Apollo shows off the new drinking establishment on Galactica, Joe's Bar, to Tyrol. Apollo thinks about Kara and wonders whether his marriage to Dee is worth saving.

Baltar's trial testimony threatens the very stability of the fleet. Lee assists Romo Lampkin in Baltar's defense. Some in the fleet begin to feel that Baltar is divine. Though he dismisses such beliefs, Number Six suggests that the followers may know more about his true nature than Baltar does himself.
