At first I thought the close-ups of the sweaty face and voice coming from the Cylon raider were Baltar. I was thoroughly surprised when it turned out not to be him. After all, a fuzzy, distorted "Bulldog!" sounds almost exactly the same as "Baltar".
Good episode, overall. Though I can't help but think that the Galactica crew is a bit dense, all except Starbuck completely buying the "escaped from the Cylons" story, and even with Starbuck it was like "Well, we've got a Cylon agent aboard, but I'm going take it easy and have a talk with Tigh first".
Also, if the Admiralty (maybe) intentionally sent a fighter across the armistice line to provoke a war, why were they so unprepared when the Cylons came knocking? And yes, at this point I have to agree with Bob. and admit that the writers are milking the War on Terror for all its worth. Adama's story parallels too closely the claim that the Bush administration knew bin Laden was out there and planning a strike, but didn't warn anyone or take any action.
