Who's Galactica's CAG?

I was musing about my weird girl-crush on Katee Sackhoff and then somehow it occurred to me that, after the last episode of this past season, it's very unclear who Galactica's CAG is. I can't remember if Starbuck or Lee was CAG immediately before Starbuck's "death". But then obviously Lee was CAG after she died. But that was only until Adama dismissed him from the military entirely. And I think maybe Helo was CAG on Galactica at one point in time, but then he became XO. And even though Tigh seems back to relative functionability (and Cylonism), Adama has to be a little wary and probably still has Helo as back up XO. So that rules him out. So that pretty much leaves Athena. And now that I've gotten to this point I realize that I do in fact know who the CAG is because we saw it in the last episodes. It's Racetrack*. I'm guessing it's her rather than Athena since Athena has that baby to raise. And she's a Cylon. So now the question is, will Lee be reinstated into the military, and if so, will he be CAG? Is Kara really alive? (Her recurring role on Bionic Woman is making me question this.) If she is, will she get back on Galactica, or is she just around to convey her messages to Lee via Vipercom?
I have conclusive thoughts on these things. Katee Sackhoff looks gorgeous in the Razor trailer.


*Reevaluation (i.e. rewatching certain episodes) has brought to light that I was incorrect. Helo is Galactica's CAG after Lee's dismissal. Guess he was doing that while on call as backup XO.
