That's a very good point and another indicator that there was some noteworthy elements in this episode. However, just as was the case with last week's episode, there seems to be this overriding drive to get certain plot points lined up in order to set the groundwork for future storylines that will be featured in the remaining episodes. While I don't doubt that Moore and Eick had a planned out how they wanted the series to end, I'm beginning to have more and more issues with its execution. It's going to be hard to really get into the developments of future episodes if they're being built on the shaky foundations created in these last two episodes.

You mentioned that the ship is an allegory for how Adama is feeling inside. I would add too that it is an allegory of what is happening between Humans and Cylons. As was mentioned by Tigh, they tried humans by themselves, they tried Cylons by themselves and neither was strong enough to make it on their own. Only together will they be able to survive.

Now, here is the mighty Battlestar Galactica, a very human ship. She's been through a heck of a lot. Now, she's starting to fall apart. They tried fixing her the human way, but it wasn't going to be enough. The only solution was to coat the ship with the Cylon goo that would be able to fill the stress fractures and in the end, strengthen the ship into something that will last. As Adama pointed out, she wouldn't be the same on the inside. Something will have changed.

Change is the name of the game for these two groups. Here they are, having found that Earth wasn't all it was promised to be, faced at a crossroads of what to do next. Slowly, as each of them realize what has to happen. In the last episode, Adama finally accepted it when he told Tyrol to bring on the goo, he outright said it to Tigh this week. Anders mentioned it last week as well. Obviously, not everyone is on board with this and it will be interesting to see where this leads. In reality, it's starting to create 3 groups – humans who still hate the Cylons, Cylons who still hate their creators and humans, and those who accept that it's time to put aside those childish things and genuinely work for their survival.
