The season finale was very predictable but still good. I think Peter went nuclear and Nathan flew in, grabbed him and flew into space. Peter blew up in space not on earth Nathan went up and let momentum carry peter into space but still able for peter to fall back into earth. Sylar still lives and now knows he can be stopped because he lost his first battle and will teach peter how to control several abilities. He will help kill the bad guy in season two and try to take his powers and be killed by peter.
Seems to me that heroes can only use one ability at a time but can use the same ability multiple times like telekinesis on 2 or more objects. If they can use more than 1 ability at a time the nuke would have drained peters other abilities and he would have been unable to fly himself. I think the season finale should have introduced the Haitians way of blocking powers and peters mothers ability.
The only reason they didn't show the mothers ability was because peter would have been able to know what it was then use it since he absorbed it long ago and it might have been able to stop the bomb. Peter should find out what his fathers abilities were also so he can use them.
if they can use 2 powers at once it severely weakens the power and like suresh said if they use to many powers at once they could become unstable and die. Ted got shot in clairs house and went nuclear, peter got choked by sylar while absorbing more of his powers and absorbing nikkis and the anger put him in a overload and he went nuclear.
Nathan's wife has an ability in season 2 since Linderman healed her a side affect is transferring some of his ability or Linderman's ability mutating with her body type and creating an all new ability of its own. Nathan's two boys will have an ability also Molly walker and Micah will fall in love. Peter will contain to much power and by exploding will make him unable to obtain new powers.
if nathan dies peter uses nikkis multiple personality abilty to bring him back into his life cause peter is scared and isnt strong enough without his brother just like nikki was when she first got jessica and Nathan's personality will make him the villain in season 2. Molly said she couldnt find the villain because he would see her maybe she was talkin about nathan? since peter absorbed nikki's power he will have his brother nathan as the 2nd personality like nikki and jessica.
These are just some ideas that i think might happen or have happened.
