1. I haven't rewatched lately, but I remember thinking that Roslin did give it away to Sam then. I don't think he knew Isis was special/different before then - but when she was all "this is the most important baby EVER". I think he figured out who it was. There's only one who would be that precious and important. But then she was lost in the Exodus, AND IT WAS HIS FAULT, and so he shut up about it. I always wanted to do a missing scene post-Rapture when it comes out to Helo and Athena that he knew she'd been alive on NC.

10. Gods, I hate that bit. At least they could've shown a glimpse of someone dying off to the side, some good reason for Sam to rush off instead of looking oblivious and cold.
