Well, in most conventional demographic respects.
There are no only children here.
Alli and Bella have all their classes together, which is nice - that wasn't always possible in elementary and middle school; here it's a matter of course.
This year they're signed up for gym but they can skip until two weeks into term, at which point they'll have their basics and Bella will be just as competent as anyone else. More so, relative to the general population. She has no idea what bonus she'll get and she's excited anyway. She's going to be able to actually go to dances, and dance at them, if she wants. Not the homecoming dance because that's not for underclassmen, but there will be others.
"Uuuugh," says Alli, "math first thing in the morning."
"Wouldn't it be funny if you said that and you got a math boost of some kind for your bonus?"
"No, that would just be horrible. And sad. Be sad for me if that happens, Bella."
"All right. What do you want to get?"
"I don't even know, is there a point? I'll just get something and so will you and that'll be that."
"Suit yourself."
The bus pulls in and out they get, uniform skirts swishing around their knees, swan emblems matching on their sleeves so everyone can tell who is whose twin.
She soon learns that there is a homecoming dance. She wants to go, but not alone. (Well, she wouldn't be alone, not really, but without a date.) So, she asks a random person, "Hey, is there a girl that is cute, single, and likes girls for me to ask to homecoming?"
Adana, nearby, facepalms. If there is one thing Savannah got - it was not tact.
Then she zips off at super speed, and is next to Bella the next moment.
"Hi!" she says, brightly, completely unconcerned about how people react to her powers. There's a shooting star emblem, on her arm - her twin is nowhere to be found.
"I am! Maybe you can! Homecoming is coming up and I know absolutely no one. Want to come to it with me?" she asks of Bella. "You're pretty cute."
"How is the first thing you learn after transferring in that Bella's gay, how is that a thing?"
"It's on the twentieth!" agrees Savannah. "And, I asked someone nicely for anyone cute, gay, and single. Because it would suck to go to a dance without a date."
"I didn't even think that many people knew, I mean, there's 'out of the closet' and then there's 'on the roof' and Bella is not the second thing?"
"Calm down, Alli, I really don't care. Yeah, my basics will be in by then, I'd like to go."
She does not look like she's going to be offended if Bella says 'dance-only.'
"Dance-first but maybe the dance'll go really well," shrugs Bella. "Have you got a name?"
"Savannah! Hi. My bonus was super-speed, if you hadn't guessed."
"Hope you get something good! I met someone who could only turn things yellow, I felt so sorry for him. I mean, his twin's bonus turned yellow things sunlight-blinding, but still. Poor guy."
"I don't even care unless I get something so good that Bella never leaves me alone," snorts Alli. "She wants big stuff."
"I'll be plenty grateful just to have basics, but yeah, why stop there?"
"See, I was kind of noncommittal and uncaring about it 'til I turned sixteen and got my bonus, and then it was the best thing ever. You want to see someone who was excited about it, talk to my sister. She was up until four waiting for when mom had us and woke me up 'cause I was born first. She wanted to know if it worked."
"Nah, none at all. She also wanted hints towards what I had so she'd know what she'd get." Smirk. "Then she got it, and was cackling for the rest of summer."
Savannah cackles. "She makes portals. If you go through, you keep momentum and end up somewhere else. Two at a time, only, but she thinks it's the best thing."
"Convenient, too. I even help her out a ton, because she needs line of sight - but she can use mine, too. And I go to places really fast. We won the superpower lottery, we're extremely happy with them."
