Really neat theory. I have some questions though. I need to replay but from what I recall, Abnaxus claims April was split in two upon rebirth (not that she was already one half of a whole), maybe I'm mistaken though. I assume that your theory would say that Saga/Etta are the two halves of the whole spirit of the White, but I don't see any reason to think this would be the case. For one, why two pieces? Why not three? The notion of three is more important to the White(s) that we've encountered so far: the Mother that was, that is, and that may yet be. April was to be the Mother of one possible future, in keeping with the Spring theme - newness, rebirth, change.
Maybe when April died her Spring-Mother spirit split into two because there were two diverging future paths paved at that point - two Mothers for two possible futures, and whichever future plays out, that's the Mother that inherits the Kin legacy.
So maybe Saga and Etta are those two new halves, but I don't think the cycling works in that case. I'm not sure... something about this just doesn't fit for me... need to ponder more...
Edit: Also, if this is the case, what aspect of the White is the one that visits Saga as a baby, while Etta is in the House as well mind you.
