This is the part where I lost it to the blubs:
Susan grows older and grows up. Sometimes she hears Lucy’s horrified voice in her head, “Nylons? Lipstick, Susan? Who wants to grow up?” and Susan thinks, “Well you never did, Luce.” Susan finishes her degree, stays in America (England looks too much like Narnia, too much like her siblings, and too little, all at once). She starts writing for the local paper under the pseudonym Frank Tumnus, because she wants to write about politics and social policy and be listened to, because the name would have made Edmund laugh.
She writes as Susan Pevensie, too, about nylons and lipstick, how to give a winning smiles and throw parties, because she knows there is a kind of power there and she respects it. She won wars with war sometimes, in Narnia, but sometimes she stopped them before they began.
Peter had always looked disapprovingly on the care with which Susan applied her makeup back home in England, called it vanity. And even then, Susan would smile at him, say “I use what weapons I have at hand,” and not explain any more than that. The boy ruled at her side for more than a decade. He should know better.
