Once a part of the fleet, Baltar is haunted by visions of Number Six, with whom he converses often (cf. Head Six). It is unclear to Baltar whether these projections are from a chip Number Six implanted in his brain while they were together on Caprica (the explanation originally given by the Number Six vision, which she later disclaimed) or if she is simply a manifestation of Baltar's own mind. Although the vision of Number Six manipulates Baltar through his fear of discovery, she lends him an edge by granting him knowledge of situations. The model of Number Six who had seduced him on 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.
