Hayden Panettiere revealed that the first episode [of Season 2] picks up four months after the finale. "A lot of things happened [during those four months] that people don't know about," she teased. "A lot of things changed and people will be like, 'Whoa!'" Hayden also hinted that someone did not survive the season-ending bloodbath, but check this out: NBC is holding a Heroes press conference tomorrow on the show's set and all primary cast members will be present and accounted for. That includes Santiago Cabrera, Jack Coleman, Greg Grunberg, Ali Larter, Masi Oka, Hayden Panettiere, Adrian Pasdar, Zachary Quinto, Sendhil Ramamurthy, Leonard Roberts and Milo Ventimiglia.
