Kaede looks at the cards. And blinks at them. "Making a painting—picture, neat word, of my face, that's okay, but how does it know about my other usual face?"

The receptionist shrugs helplessly. "Wizards can do some very strange things."

Morty looks at the picture. "He looks nice!"

"Aww, thank you. You look nice, too."

Morty blushes. "Well, that's kind of you. Um, we can go a couple of places next - there's the classrooms if you want me to show you around the classrooms, or the dorms if you want to get a feel for the dorms, or if you're hungry we can go to the Crystal Hall, which is the cafeteria."

D'aww he's adorable. "Wherever you think would be most enriching to my tour experience, not being particularly hungry at the moment."

"Alright! If you're not hungry let's check out the classroom buildings."

They check out the classroom buildings! Morty gives her a general tour - "this is Dunn Hall, for science and programming classes that don't verge on Devisor or Gadgeteer territory," "Kirby Hall, magic and psi, I'm guessing you'll be spending some time here," "here's Laird, home of the martial arts classes, place where I have fallen on my ass more times than I can count."

"—oh right, I think I saw a magic flicker on you when I saw you trip one time."

"...huh?"

"I don't really know what it was, might've been an accident and it was tiny but I think it was there."

"Huh."

He considers.

"Nope, I have absolutely no idea what that might be about. Maybe it's a mutant thing."

She shrugs. "Yeah, no idea either."

Morty shrugs and shows her around a couple more class buildings.

"If you're hungry now I can show you the cafeteria, otherwise we can head to the campus store and get you all the stuff you might need for your dorm room and then stop by your dorm and drop it off?"

"Let's go to the store, why not. ...except I don't have any local currency, is that covered by the extradimensional kidnapping package I got?"

"It totally is! That's part of what the card's for - what the cards are for, actually, it tells the campus store that you have access to money from your extradimensional kidnapping package. If you didn't have one of those it'd just be to let you into the cafeteria."

"Alright, makes sense."

They go to the campus store!

It’s got a lot of stuff in it. There’s all the things a native of this world might expect from a campus store, but there’s also glassware, and bins of semiprecious stones, and throwing knives, and a small display of welding equipment, and there’s apparently a sale on liquid nitrogen.

Ooh. There is a bunch of stuff she has never seen and has no idea what it's for and she's enthralled.

Morty guides Kaede through the selection of various items, including bedding, toiletries, some local clothes, and a prepaid cell phone, explaining what some of these things are along the way. "If there's anything else you'd like, let me know. Or if you want anything else explained."

Okay wait cell phone what. No magic! And it's not even like attached to anything?????

“Oh! Yeah, I guess if you’re not used to technology cell phones would seem like, uh, total bullshit. They sort of - emit a signal that bounces off the atmosphere and gets received by other cell phones, is my understanding. They’re super handy? That’s maybe an understatement.”

"A signal. That isn't magic. What is it?"

"It's a special kind of light that we can't see. It turns out there's a bunch of different kinds of light, and we can only see this teeny little spectrum of it, but phones can make and receive a different kind that travels better, and we have a way of - like, you know how writing is a way of encoding speech in a way you can see? We can encode speech way better in that kind of light, and so we turn the sound into light and send it up to a satellite in the atmosphere, then the satellite bounces it down to the phone we're talking to, and light is super fast so it all happens just like talking to somebody who's right there. That was the worst explanation ever that I just did. It's complicated."

"It was actually really good! Though I'm not sure what you mean by light you can't see."

“So, you know how light can be different colors? We can only see, like, seven of them. Or four, depending on how you count it. But there’s a ton of different kinds of light, and some of them can kill you, and some of them can have messages encoded in them, and we can only actually see a teeny-tiny little fraction of them. Well, you and I can only see a teeny-tiny little fraction of them, there’s mutants who can see way more kinds of light.”

"So what's the difference between those kinds of lights and a colour?"
