When Baltar and the Number Six, who lives in his head, have a falling out, she abandons him, only to surface a short while later aboard the Galactica. But now she's called Shelley Godfrey, everyone can see her, and she's telling them that she has evidence, passed on by the late Dr. Amarak, that will prove Baltar sold out the human race to the Cylons.
With Baltar in a panic and trying to save himself, Number Six focuses her charms on Commander Adama. But the Commander is wary of this stunning stranger and has her followed while her evidence is analyzed.
Kara struggles to recover from her injuries while Chief Tyrol and the crew try to reverse-engineer the Cylon raider she piloted home.
Meanwhile, dual Sharons face their own challenges: on Caprica, she and Helo are on the run from Cylon centurions; on the Galactica, she's terrified of being exposed as a Cylon herself.
