I was rewatching Baltar's Escape the other day and something struck me. Does it seem to anyone else that there is a whole dynamic missing between Sheba and Baltar? She is Cain's daughter, after all. He is well aware of who Cain is. Why is she not included when Baltar addresses Boomer, lamenting that Starbuck and Apollo are missing from his group of hostages? Would he not see her as someone to settle some debts with as well? Or is he simply not aware that Cain had a daughter and he has her as a hostage?
Or, I am just overthinking things again.

But it seems to me there could have been a whole other story arch to that episode.
