Finchley, 1942, two girls- or perhaps two women who appear to be girls- are throwing snowballs at each other in a park.
She sighs and starts walking towards her house
"Germany is already fighting a lot of people, 'though. They're at war against this country, and a lot of others. I don't think they'd be able to do much about it if we did rescue people from them.
Would it help if I told you more about what's going on? It sounds as though you're new to this world."
"It'd help if you didn't act like my mom. I could literally go anywhere and find people killing people. Well, almost anywhere."
"My world was really cool! There were witches and wizards and summoners and void things and werewolves and sand magic people and angels and animals that could talk and vampires and people who were rocks and pirates and these cute fluffy people with a spaceship and hextech and spirits and ghosts and meditation magic and a whole bunch of cool heroes all over the place! Too bad it was so magic, that the whole place exploded when there was a big war. I... I ran away. I kinda miss it."
"No thanks."
"There's lots of cool worlds out there. But that one was special, you know?"
"I think I do. I've only known two worlds, but I've spend half my life in each of them and I miss the Narnia I knew, and all the people I knew there, now that its a thousand years past and I can't go back. I'm trying to move on, but it's difficult."
She pauses in thought. And then Lucy and two children come outdoors.
"Hi! I heard you all had a big adventure. It sounds scary but neat, as all good adventures are."
"Well, Eustace used to be unpleasant to me at school, but then- well, I suppose you should tell that part, Eustace?"
Eustace says, ashamedly.
"I fell into Narnia with Lucy and Edmund, and because I was beastly I turned into a dragon. And a magic lion helped me stop being a dragon and since then I've been trying not to be beastly but I don't always manage."
"A dragon! I know lots of kinds of dragons. It sounds like you turned into one of the mean kinds. Do people turn into things a lot in Narnia?"
"There was also an evil witch who turned into a snake. That's the only person I saw turn into something. People talked about a prince turned into a donkey and another evil witch who turned people into statues."
"I've met some water dragons. They live in the ocean and can spit water so hard it can blow away hills. Those guys were tough! And cool!"
"Salty. Blech. I can make it rain! It easiest if I steal rain from somewhere else, though."
"Well, there's a story where dragons used to live in an ocean in the Far East and carry the rain to the land in their mouths because the gods weren't doing it like they should have been."
She takes one step that brings her halfway across the room with a brief flare of orange and blue. "Portals!"
