Battlestar Galactica
Six Degrees of Separation
S1 E7:
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.
