I like the way the Narnians are so excited to have a living embodiment of magic in their country, and that this is why marrying her (well, aside from the needing an heir thing) would be of political benefit to Caspian. I also really like how she likes Caspian, wishes he'd had a better childhood, and doesn't like to think of him alone, but isn't sure that that's enough to base a marriage on... and so she takes the time to think, and to be sure, before she says yes. The quiet, careful, and vaguely melancholy feel to the story is lovely.
