Why is Heroes so awesome? Warning-Spoilers!

[FEJ]

Spoiler:

The Hiro paradox was the first thing I thought of when he ran into himself. And you could see in "String theory" he was trying to find the point in time to change. I do also like that he took the fall so "now Hiro" could go back and possibly save Ondo.
That being said I do not see the writers using that out. I really hope they don't. That wold be too easy and take a lot away from an amazing story.
It is my understanding that season 2 will have a lot of different characters-new heroes to say.
I am not sure if that is true, but thats what I have heard.
