S3, E4: Seeing a future where nearly everyone has abilities, a world destined for destruction, Peter resolves to prevent this earth-shattering end -- whatever the cost -- and so takes on a dark, unwieldy ability to save the world -- gambling (wrong) that it won’t destroy him and everything he loves first. After allowing Angela’s (Cristine Rose) half of "the formula" to be stolen, Hiro (Masi Oka) and Ando (James Kyson Lee) set out to uncover the identity of the Villain who hired Daphne (guest star Brea Grant) -- and must consult with the person who knows these rogues best...Adam Monroe (guest star David Anders). After the bloodbath at the bank, H.R.G. (Jack Coleman) resolves to get rid of his new partner. Meanwhile, determined to be a hero, Claire (Hayden Panettiere) hits the road after one of the Villains from H.R.G.’s old files. Suresh (Sendhil Ramamurthy) gives in to impulse. Linderman (guest star Malcolm McDowell) and Molly (guest star Adair Tishler) return in unexpected manners. A new romance ignites between two Heroes. Ali Larter, Adrian Pasdar, Greg Grunberg, Zachary Quinto and Dania Ramirez star. Randall Bentley, Ashley Crow, Jessalyn Gilsig, Ronald Guttman, Jamie Hector, Jimmy Jean-Louis, Ntare Mwine and Thomas Robinson guest star.
