At the beginning of episode 2.02 "Valley of Darkness", Billy and Dualla say that they haven't seen each other in person since "two weeks ago." They were shown dancing together at the end of "Colonial Day". Only two days had passed on the show since then. See more »


Lt. Kara 'Starbuck' Thrace: [Starbuck has brought Helo to her old apartment on Caprica] You know, I never really liked this place anyway. The air conditioning doesn't work in the summer, the heater doesn't work in the winter, the rent's a crime. After the attack, I never... never pined over any of my old crap, never missed it - stupid view of that parking lot, broken toilet in the bathroom. You know, everyone I know is fighting to get back what they had. I'm fighting because I don't know how to do anything else.

haunting music
15 May 2010 | by (Switzerland) – See all my reviews

This review is less about the episode itself and more about the music of Battlestar Galatica in general. One of the highlights of the new BSG is Bear McCreary's soundtrack. This music is nothing less that brilliant, certainly the best from any television series. I chose to insert these comments under this episode because the music in this one is particularly haunting. It is so haunting, in fact that I nearly lost a girlfriend because of it. I had a date just after seeing this episode I was so distracted that my date thought I was being rude and aloof. I have been searching for a recording of it ever since the episode aired. For some reason the studio chose not to include it on the Soundtrack CD of Season 2. (Or did I miss something?) Anyway, the music fits to the action and emotion of the episode (which I will not spoil here) perfectly. It's almost as if the story was written to fit the music, not the other way around.
