Last episode, Number Six did a pretty good Bruce Banner impersonation, warning Baltar that he wouldn’t like her when she’s angry. In Six Degrees, she makes good on that threat: After Baltar makes fun of the Cylon god a few too many times, the Six in his head disappears, only to be replaced by a real-life Six, who claims to have evidence of Baltar’s treason.
We can pause, for a moment, to recognize one of the funniest scenes in the entire series: Baltar arrives in Galactica’s command centre to find his fantasy woman standing among the crew. Except she’s not imaginary at all, and Baltar’s discovery of this fact plays out like a Marx Brothers routine. There aren’t a lot of funny scenes in Battlestar Galactica, but I suspect most of them involve James Callis.
