After the rebel Cylon baseship rejoins the human fleet, D'Anna sparks a standoff by seizing Roslin, Baltar, and their entourage as hostages. She announces that she will hold these hostages aboard the baseship until the four Cylons hidden in the human fleet return safely to their own people. Tory Foster defects immediately, but the other hidden Cylons keep quiet. Back in command aboard the Galactica, William Adama consults with Lee, who is still acting as President in Roslin's absence. According to prophecy, the hidden Cylons will reveal the route to Earth, and Roslin has secretly ordered Adama to destroy the baseship — even with her aboard — if that's the only way keep the Cylons from claiming Earth for themselves. The human leaders thus face two grim alternatives: if the hidden Cylons defect, the humans must destroy the baseship to prevent the Cylons from finding Earth, but if the hidden Cylons stay underground, the hostages will suffer. As if to prove this point, D'Anna executes a hostage and threatens to kill more unless the three remaining Cylons join her. In response, Lee orders Kara Thrace to plan a hostage rescue mission.
