Not as much action or revelation here but I believe it is the stage setting episode for the grand finale.
I had a hunch Ellen was going to be trouble for Tigh and Six and I hate that I was right. It seems she gets around Tigh and she reverts to a manipulative trouble maker. I would use a different word but clean is required!
The stage is set to learn what Boomer will do now that she is back on Galactica, and how will Tyrol react. If how he acted after Callie died is any indication he's still in love with her.
The groundwork is laid for more about Kara and Anders. Lifesigns spiking at the end may lead to some interesting stuff.
I think that Baltar's flock is going to be a key factor now that they are armed.
Some nice touches: the cylon memorial wall, Adama comforting Tigh after the loss of his son, and the constant monitoring of the repairs. I think that's a symbol for the new blending of human and cylon.
