In season 1, our heroes had to save the cheerleader to save the world. This time, the stakes are raised and it's now a deadly virus that's set to wipe out the globe. In an episode where you're not quite sure who to believe, Stephen Tobolowsky (Bob Bishop) talks us though the global threat that the virus plays and the Company's attempts to stop it. The task of changing history falls on the shoulders of Peter Petrelli, who gives his side of the story, as he befriends a new hero.
