Heroes Questions...Spoilers for our out of towners.

Ponder with me, I've been wondering for awhile:
Why couldn't Peter fly on his own when he was about to detonate?
How does Sylar survive a clear stab straight through his abdomen?
How much has the future actually changed?
Did Peter travel, dream or receive a delayed message?
Will there still be a Petrelli in the White House?
Will Hiro ensure the Kensei stories outcome...or result in an important change?
Where did the Haitian end up?
Most importantly:
Will Aron return the ASECode that allowed for the hiding of Spoilers.

This is not a Heros thing, but Spoiler: The spoiler tag has been here since a few years ago.

Thinking about Sylar...

Although he hadn't clearly done so, it appears that Sylar could save himself with his freezing ability he gained from David or Walker. I doubt he gained sufficient control of Ted's abilities to seal his wounds that way.

There's already a Heroes thread and I started it. If you want to talk about Heroes, talk about it on that thread.

This thread is shorter because it doesn't have two posters bickering like husband and wife. Addressing the orginal question it's obvious you have to rewatch the series to understand much of the story, you may have missed parts. The point was the future was changes. The reason Peter couldn't fly by himself was he was fixed on holding back the chain reaction.
