the Final Five create the other seven. Therefore, Ones knew the identities of the Final Five while the others knew only that they existed. For an unstated reason, Cavil rejected the human trait of mercy and turned against the Final Five. When the Final Five were resurrected, Cavil implants new memories for their life in the Twelve Colonies. He also alters the original programming of the seven other models so that searching for, talking about, and even thinking about the Final Five was strictly forbidden. Ones are played by Dean Stockwell. Number Two (Leoben Conoy) Leoben first appears as a smuggler at the munitions depot at Ragnar Anchorage, where he was exposed as a Cylon. Twos are religious zealots, carrying a pathological, and sometimes sexual, obsession with Starbuck. His Cylon identity was revealed ("Six of One"). Twos are skilled at deceit. Conoy manipulates Starbuck into thinking that a young girl he had kidnapped on New Caprica is her biological daughter. Twos display cunning minds and the ability to find and exploit others' weaknesses. Unlike other Cylons, Twos appear to be prescient and on several occasions prophesy future events. Twos are played by Callum Keith Rennie. Number Three (D'Anna Biers) D'Anna Biers was a reporter for the Fleet News Service. Roslin and Adama grant Biers access to all areas of Galactica to investigate her suspicions of a military cover-up surrounding civilian deaths aboard the Gideon. Their belief is that Biers will discover that military personnel deal with the same pressures and fears as the rest of the fleet, and that the events were a tragic mistake. The Biers model used the documentary as a means to relay information that Sharon was alive to Cylons on Caprica ("Final Cut"). D'Anna was revealed to be a Three in the episode "Downloaded". Threes are among the more aggressive models, and share a fatalistic understanding of the Cylon religion, believing that everything that happens is the will of God. Their religious devotion masks a deep questioning by Threes about why God allows bad things to happen (Theodicy). Threes possess aggressiveness, advancing themselves as de facto leaders in any situation. They are often rivals of Ones and Sixes. The rivalry with the Sixes partly stems from when Caprica-Six killed a Three to save Sam Anders from torture and death. D'Anna and Caprica-Six later reconcile and both of them are involved in a relationship with Baltar. Baltar
