The next day, Linstrom tells Carol that Glenn's exposure to the plutonium blast caused his old cells to stop dying and his new cells to multiply at an accelerated rate, resulting in his abnormal growth. Linstrom admits that he and Coulter don't know if they can stop it and that if they don't, Glenn will keep growing until he dies. Awakening the day after, Glenn is initially frightened, then greatly disturbed. Carol sees him the following day to comfort him, but Glenn is now roughly 22 feet tall, distant, and depressed. While the public knows he survived the explosion, the military has kept the truth of his condition secret.
