Storyline

Dr. Cottle works desperately to save Natalie 6 and Athena is sitting in the brig. With the Basestar having jumped into hyperspace with President Roslin and Gaius Baltar on board, Tom Zarek assumes the interim Presidency. The fleet has lost more than the President however as they had already transferred an air wing to the Cylon ship pending the attack on the resurrection hub. When one of the Raptors returns, they find a crewman on board, dead. Admiral Adama simply won't support a Zarek-led government and Lee Adama tries to arrange a compromise. He gets Romo Lampkin to help him find the right candidate to replace Zarek as interim President. Adama learns that Col. Tigh has been having sex with Caprica 6 and that she is pregnant. Realizing that he will go to any lengths to find Roslin and that he has lost his objectivity, Admiral Adama comes to a major decision about his future. Written by garykmcd

Quotes

Admiral William Adama: Mr. Lampkin, what are you doing here?
Romo Lampkin: Writs of forfeiture for the ships you're borrowing. The captains want to be absolved of any blame should anything untoward happen.
[Adama takes the legal papers and examines them]
Romo Lampkin: One of the less ennobling consequences of a legal culture. No one wants responsibility. Lee said you once gave him something before a mission. A lighter, was it?
[Adama begins signing them]
Admiral William Adama: Belonged to my father. Foolish to think a hunk of metal could keep him safe.
Romo Lampkin: And yet, that's ...

re: What a difference a week makes?!!

I have to disagree! While I would never say it was 'the best' of episodes, I must say that It was terrific to watch the casts best actors really ply their trade. The intensity of the drama was fascinating. Tigh is such an interesting character and Michael Hogan plays him so well. I hope when the series ends we will see more of him in some interesting roles.

I would like to see some more action, however, as I have been missing the fantastic fleet battles of earlier seasons. I'm expecting the season will be low on action, unfortunately, but leading up to an epic final episode (or two).
