There are several chairs in the room. They are almost bizarrely nice!

"Just... you have a ticket, right? Let us take a look at it, help you find out more. See if it brings up any memories so you don't get disoriented like this."

She hands them the ticket, wordlessly.

It looks like this:

The man looks at it, absolutely stunned. He carefully feels it between his hands and speaks a quick phrase into his phone.

"We don't make tickets like that. We don't know how it was made, we don't think it was made using anything we have access to. This could only have come from... somewhere else."

How about she looks into the void for a while.

On the plus side, these chairs are really comfortable.

Water. Food. Shelter.

She grabs her water bottle, takes a couple sips.

"Do you mind if I eat a snack?"

"Well, I'm not sure what kind of snack that'd be?" says the person on the phone. Before repeating the words to the man who held Bonnie's ticket.

"A... Uh..." She grabs one croissant from her bag and shows it to them, still in its transparent plastic package.

The man instinctively gives a thumbs up, before explaining to whoever is on the other side of the phone that the mysterious person from a foreign civilization wants a... high area-to-volume pastry.

Ok, so. Water. Food. Shelter.

All good for now.

"I don't know how I got here. I don't know how to get home. I want to talk to my mum, if possible, but my phone doesn't work. She will be so angry, but it's better to call her now so she knows I'm safe. Am in the correct place to get help? Should I go to a police place? Will they speak English?"

"We don't know any of those two things, either, and we can't think of a way to let you talk to your... mother? This is a police station... and I don't know what English is. But I'll find someone to help you who knows this strange conlang we're talking in, just... wait in here a bit."

How can he not know what English is. They are speaking English! Unless it's some kind of language magic but this is real life, not a story. Magic doesn't exist in real life.

Good thing she's already at a police station. It should be the safest place to be.

"Thank you. I'm sorry. Can I look at a map?" 

It doesn't take long before a map of the entire planet shows up on the phone. The continents are much smaller, and none of them look like any continent on Earth!

That is... not a map of Earth.

Is she sure she's not sleeping? She tries to pinch herself.

Ouch.

Yeah, no, she's no sleeping. Probably.

"That map looks unfamiliar. It should not look unfamiliar. I..."

She's still not crying. Barely.

"I will just wait for the person you were talking about."

She turns off the phone. It's not connecting to any network, might as well save battery.

"Yes, yes, someone, I'll get someone who can manage to talk to you" the person on the other side of the phone mumbles awkwardly.

"Thank you."

She fidgets for a minute, then grabs her books and gets back to reading. If your brain is in a different universe, it stops worrying about the one your body is in.

Eventually, a woman shows up, waving at Bonnie and seeming friendly. "Everything here must be totally new to you!" She is wearing... a very unobtrusive mask made of a transparent material, from outside the building. And speaking in an unfamiliar accent, too.

It takes a while for Bonnie to notice the waving, but as soon as she turns the page her eyes inform her that Someone Is Trying To Get Her Attention.

She dog-ears the page and looks up.

"Hello! It really is! I expected an Adventure but... this is a bit much. I wanted to visit a different country, not a different world!"

"Welcome anyway! If it's adventure you want, there are few places better built to give it to you! But first, you want a place to come back to when you've adventured enough for the day, or so I would think?"

"Yes. Yes I would like that."

Water. Food. Shelter.

And then she can look into how to and what to and why.

"But I don't have any local money. You don't accept Euros, do you?"

"I don't, but the value of paper bills coming from another world would have to be astounding!"

She decides to enter the police station.

"You have a lot of money in your pockets, young woman."

"Ooooh. I can see that! Then you're probably also interested in my book! Although I wouldn't want to be parted with it, but I guess you could photocopy it but I don't know how copyright would work across worlds but also piracy is not theft and I don't know your laws so. I guess I could lend it to you, if you promise to treat it well. It was my dad's..."

"I do! I don't have a payment card yet and anyway I heard people in Germany sometimes don't take cards and this is not Germany, it's not even Austria but that was the logic. But also, it's not really a lot of money? It's enough to buy a train ticket in case of emergency, which is a lot of money but not a lot a lot?"

"If you trust me with it I could take incredibly good care of your book, but I'd feel best if I was given a virtual copy of it instead. I'd have to call the library and tell them I have an incredibly valuable book for them to scan, and have them set everything up instead."

"Well, it's not a lot of money because it can't weigh much more than a few pieces of paper, but then even a thick, dense stack of bills wouldn't be that much either."

"Makes sense. I guess when we get back in contact with my word we can arrange some payment or something? That would be fair, I think."

"Makes sense, yeah. I have... some coins and a couple banknotes." Plus her for-real-emergencies-only ones in the hidden pocket, but she's not going to talk about them.

"I have a question though... how do you speak this language?"

"I practiced it? It's a common pastime, on our end, to make and learn new languages, and I thought this one let a lot of things be said in a nice way, so I learned it."

What are the chances that they would create a new language and land on English of all things.

Oh well. It's not as if the day can be explained purely rationally, can it?

"What kind of accommodation would you get me? How much does it cost?"
