This episode simply had to happen. Although some people complain about the fact that the flashbacks took up too much of this episode, I cannot agree more on this. However, it had to happen. Somewhere along the line, an episode like this had to be made, to tie up some remaining loose ends, to give a little more background on some characters before it's all over. Now was the perfect time for a "flashback episode", but now it's time to get down to the point, to finish off this fabulous series once and for all.
Besides the flashbacks, there were some key moments in this episode. Such as the splitting of the fleet in the sense that some are going to stay, and some plan to go out and find Hera, along with the entire cylon colony. Adama's entire speech, and the entire scene itself leading up to the final discussion at the end, was very well played out.
Remember, guys: this is the first of three parts of an ENTIRE episode. It was never meant to be standalone, but in a sense it has become this way. I haven't lost hope in battlestar galactica, and the writers will deliver. One week to go, one more week until we know the truth.
