When Commander Adama learns that Kara disobeyed orders and Jumped to Caprica on orders from President Roslin, he demands the president's resignation, with the implied threat of a military coup. Roslin refuses his demand and sparks a confrontation.
As civil war simmers in the fleet, the conflict on Caprica heats up. Kara completes her mission for Laura: She finds the Arrow of Apollo that, according to prophecy, will lead the fleet to Earth. No sooner does she pick it up, however, than she is thrust into a battle to the death with Number Six.
Meanwhile, Adama sends Sharon and Racetrack in a Raptor equipped with a Cylon transponder, to fire a nuclear warhead that will destroy the base ship. But when the missile release jams, Sharon lands the Raptor deep inside the base ship, to deliver the warhead manually.
Once outside her ship, however, Sharon is greeted by dozens of Sharon avatars, all Cylons like her, welcoming her home. She retreats, but is told that she and her fellow Cylons will meet again. She and Racetrack escape the base ship, which explodes.
Mission accomplished, Sharon returns home to the Galactica. She warmly accepts Commander Adama's thanks and praise for a job well done - then she coldly shoots him, point-blank, in the chest.
