When the last Raptor leaves "Galactica" with Paula, Baltar decides not to go and stays on Galactica to finally do something noble. Baltar is issued a rifle and is assigned as part of "Galactica's" reserve force alongside Caprica Six. The "Head Baltar" only seen by Caprica Six and the Head Six seen only by Baltar then appear to them and they both realize they can both see both of them. During the assault on the Cylon colony ship, Baltar and Caprica Six defend "Galactica" from Cylon Centurions: Baltar performs well, taking down at least one Centurion, but in a bout of over-enthusiasm nearly shoots the returning rescue team before he is stopped by Caprica Six. The two later find Hera who is running away in a manner that fulfills the Opera House vision (with "Galactica" substituted for the Opera House). They carry her through the ship to the Opera House and enter it to find themselves in "Galactica's" CIC with the Final Five in similar positions as they were in the vision. Cavil takes Hera hostage, but Baltar tries to talk him down attempting to convince him to end the cycle of violence; in a rare moment of complete sincerity, Baltar confesses that his devout atheism has given way to the possibility of unexplainable, supernatural influence. Baltar's speech causes Cavil to falter and finally gives in when Colonel Tigh offers him resurrection in return for Hera and leaving humanity alone for good.
