seduces D'Anna by exploring her crisis of faith, which leads to her secretly committing suicide (a major Cylon taboo) to experience resurrection. She feels these near-death experiences will answer questions regarding her faith, notably the identity of the Final Five. D'Anna eventually sees the faces of the Final Five ("Rapture"). Unfortunately, as she does so, the other Cylons vote to box all Threes. Cavil tells her that what she had seen regarding the Final Five was unacceptable and that her memories would be kept in "cold storage". D'Anna, but not the other Threes, is later unboxed ("The Hub"). Threes are among the more anti-human Cylons. D'Anna tells Baltar that she believes that humanity must die to prevent future generations of humans from seeking revenge ("Exodus" Part II). She is temporarily the leader of the "rebel" faction of Cylons that makes peace with the human fleet, but when the first Earth is found to be a devastated ruin, she decides to stay there and die rather than continuing the cycle of death, exodus and rebirth. Threes are played by Lucy Lawless. Number Four (Simon O'Neill) O'Neill poses as a human physician who treats Starbuck for a gunshot wound in what was supposedly a resistance hospital on Caprica ("The Farm"). In reality this was a Cylon "farm" set up to breed human-Cylon hybrids using captured humans. Simon performed invasive tests on Starbuck's reproductive organs. He was revealed to be the 4th model in the episode "Six of One". Fours are consistently medical specialists. Another Four poses as a married man in the Colonial Fleet. Cavil at one point asks Simon to leave his life behind and destroy the ship he lives on. He defies this order to protect his wife and her child by committing suicide and flying out of an air lock. He was not close enough to a Resurrection Ship and therefore died permanently ("The Plan"). Fours are played by Rick Worthy. Number Five (Aaron Doral) Doral debuts as a public relations worker for the abortive Galactica museum (miniseries). Another Five sneaks aboard the Galactica and detonates an explosive ("Litmus"). This event prompts the fleet-wide announcement that Cylons can have a human appearance. He was revealed to be the 5th model in the episode "Downloaded." During the Occupation of New Caprica, the Fives are anti-human and aggressive. They specialize in public relations and control, using large-scale events and media manipulation.
