I found this from tv guide online concerning what Kara Thrace became after her death... TVGuide.com: What exactly is Kara at the end of the series? An angel? Moore: I think Kara remains an ambiguous figure. Kara lived a mortal life, died and was resurrected to get them to their final destiny. Clearly she was a key player in the events that led to [the fleet's] finding a home. And, I don't know if there's any more to it beyond that. I think you could call her an angel, you could call her a demon, the second coming or the first coming, I guess, chronologically speaking. You can say that she had a certain messiah-like quality, in the classic resurrection story. There's a lot of different ways you can look at it, but the more we talked about it, the more we realized there was more in the ambiguity and mystery of it than there was in trying to give it more definition in the end. TVGuide.com: So she is completely different than the hallucination/visions of Baltar and Six? Moore: Yes, Kara was physically among us. Everybody saw her. She was tactile, she flew a viper, she was around. She was with us. And yet, there was a body that died on the original Earth, and Baltar did the DNA analysis and it was her body, so she was literally brought back from the dead by something ? by some higher power or other power, and she came back to serve a function. Pretty interesting. We all thought she was a "head" Kara but it seems RDM cleared the air.
