Yeah, that's kind of what I expected.

They exit the building, and Ananda sprouts some larger wings from her back. Do you want to fly to the main office? It's not that far, but, you know, flying is fun.

"...okay."

Ananda soars up into the air, then swoops towards a brownstone building attached to a large glass-and-metal geodesic dome.

Rebecca gets up in the air and follows her.

Ananda lands and leads her into the building.

”Hello, miss Luthra!” says the cheerful blonde woman at the reception desk, looking away from a screen showing a heated game of Solitaire. “How can I help you today?”

Uh. Rebecca, do you want to try to explain the situation or should I?

"I have no idea what's going on, how am I supposed to explain?"

That’s super fair, I just didn’t want to talk over you. Rebecca was teleported into my lit class by a creature she called a ‘cryptid’, from what is as far as we can tell an alternate universe where certain women, and no one else, have magic which includes shapeshifting. Her home universe seems to be at least a century in the past, as well.

The receptionist takes this in her stride. “Well, that’s certainly unusual. I'll send Mrs. Carson a message and she can see Rebecca in a few minutes. You can go back to class, Ananda."

"Do... I just... wait here?"

"Yes, dear, just take a seat and Mrs. Carson will call you into her office momentarily." She taps away at her keyboard with superhuman speed.

Ananda waves goodbye and exits stage left. There are several places to sit, a good number of which are even appropriate for people with wings.

Rebecca sits somewhere appropriate for someone with wings and starts singing quietly to herself.

The receptionist nods along.

After a couple of minutes, the door to an office with a nameplate reading ELIZABETH CARSON opens, and a statuesque woman in a pantsuit opens the door and sticks her head out. "Miss Arden? Please come in."

In goes Miss Arden, blinking at the pants. "Um, hello ma'am."

"Hello," Mrs. Carson says once the door has closed. "I'd like to offer my sympathies for the abruptness of your visit. And I'm afraid I don't have very good news: if you had simply been teleported, we would be able to easily return you to where you were from, but since you're from another dimension - I confirmed that magically, I'm not just going off linguistic cues and your confusion at the concept of mutants - it would be very complicated and expensive to get you home."

"Oh. Um. Well, are there boats that I can hire onto... here? That need magical girls?"

"I'm not sure why a boat would need a magical girl," Mrs. Carson says apologetically. "Is that the usual job for magical girls in your world?"

"Well, boats need us because of the sea monsters. Sometimes there are land monsters but I think usually you don't have a dedicated job of that."

"Ah. Our world does not have sea monsters, is I think the key difference here. Before we go further into what you could do to pay your return ticket, I'd like to make it clear that, as a young woman from another world who is stuck here and who is visibly not a baseline human, we at Whateley Academy are prepared to offer you lodging, board, and education for four years, as part of our 'fish out of water' scholarship."

"Oh. Uh, that's nice of you. Do you have music classes here?"

"We do! We also provide a more general education in literature, mathematics and science, along with classes to help you control and refine any powers that you possess."

"But if you don't have magical girls you probably don't know how to help me do that?"

"...if you have to refine your powers through some particularly arcane means, then we might not, but most powers in my experience respond to practice and experimentation? Is that not the case for yours?"

"No, they get better when I'm prettier."

Mrs. Carson raises her eyebrows. "That's a new one on me. We don't have specific classes based around beauty enhancement, but we do have a series of Costume Design classes and they do cover principles of fashion and aesthetics, so you might end up taking that instead of Powers Lab. What powers do you have?"

"Ice." She makes a little hailstone in her hand.
