"Thanks? Uh. What does that...entail."

"It would be easiest to handle it as a scholarship, which would involve you attending classes and staying in one of the dormitory cottages. We'll be looking for backers who can fund a scouting mission to your world, so we know if the forces we need to send to destroy these Sentinels look more like a high-powered superteam or a mercenary company or the United States army."

"Alright. Uh, we haven't had any formal schooling since this started, when we were six."

She nods. "We can work with that - we get students from places without a lot of formal schooling pretty regularly. So, for educational core requirements we'll have you in remedial tutoring, but for other classes, like art or magic or-" She breaks off. "Well. Usually we require that students go through basic martial arts training and Combat Finals, which are a nonlethal combat placement test at the end of each semester; will either of those be a problem, given your personal history?"

"No. Fighting humans is very different than fighting Sentinels."

"That makes sense. Then as I was saying, for other classes like art or magic or martial arts, you shouldn't be at any disadvantage. There's a bit of paperwork before we get you settled, which I can help you fill out. Shall we leave Louis's room and repair to my office?"

"Yeah, okay." 

Mrs. Carson removes a silver rod from her pocket. There's a shower of blue sparks, and they're suddenly standing in a nicely appointed office dominated by a mahogany desk. Mrs. Carson sits in an office chair behind the desk and gestures to a handful of seats opposite. She then removes a stapled packet of papers from the desk and starts going over them with a pen. "Don't need that... hmm, no... alright."

She slides the papers over to the twins. "Just fill those out, and feel free to ask me about any questions that confuse you."

The forms contain some relatively standard questions (home address [which has been crossed out], blood type, age, and gender [with a wide variety of options]), and less standard questions (tentative power ratings, GSD/BIT/MATD irregularities, age of manifestation, sexuality). It's not very long, but it is a bit dense.

"What do we put for gender if we're--genetically and socially and externally women but, uh, the phrase we used back home was 'discreet hermaphrodite'."

"If you feel most comfortable identifying as female, that's what you should put. If you feel that you would be better served by an environment containing students of varying gender identities, you can check 'other' as well, it's non-exclusive."

"I'm a girl. --And my dads were men. But it seems, uh, medically relevant, is there somewhere else to mention it if not here."

"Naturally you're female, I didn't mean to imply otherwise, just that it's a special enough situation that you might want the extra support. The information will be noted and included in medical records when you have your first check-up."

"I didn't think you were, I thought it was worth clarifying because if I had had weird in-between genderfeelings that doesn't mean I wouldn't socially present as a woman in most contexts. It's not something that's a huge deal in the context I'm used to, like, even aside from how nothing was a big deal that didn't have direct survival implications discreet hermaphroditism is a really common mutant trait in our world. We never got a huge statistical sample but, I dunno, somewhere between a sixth and half?"

"Hmm. We have a similar but not identical statistic, where about five percent of mutants in our world, mostly Exemplars, gradually change sex. Almost all such 'changelings', as some of them call themselves, find themselves comfortable with the change, even if they would not have identified as transgender before. We also have mutants who end up intersex or sexless, but not at nearly such a common rate."

"Do you get changes of people who don't realize they're fertile in one direction or the other, because we and a friend were accidents of the 'how is that even possible' variety."

"Fertility is practically guaranteed in cases of Exemplar sex change, but only in the conventional direction once the change is complete. We as in Whateley do not have problems of the 'I didn't know I was still fertile' variety - thank God - due to an anti-conception ward placed on the campus by one of my predecessors."

"Convenient. Anyway, our parents were both grown-ass adults who loved each other, the only thing wrong with our birth was, uh, what happened six years later but that didn't have anything to do with the accidentalness." Oh look forms. She fills out forms. She does not actually know her blood type, it didn't super come up, also there's no guarantee she won't have a weird mutant blood type or anything given how every other facet of mutant biology seems to have the potential for weird mutant versions. 

Neither of them has any idea what "GSD/BIT/MATD" mean. 

Age of manifestation: -5 months.

Tentative power ratings: They have no idea what the scale is, here. 

Sexuality: Bi-leaning-dudes

Sexuality: straight

Age: 16

Mrs. Carson looks over the forms. "Oh, sorry - the alphabet soup category, GSD-BIT-MATD is for any changes your mutation has made to your biology, such as fur or scales or in one particularly memorable case turning into a sentient cloud of nerve gas. Tentative power ratings, Louis is telling me PSI-6 for Edie and we'll get Emily in for power testing at the first opportunity, it's not terribly important anyway. As far as sexuality and gender goes, we'll need a verdict on whether you'd rather both be in the cottage for LGBT students or both be in one of the standard women's cottages. Ordinarily we'd separate you, but that seems like a bad idea here."

Immediate sister-arm-hug. "Very bad idea," she agrees.

"Yes, it does seem that way. So, where would you rather be placed?"

The two share a look that is above-average telepathic even for twins on account of literal telepathy. 

"...LGBT cottage. It'd be weird and uncomfortable if someone wasn't okay with our dads." 

"Very reasonable. Poe it is, then."

She types rapidly on a sleek black computer, and there's the sound of a printer printing from outside the room. "On the printer just outside will be your ID cards, which will let you into the cottage. System says there's an unoccupied room on the first floor, room 115. In the morning I'll call Professor Dresden, he's Poe's housefather, and let him know your situation, and he or one of his residents will give you the welcome tour."

"Okay, cool." 

Edie walks out to grab the IDs. 

There is shortly a yelp of "TWO THOUSAND AND TWELVE!?"
