Battlestar Galactica S4E4 Spoilers

Wow, was there a really big revelation tonight, or am I reading too much into things?

The crucial thing in this episode for me was Baltar getting the shit knocked out of him by that soldier, and the Six in his mind hauling him up and forcing him to take more of a beating. The first time she does so, we get a shot of Baltar alone and he looks conceivably as if he's doing it himself--pulling a Fight Club so to speak.

But that second time, we get a shot of a clearly dangling Baltar. His knees are bent, and when he moves, it's completely unnatural. The Six in his head appears to be an actual entity that can interact with the world.

The question of the Baltar-in-head and Six-in-head has been one of the central, fundamental mysteries of the show to me. We had the red herring that Baltar saw Six because he was a Cylon. We know now that he is not. Since then, the question of what these entities are, exactly, has been left open. I was working under the assumption that it was just a writer's device mostly, Baltar's subconcious or something like that.

The latest seems to confirm to me that they are real, and they are working towards a purpose. They appear to be agents of the one true God. Are they stand-ins for Angels? Is one an Angel and one a Devil? Remember in an earlier episode this season when Baltar saw himself, which previously, only the Six saw the invisible Baltar? What was that scene hinting at?

I remain convinced that there's a third party in this war, and has been from the start. We have the Cylons and the humans and.... something else. Aliens, or a more advanced human civilization is what I am guessing. Apparently, there was something like this in the old BSG. Ship of Light?

I believe this third party is responsible for the return of Starbuck as well. I don't believe Starbuck is a Cylon. Cylons wouldn't make the mistake of sending her back in a pristine ship. Whoever revived Starbuck did so wanting the fleet to know that things were not normal. Why?

I am starting to think about the recurring motif of "this has all happened before, and before." I have a developing theory that humans make cylons who eventually become humans and then make new cylons and there is this never-ending cycle of master/slave/freedom/rebellion that goes on. A struggle between Cylons and humans already happened on Earth, long ago. The humans fled, the Cylons pursued. Eventually the Cylons assimilated with the survivors and what we have is--the entire population of Kobol basically being human-cylon hybrids from an earlier creation. And then, the hybrids made new cylons, starting the cycle again.

Thoughts?
