Having just arrived aboard the rebel Cylon baseship, Roslin and Baltar are shocked when the ship's hybrid abruptly begins making jump after jump away from the human fleet. The hybrid is panicking because she senses that Natalie has died. Eventually, however, her jumps regain focus. She begins searching for the resurrection hub so that the allied human-Cylon forces can complete their original mission: to rescue the boxed Three/D'Anna model and destroy the hub, which is defended by Cylon forces belonging to Cavil's faction.
During all of these jumps, Roslin experiences visions in which Elosha, her priest who perished on Kobol, shows her a hospital bed where she-- Roslin-- lies dying. William Adama keeps a loving, grief-stricken vigil by her bedside. Lee and Kara stand sorrowfully nearby. Observing this scene, Elosha urges Roslin to relax her self-inflicted Presidential isolation and allow herself to love-- both for her own sake and for her people's.
Between jumps, however, Roslin resolutely acts like her normal self. She and Baltar try and fail to converse with the enigmatic hybrid. Meanwhile, Helo and an Eight develop a bond as they work together to plan and prepare their uneasy crews for the coming battle. Helo is thus especially upset when Roslin gives him a secret order: he must transport D'Anna directly to Roslin, who will interrogate her with no Cylons present. Helo warns Roslin that the Cylons, who expect mutual cooperation, will see this as a betrayal of the alliance. Roslin coolly insists that Helo follow her orders.
The baseship reaches the hub and a chaotic fight begins against Cavil's Cylon forces. Helo and the Eight sneak aboard the hub, where they find D'Anna already awake. Cavil and Boomer have resurrected her, but she has killed Cavil, and Boomer has fled. Helo, the Eight and D'Anna escape from the hub in a Raptor. Then the human pilots unleash a barrage of nuclear missiles. The hub-- the Cylons' wellspring of immortality-- vanishes in a blaze of light.
Back aboard the baseship, an explosion during the fight has injured Baltar. Roslin gives him morpha and staunches his bleeding as best she can. Then, under the drug's influence, Baltar confesses what she has long suspected: that his actions helped enable the genocidal Cylon attack against the Twelve Colonies. After he complacently explains that his faith in God frees him from all guilt, Roslin strips away the dressing she has put on his wound. He guesses what she's doing and begs her to stop, but she steps away. Laura Roslin is about to let Gaius Baltar bleed to death before her eyes-- but it's not just his life on the line. It's her soul, too.
