As Heroes surprised us several times previously, I don’t have any doubt that it will again and again throughout the second season…

The writers are very skilled and will figure out many ways to create unthinkable events following the first season that will eventually lead to what we might have thought unlikely to happen.

I don’t know what’s wrong with referring back to quantum logic, especially in a series like Heroes that involves time/space travel. In fact I do support the theory of multiple universes and all, I didn’t deny that… But what I was trying to point at was a different thing. And in Hiro’s situation I am considering the fact that he travels through time and space in his own dimension. It is not mentioned in Heroes that Hiro can actually teleport to other universes and dimensions.

Anyway, back to the main point…
To support even further my point of view, I will use 5 direct quotes and examples from the series:

1- In episode 19 (.07%), during the Isaac / Sylar Confrontation, before his death and having somewhat reached enlightenment and figured out how the prediction of future events really works, Isaac says “You can’t fight the future”, and Sylar replies “Neither can you”.
This quote is quite self-explanatory.

2- In Episode 20 (Five Years Gone), Future Hiro tells Present Hiro that he (F.Hiro) stabbed Sylar but regenerated because he thought that he had Claire’s ability to regenerate. But that is wrong, Sylar never killed and took Clair’s power, not even in the F.Hiro’s Past. And the proof is the season finale! Sylar did actually survive the stab and did not have Claire’s ability, which led Hiro, in the first place, to think that Sylar regenerated because he had the Cheerleader’s power. And unfortunately creating the endless time loop of Hiro’s time traveling phenomenon, sending himself back every time to the subway with Peter to tell him “Save the Cheerleader, save the World”.

3- Twice in the Season Finale, we see Claire asking her dad (Noah Bennet) if he had a plan, after the bomb goes off: first time on the phone when she is taken by the Petrelli family, and second time at the end of the episode after the explosion of Peter in the sky.
Have you guys ever asked yourselves what could that fabulous plan be?
Here, let me help you…
As we have seen ever since the beginning of Heroes, Mr Bennet has always wanted to protect his family and especially his daughter Claire from “bad” people such as Sylar, and the “Company” itself. His first trial to accomplish this was by using the Haitian to erase the memories of Claire having a special ability in everyone involved in Claire’s life, including herself (but that’s where the Haitian refuses).
Anyway, back to Mr Bennet’s plan after the explosion:
In order to protect Claire from future threats and dangers, Noah will take Claire out of New York, back to texas, where she will work as a waitress in a restaurant, and also, her father will provide her with a new identity to conceal her true self. And by the way, she will be a brunette and her name will be “Sandra”…
Oh?!…
Didn’t I hear that story before? Oh yeah! in episode 20 (Five Years Gone)!!!
And also, didn’t we read somewhere in the Season 2 spoilers about the new characters arriving in the first episodes of the second season of Heroes? They talked about a new boyfriend for our beloved Cheerleader Clair… Yes! that is in fact Andy himself…Oh! and haven’t you heard? they’re getting married soon… But too bad Officer Parkman will find her and President Sylar will kill her :-(

4- Hummm… By the way, it seems that you guys forgot about the important lesson Hiro learnt back in Episodes 8 and 9, with Charlie the waitress who remembers everything. She dies! And no matter what Hiro would have tried, she still dies. Proof is that Hiro already existed in the past in her life, the picture of Hiro and Charlie at her birthday party proves that, and when Ando asks about it, Charlie’s colleague says that Hiro Nakamura was a great friend of Charlie’s back in the past, but unfortunately he was there for one month and then disappeared unexpectedly. That’s where Hiro realizes that the future cannot be changed and that he shouldn’t be playing around with time like that…

5- And Finally, as we have all noticed up until the season finale, all the events that led to the night of Nathan’s election happened exactly as predicted throughout Hiro’s journey, Isaac’s paintings and Peter’s dreams…
______________________________

The journey isn’t over, and we haven’t reached the day after Nathan’s election yet, where all the awaited and most important events occur…

The real journey starts after the disasters, where the heroes unite their forces to fix everything following the explosion of NYC and Sylar being president.
