Bye bye Jammer, and almost Gaeta (saved by his leaked info at the "dogbowl"). This episode was painful to watch, not because it was bad, but because it was a day of reckoning for those who collaborated with the Cylons. None of these people liked the enemy, but they found themselves in difficult positions fending for their own lives, and trying to justify their actions by hoping they would have long term benefits. This episode was so well done, that you ache with the characters, and want vengeance and justice for them, but not necessarily in the way they seek it. Its gonna take some time for all the wounds to heal in this even ragger tagger fleet.
Battlestar Galactica is expert at muddying issues, and making the right course of action seem always elusive. All I know is that war sucks. Also in this episode was the introduction of life on a Cylon basestar.
Also, Veep Zarek becomes President sans Baltar and appoints Roslin his Veep. He resigns. She appoints Zarek her Veep, and begins a second term as an unelected President.
