in england i think edmund mostly tries to keep a low profile and peter out of trouble. he's flexible, practical, not flashy, and tries to not let himself be overworked. like, say we frame the pevensies as third culture kids. edmund has had to play many roles and be many things, and that helps him adjust. he doesn't worry about the same things kids his age worry about, partly because they're not really his age, and partly because he knows which bullshit to avoid. he may always call narnia home, but he also knows he needs to learn how to work england, because the narnia he knew is gone. and this is not necessarily a sad thing. i mean, it's sad when things are lost forever, sure, but edmund works with it and keeps his head. fifteen years of ruling as a prophesied monarch has taught him that nations will rise and fall. a city may be rolling in their own splendor one day and, come next year, it'll have been decimated by some unforeseen catastrophe.

edmund redefines 'home'. he redefines 'loss'. he knows that EVERYONE's childhood memories are riddled with nostalgic fabrication. unlike susan, he's not afraid to have a foot in both worlds. dividing his allegiance between multiple worlds will not make edmund less of what he is. these worlds are a part of him, after all.
