Making their way past a few blocks of skyscrapers, they come to a nondescript building reaching into the sky. Lina walks in, revealing a small library and charming cafe on the first floor, before quickly finding a larger than normal elevator that makes its way down lightning quick.

Oooooh, library and café? Nice!

Large elevators: a thing she didn't know she wanted more of. Why are they so cramped on Earth?

"We're up!" she says, stepping in and waiting for Bonnie to follow her into the elevator. There are 3 rows of buttons, reaching up almost 40 floors. It turns out Lina plans to take the elevator close to the top.

"I don't think I've ever been in such a tall building! Can't wait to see the view from up there!"

"Well, I mean, I've been to the top of the cupola in San Pietro but that's different, it's a church, people don't live in there."

"But you wouldn't know about it, as it's on Earth..."

"Do you have religion on this planet? Churches?"

This... is going to prove interesting no matter what the answer is.

"Not these days? I've never wrapped my head around how... people think about spirits and omnipotent world-makers being real things you have to keep in mind." The elevator is quick, too. Bonnie can't say much more until the elevator finally reaches its destinaion. It's a hallway, and looking both left and right Bonnie can see lots of doors, in bright and inviting colors like she saw on the subway map.

So no space Jesus? She's a bit disappointed but not surprised.

"Fair enough, it's controversial on my planet too. Oh, by the way, do you have a name for your planet?"

She hops out of the elevator.

"Oooooh, really like the colors! Will make it easy to get oriented, not that I need that but - you know - I like the idea."

"This planet's called homeworld! Something feels really honest about calling it that."

"And the colors are considered more to have decoration benefit than for navigation."

Near the end of the hallway, with doors on both sides, Lina opens a door to reveal a room. It's fairly narrow, but it manages to fit a wider than average bed and 2 desk, placed against opposite walls. The wall on the other side of the door looks like it's made of glass, but the view only shows another skyscraper that looks like it's covered in a black film material.

"So yes, this is the dorm."

"Ooooh, its spacey! Is there some kind of motorized blind? I think I'd like to take a nap, if there aren't urgent things to do..."

"It's a fixed polarization thing? Basically you can see through the window, but not another window. So you can see out, but not in to the apartment opposite yours. Make sense?"

"Oooooh, how does it work? Do you have any books that talks about it?"

"I... the filter works so light goes through 1 filter but is blocked by 2. I'm not good at science, but this place is built to let you learn so there are many books that talk about everything!"

"Nice!"

So, on the one hand, she is kinda exhausted by the whole... thing.

On the other hand! Science! Books! New technology!

It's a hard choice, but in the end a big yawn decides it for her.

"I really think I should take that nap, if that's fine with you."

"Of course! Sleeping when you want is important. It's good for your brainpower!"

So, on the one hand these are travel clothes and thus Dirty and she'd rather not sleep in them.

On the other hand she'd really love to nap Right About Now.

Yeah, no, she'll change out of them for the nap.

"I'd set up an alarm, but until I can find a way to charge my phone I should probably keep it off so it still has battery if for some reason I'd need it. Could you wake me up in... 40 minutes I guess?"

"I'll knock once that time has gone, OK?" She takes out her phone and taps a few buttons. "40 minutes starting now?" she asks.

"Yes, thank you!"

She says her farewells to Lina and, as soon as she's left, Bonnie locks the door, gets into her pajama as quickly as possible, and then flomps on the bed and quickly falls asleep.

There is a loud static, then a somewhat garbled voice says, very loudly:

"Wien. Nächster Halt: Wien."

Bluhrgh?

She jerks awake, and finds herself on the sleeper train, in her pajama, as it slowly rolls into Wien central station.

"Ausstieg in Fahrtrichtung rechts. Bitte beachten Sie den Spalt zwischen Zug und Bahnsteig. Sehr geehrte Fahrgäste, dieser Zug endet hier. Wir bitten Sie auszusteigen und verabschieden uns von Ihnen."

Was it all a dream? Well, no matter, she needs to get ready and get out of the train!

She changes into her day clothes, which are neatly folded haphazardly strewn on the seat next to her, then folds balls up her pajama, chucks it at the top of her bag and hurries out of the train.

This is - in fact - Wien!

She can tell, because it looks just like the pictures she saw online!

... the big blue sign with "Wien Hauptbahnhof" on it is also a decent clue.
