Heroes Season Two... begins tonight

The mega smash hit Heroes begins it's second season tonight. It's going to do a weird twist in the way it can only do. in the "tradition" of episodes "Six Months Ago" and "5 Years Gone", this season starts off with "4 months later." Going 4 months ahead since "how to stop an exploding man" Then the upcoming episodes will detail what has happened during those 4 months.

But the Question I ask is, who is the "Generation Zero". If Hiro, Nathan, Peter, Niki/Jessica, etc. are the first generation, then who were the originals?
Charles Deveaux
Linderman
Angela Petrilli
Mr. Petrilli
Kaito Nakamura

Were there others that were in this group? Which of these had "lost their way?" Would you say that Angela Petrilli and Linderman were consipiring with each other? And Kaito Nakamura resisted their plan? Could Mr. Petrilli be split between Linderman's plans vs. not blowing up New York, which ultimately cost him his life?

Interesting stance I say. Let the 2nd season of heroes begin.
