Caprica later experiences similar visions after her consciousness was downloaded into a new body. Whereas Baltar experienced visions of her, she experienced visions of him. Both visions acted in similar ways: they were seemingly crueler than the person they were based on and often manipulated the affected party against his or her own species. Shortly after Baltar comes on board Galactica, Head Six reveals that a device which he had previously seen in possession of Six on Caprica has been surreptitiously installed in Galactica's Combat Information Center (CIC) (the command and control center of the battlestar). Head Six tells him it wasn't her job to put it in there. Baltar realizes there is a Cylon on board Galactica, but knows he cannot reveal that information, or indicate the device is not a part of the ship without implicating himself in the destruction of the Colonies. Baltar decides to implicate a person on board who goes by Aaron Doral because he is a civilian who has had access to the CIC during the last several weeks and, as an outsider, would be more likely to not be trusted by the Galactica crew. Having already been put in charge of testing the fleet for Cylons, Baltar informs the Executive Officer that he discreetly collected hair samples of crew members and has found Doral is a Cylon. Baltar, however, had no method at the time for testing for Cylons in the fleet. Baltar also explains he saw Doral doing something with a strange-looking device in the CIC he does not recognize. This forces him to develop an actual method for testing the fleet for Cylons, having already "demonstrated" an ability to do so. The process he eventually creates is reliable and is done through the testing of blood samples, but is time-consuming (it takes 11 hours to test one person). In the episode "Six Degrees of Separation", Baltar is accused of being a traitor to the human race when a flesh-and-blood Number Six (after Baltar and Head Six have a heated argument over whether or not God exists) produces photographic evidence showing that Baltar carried an explosive device into the Colonial Defense Mainframe on Caprica, allowing the Cylons to carry out their nuclear attack. When it is found the evidence is fake, President Roslin holds a press conference publicly exonerating Baltar. Head Six tells him his public position is now stronger than ever
