Hiro tries to make his mother tamagoyaki to eat after being mistaken for a chef, but when he doesn't know how to make what she wants, he makes her waffles. During a conversation with her he convinces her of his identity and she agrees to try to use her power to restore his memories. She is successful and Hiro gets his memories back. Hiro convinces her to give him the catalyst as well and, after she does, she dies. Hiro and Claire reunite on the roof, but Arthur arrives and steals Hiro's power and the catalyst before throwing him off the building. Arthur sends Claire back to her time telling her to deliver a message to Angela that he won, then teleports back to Pinehearst where he adds the catalyst to a vat of formula. We then see that Hiro managed to catch a flagpole while falling, and has survived. In New York Matt, Ando, and Daphne try to get Isaac's sketchbook. After the bike messenger manager runs away, they get it and find the outline for a story revealing that Hiro will be lost in time. Ando, Daphne, and Matt decide to use the formula to make another time traveler to rescue Hiro. Ando plans to be that time traveler, but needs to figure out how to find the formula and gain the power. As Mohinder injects Scott to test the formula, Arthur senses a disturbance and goes to his office to find Peter waiting for him. He tries to disarm him, but his powers are blocked by The Haitian who's also there, but Arthur's too powerful for The Haitian to block for long and he urges Peter to shoot Arthur. Arthur tries to entice Peter into changing sides by promising to use the formula to restore his powers, but Peter refuses and fires when Arthur insults him. Arthur gains back his powers at that moment and slashes Peter's cheek, but misses the bullet and is only saved by the intervention of Sylar, who stops the bullet in mid-air. Sylar again asks if Arthur is his father. When Arthur says, "Yes," Sylar determines that he's lying. Sylar telekinetically drives the bullet along its original trajectory, striking Arthur through the head and killing him. The catalyst leaves Arthur's body while Peter stands over him, fading away. Sylar leaves Peter alone saying Peter no longer has anything he wants. Peter sends the Haitian after Sylar. In the lab, the test proves to be a success and Scott gets the power of super-strength.
