The series flashes back to the events of the four months between the end of season 1 and the beginning of season 2, as Alejandra and Maya begin their journey to the U.S., Peter and Nathan's final fate is revealed, and the details of D.L.'s death are shown.
Peter returns from the future without Caitlin, ending up in the same place he left. Hearing a noise behind him, he fires a lightning bolt at the source and burns the hand of the person making the sound. However, the charred skin heals almost instantly. A man steps out: Adam Monroe. Adam wants to know why Peter attacked him but when Peter claims ignorance of him, he quickly figures out that Peter had his memories wiped by the Haitian on behalf of the Company. Adam tells Peter to try and focus on a picture of Nathan Petrelli, and his duplicated regenerative abilities should heal the parts of his brain containing his memories. Peter concentrates, then starts to remember…..Read the full recap

Mohinder: (opening narration) It is man’s ability to remember that sets us apart. We are the only species concerned with past. Our memories give us voice and bear witness to history, so that others might learn; so they might celebrate our triumphs and be warned of our failures.
Bob: (about Peter) He's not a toy, Elle.
Elle: He could be.
Adam: Well, you came to the right place. I have to warn you, though, it does get a bit old. Let me guess, you were living a perfectly ordinary life until one day you discovered you could do incredible things. Bet it was wonderful at first and thought perhaps you could save the world. And then you realized tragically that you were dangerous. And yet you talk to me after a decade, actually talk to me after three,
Elle: I accidentally set my grandmother's house on fire when I was six. Caused a blackout in four counties in Ohio when I was eight. I spent my ninth birthday in a glass room with an IV of lithium in my arm. I've lived in this building for sixteen years, ever since the shrinks diagnosed me a sociopath with paranoid delusions. But they’re just out to get me cause I threatened to kill them. I'm twenty-four years old and I've never gone on a date. Never been on a roller-coaster. Never been swimming. And now you know everything there is to know about me. I don't have the luxury of being more interesting than that.
Mohinder: (closing narration) There are many ways to define our fragile existence; many ways to give it meaning. But it is our memories that shape its purpose and give it context. The private assortment of images: fears, loves, regrets… for it’s the cruel irony of life that we are destined to hold the dark with the light, the good with the evil, success with disappointment… this is what separates us, what makes us human. And in the end, we must fight to hold on to.
Peter Petrelli: Peter is exposed to Elle, gaining the ability to project electricity.
Adam Monroe: Adam's blood can be used as a healing agent. His regenerative ability can heal the parts of the brain "damaged" by the Haitian's memory wipe. (Peter is shown to heal memories in the same way. It is not clear if Claire's and Peter's blood can act as a healing agent.)
