Recapping up to this point.
What happened last week: Not a hell of a lot. 
In general, plot checkpoints and random questions:
Roslin and Baltar are engaged, subtly and not so, in drawing their respective battle lines.
The Pop-Tart is still safely ensconced in the Boomerwomb.
Ginasix is no doubt going all Montgomery-Burns-y over her new thermonuclear toy.
And her peace movement is… what? Forgotten after two weeks ago, or about to become a serious player?
We still don’t know how Cylon strategy will be affected by the loss of the Resurrection Ship (though apparently episode 18 will provide important revelations on this point).
Who’s in charge of Pegasus?
Where’s Starbuck’s head at? After the dark eulogy she gave for Cain, she’s been a non-player in the last two episodes. Tonight, based on the preview, is all about her.
Other supporting characters we need to check in with: Helo (will he forgive the attempt to terminate the Pop Tart?), Tyrol, Cally, Billy (not counting his cameo at the end of “Black Market”).
Speaking of which, are the writers going to try to rescue the Dualla/Apollo thing, or just let it fade? I hope they either drop it or have something interesting in mind for it; I don’t want it to get pointlessly dragged out while they figure out what to do with it.
Mostly, I just want a nice, solid episode to erase the muddled mediocrity of last week. If Ron Moore is to be believed, tonight’s a corker.
