Well, at first i thought that i will see a great fight between Peter and Sylar and poor sylar, it almost make me cry the way he died :X

More important, Nathan show that he`s a good guy, and his sacrifice make him the Heroe of the first season. Although i think Peter is pretty alive, now that he`s calm, he will have time to learn how to control that power...

And last but not least, the fantastic discover that the little girl gave to us, i mean, the one she have more fear off, the one that she can`t sees. Who in the hell will be?? God??

Or the new vilain of the 2nd season. Yeah, i`m pretty sure that is the new bad guy and after all, almost everyone survived and i think Nathan could has done the impossible, but who knows. After all, Hiro himself could return to the past and save Nathan buy teleporting Peter to a far far planet, them Peter explodes in that planet but he will survive off course and then, he will use hiro power to find a new planet and he will train his power and after that he will return to earth, to save the day one more time XD
