Jack Harkness seemed to see him as one "cursed" with intelligence; Jack said he thought Oswald was smart enough to know who he was, and to want to end his life as a result. After being freed from prison by legal loopholes, Oswald was persuaded to become PhiCorp's spokesman for their medicines by Jilly Kitzinger for protection from people who still wished him dead. Eventually, he met with Torchwood and helped them in their plan to return humanity's mortality, as he had grown tired of his new life and wished to die. He killed himself and the Mother willingly, hoping for an enjoyable afterlife, even in Hell.
