Plot
Knox escorts Adam through Pinehearst to Arthur Petrelli's room. Adam is terrified so Knox, with his increased strength, forces Adam's hand into Arthur's; Adam, screaming, rapidly begins to age and decay, turning into a pile of dust in seconds. Arthur sits up and removes the tube from his throat, having obtained Adam's cellular regenerative ability.

Daphne finds Matt Parkman, who knows her without having even met her. He explains that he had a prophetic vision of his future in Africa, where they are married and have a child named Daniella. Daphne gives him a card for Pinehearst and speeds off. Daphne penetrates Level 5 and meets with Sylar, who rejects her offer. Sylar releases Peter.

Claire and Sandra try to save Meredith from Doyle, one of the escaped villains, but the plan goes awry and they are all captured.

Ando and Hiro appear at Usutu's hut in Africa, where Usutu directs them to a painting showing Arthur and his assembled villains that they need to face: Arthur Petrelli, Sylar, Flint and Knox, along with the double helix.

Mohinder gives Tracy and Nathan injections, which he claims are DNA markers. Tracy collapses unconscious and a horrified Nathan lunges at Mohinder, falling into the next room and seeing cocooned figures before falling into a coma as well. Mohinder prepares to experiment on Nathan and Tracy, but they escape.

Peter and Sylar visit Angela, which convinces Peter to visit Pinehearst. Sylar believes he is too weak, and after a fight, Peter confines him to a cell. Knox, Arthur says that Peter is his son, and asks for a hug. Peter agrees, and Arthur steals Peter's powers.
