As Peter and Sylar fight, Mohinder is released from the ceiling. He manages to ram the map into Sylar, knocking him out and taking out the body of Peter but not before taking the List as well. He later takes the body to the Petrelli's mansion. Later on, Thompson arrives at Mohinder's apartment to convince him to work with Primatech, offering him vast resources to do research but Mohinder is more concerned with stopping Sylar. Thompson says they both have the same interests and asks him to join forces. At first, Mohinder declines the offer, insisting that anything that happens should be under his ground, because he had the List. Then Thompson tells him of Molly Walker and her sickness and power. Mohinder goes immediately to see her. Mohinder learns that she can stop Sylar by tracking him, but needs to cure her sickness of nerve deterioration. Mohinder discovers that his sister, Shanti, had the same illness and died of it, and that his father had found a cure for it without telling anyone. Mohinder researches and discovers that by giving Molly his own functioning antibodies, it will restore her humoral immune response.
