However, nine months later, a new group of incurables arrives, and Chip leaves the welcome party with the intention of using the newcomers' explosives to blow up the master computer. A physical struggle with Wei, who has the body of a young athlete, results in Wei being shot. Just before he is killed, Wei reveals his true motive in creating the dystopia: "there's "joy" in having it, in controlling, in being the only one." Chip knew all along that it was power hunger, not altruism, that drove Wei to chicanery and murder. On his way up from the underground city towards sunlight, Chip tells an angry programmer: "'There’s joy in having it': those were [Wei's] last words. Everything else was rationalization. And self-deception."
