What I don't understand is in the future how did Nikki survive when DL and Micah didn't, and how did Syler get DL's power? Because just before Future Hiro is killed Syler opens the door by putting his hand through it.
Also how did Future Bennet, Parkman and Suresh survive because they were all in the plaza with Peter and surely if he blew up there in the future the only people able to survive would have been Claire and Peter.
