Finchley, 1942, two girls- or perhaps two women who appear to be girls- are throwing snowballs at each other in a park.
With a snap of her fingers there is a hole in the air. With a faint orange outline, the correct street is visible on the other side. She steps through with a curtsey. "Cool huh?"
Susan also steps through.
Then, seeming calmly desperate and suddenly much more like an adult, she turns to Zoe, and asks:
"Zoe.
I'm thinking of a place in Germany. It would be very, very good if you could make a portal there. But it might also be dangerous."
The portal closes behind them.
"Pff, I laugh in the face of danger. But what's a Germany? Seems like serious business. Bleh."
"It is serious business. Germany is a country where the government is killing a lot of people. I'm hoping you can make portals to the places where people are kept prisoner before they're killed."
Meanwhile Lucy has gone inside to look for Jill and Eustace.
"Sounds like a poophead country, for sure. I dunno about fighting a country. Turns out worse tham before sometimes. Bleeeeh, serious business. I just wanna have snowball fights and play paddleball and stuff."
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.
"Nyeeeeh time stuff. Can't barely do time stuff. Hi, actual real kids!"
"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."
