December was posting online to a trans support group as its volunteer moderator, so to say that she's surprised at being dumped on her ass in a v-necked T-shirt and slacks in the middle of a city is an understatement to say the least. She hasn't even got shoes on. 

What? What just happened? Central City isn't a real place name, right? And who's cackling? Isn't she supposed to have a monopoly on that? 

She lurches to her feet and tries her best to orient herself, her gaze whipping around to try and find the source of the laughter. 

Down the street, a man in an unseasonable parka is pointing a vaguely ray-gun looking device at a young man in brightly colored spandex. The boy's feet appear to be frozen to the ground, and an armored van has been overturned in the background.

There's a hesitant knocking at her mind, a gentle mental connection.

Does she want to be able to suppress other people's ability to cackle?

The question comes with the impression that the choice is entirely up to her, and she's free to refuse. If she pushes the source of the question away, it will leave her alone.

Yeah uhhhh maybe give her something to disarm the dude pointing a weapon at a stranger in public? That seems like a smart move!

It can give her intuitive skill with safely disarming people holding ranged weapons. Or maybe the ability to fire beams that knock things out of people's hands?

Does she want one of those?

YES FIRING BEAMS TO KNOCK THINGS OUT OF PEOPLE'S HANDS PLEASE

A spark of light blooms into some new internal space inside her, and suddenly firing beams that knock things out of people's hands is just something she can do, like moving her arm.

Luckily, the man in the parka seems to be fully distracted by monologuing.

"... and that's when I'll strike! So, you see, he has no chance against me! In fact ..."

She fires a beam to de-gun parka man. Figure out the rest later.

The gun bucks in his hand, and he lurches forward, grabbing to try to maintain hold of it —

— and, unfortunately, letting go of the deadman switch in his other hand, causing a device by his feet to emit a pale blue wash of color—

— while a larger man in a red and gold suit throws a rock at the ice around the boy's feet, and then somehow pulls him away in a blur —

— and leaves parka man frozen motionless in his own blue bubble, the gun suspended in mid-air just past his fumbling fingers.

Fascinating. Uh. She probably should not have done that so fast, that was awkward.

"Everyone okay?" She calls out.

She has no idea what she's doing but she will hopefully be okay.

"I, uh, think I twisted my ankle when The Flash pulled me out," the kid in the yellow body-stocking replies.

The man in red — The Flash, presumably — helps him to a seat on the curb.

"Thank you for giving me an opening, by the way," he adds. "I'll be back in a moment — I have to run."

He vanishes in a blur, speeding out into the city. He returns a few seconds later and starts blurring around the armored car.

"Hey, I'm Kid Flash — I don't think I recognize you?"

Something for healing sprains, please?

"I'm December Morning-Glory and I have no idea what's going on but the guy pointing a gun seemed like it needed to get fixed. Sorry, I should've had more of a handle on the situation before I did something. Uh, can I see your leg? I might be able to do something about it, not sure."

It can do a power for slowly healing sprains of consenting people at touch range, sure!

A second spark blooms to life within her. The two sparks don't seem to like each other much, and settle into a wide orbit around one another.

"Uh, sure?"

Kid Flash extends his leg with a wince.

She gently lays a hand on it and starts using the power. 

"Hopefully this works!" 

December looks up with a hesitant smile. 

She has no clue if Kid Flash knows if she's trans or not but she doesn't really care, that's his problem. He may or may not have noticed she's not wearing shoes. He also may or may not have noticed that she's 6'1. He probably is noticing that she is not wearing a bra beneath her t-shirt. (She still hasn't gotten the coursge together to go to a women's wear store to get something properly fitted, and besides, her breasts have been growing in this whole time so it'd have been a bit of a waste of her limited cash.) She looks about nineteen and is doing her best to look friendly and helpful without literally throwing a power at it.

Is she even still on Earth? Superpowers weren't a thing where she came from. 

"I'm really confused right now for a lot of reasons, I was in my apartment and then there was this — stretching sensation — and suddenly I was here and had powers?"

Kid Flash has definitely noticed that the older girl leaning over him to treat his leg is wearing a v-neck and no bra, but he's trying to be discrete about it.

"Uh ... That does sound pretty confusing," he agrees.

But it's not the weirdest thing he's run into since he started helping The Flash.

"If this is your first minute of having powers, you're doing pretty well! I didn't stop a villain until, like, thirty minutes in, and speed is my thing."

"Thanks, I try." 

Is she just stuck with the weapon knocking beam forever now or can she remove it again? She tries to "unslot" it.

It drifts out of her internal space and away into the darkness in response to her push.

Okay so... Can she get a sensing power for diagnosis? She's not entirely sure a sprain is what's going on, and being able to direct her power better would probably be helpful, right?
