stop peter from blowing up in downtown NY.
