It's about grief. It's about family. It's about war. It's, "You don't have to walk the same path your ancestors did." It's "Your lived experience builds a world as deserving of your attention and care as your inner world" and "You inherited a flawed world, and you are flawed, and that is still beautiful" and "I made this beautiful thing and it's ending and that's just how it goes, but wasn't it beautiful?"
It makes me think about the worlds we make within ourselves and how they can be entrancing and wonderful even as they lead us to walk deeper into ourselves and away from those around us. It makes me think about connection, about how love can be so flawed sometimes but it is still something we need to hold onto. It asks "What if the monsters never asked to be monsters?" and "What if things can die before they're even born?"
It's about not being afraid of fire, not being afraid of endings, not being afraid of the world falling apart, of pain, of walking away, of reconciling, of finding new family and new love even as you mourn and miss what you lost.
It says, "Beautiful, wonderful things end, but afterwards, you can go home."
Caspian and co were like "gosh this duel idea is great and all, but how the heck are we gonna get Miraz, whos army is like three times bigger, to agree to it??"
And the Pevensies were all like: "No yeah we'll just send this little shit right here, he can provoke anyone into doing anything, trust us"
While Edmund so-you-bravely-refuse-to-fight-a-swordsman-half-your-age Pevensie just raised an eyebrow, grinning.
