I've noticed that what would happen is that a scene started out with Kara's POV and then shift and ended with what seemed like Lee's - that's how it ends in Daybreak 2. I mean, look at their final scene, which starts out very clearly in Kara's head with her saying goodbye to Adama/Roslin and holding back tears - it stays with her all through what she's telling Lee (I got the sense that when he turned to talk, she was watching him) until the final moment when the camera shifts away from her for good and then he turns around and sees she's gone. But chances are we'd register it as Lee-POV since the ending is the last thing and all....I'm just guessing here.

As for the "you won't be forgotten" bit, I always thought that was a direct callback to their very first meeting and not actually what it might seem if we didn't have the flashback just before that. It's true, OBVIOUSLY he's never going to forget her, but with those two so much goes unsaid that I don't mind the obvious actually being stated once in a while.

And as for him owning her story and being the one to carry it forward in his memory, honestly I can't see a way past that with a dead protagonist. It's like the Buffy S6 opener, which wasn't about Buffy herself but about how the people she left behind were dealing with her death. Same goes for Bill and Laura, too.
