I think my favorite part was Rosalyn's confrontation with Baltar in his cell. She's laid her cards on the table and spoke pretty plainly about how she felt things were going to go.
One shoe left to drop is The anger Zarek must feel at Lee for broadcasting him as an internal source of confidential information in the previous episode. Tom's probably going to be even more sidelined than ever now.
To me this felt like a clean-up episode. Dealing with the tragedies from the past several. Cally died, how does that play with Terrel who's already pretty unstable. Tigh understands he's a Cylon, was he actually there with the Six to confess what he was and seek some guidance? I think his vision of his wife interfered with that. As if Baltar isn't hated enough, he's a free man fomenting a religion the rest of the fleet considers a wacko movement. The relationship between William Adama and President Rosalyn.
All storylines well written, well performed, and necessary, but they all felt like "B" plot-lines to Kara's adventure and the deterioration of things on the Cylon home-front. I guess we'll have to wait till next week to pick up on that.
When Baltar was being held up by his head-six though, the area around his armpits and where they meet the chest were noticeably cinched in. It's looking like Six is either a physical manifestation, or Baltar's an excellent illusionist.
