Wayne says:

So does Hiro meet up with his father in the past? I think his pops has eternal life or some crazy power.. I do agree that Nathan’s dad is the real villian and the mom knows more about the death of their dad… Slyar does not die??

Phone says:

It could be Nathan and Peter’s dad in disguise as their mom. Because, their mom seems to make the whole explosion seem like it’s a bet and she doesn’t want to lose the bet. Especially when Peter went back in time and heard the convo she had with Simone’s dad. She didn’t seem to want the explosion to be stopped at all even though Simone’s dad says that it could be.

Also, she seems to know a lot about Claire and where Claire really is. And she pops up whereever she wants. And she always has this evil look on her face and in her eyes.

I don’t know. just a theory.

Allen says:

Here is the revelations that I believe will come out in Generations.

Sylar is alive
Sylar’s (bio) father is Peter’s/Nathan’s father

john boy says:

I think its got to be some one thats been around for a long time dont forget there was a groupe of heros befor mind the old guy that peter was looking after. he had a chat with peter about his fate and all. so he must have some kind of power aswell so its has to be a villan from the past and a powerfll ona at that so the new season will be even better than the last and hopefully abit more action cheers NBC

kesel yang says:

i think it’s simone’s dad. When peter went into the past, he saw him even though the others didn’t. Maybe he’s still alive…
