Agree with all of that. It was a decent episode, and provided a good semi-reset for a lot of the characters and the issues they have going on.
As far as the Lee and Dee stuff, I'm still not sure what I make of it yet. In a way, I feel like their union was doomed from the start. Dee kinda betrayed Billy for her Lee infatuation, and I never believed that Lee was really that into Dee. I think from what we see in the show, it's pretty clear that he's meant to be with Starbuck.
That said, Lee could have tried to make it work, and he didn't. I'm not sure why, other than him really belonging with Starbuck. And considering her dishonest promiscuity, maybe Lee and Starbuck really do just deserve each other.
