Into a feisty goth-tomboy.

You look her over speculatively.

3: Transformation is possible, but if maintained for over 24 hours, it will be permanent.

Does it really work? Can you change this chick's body?

Best to try it on something simple first. Your attention goes to her long brown hair first. "I wish you had black hair. Midnight black," you say.

Katherine's hair darkens from brown to black, right before your eyes.

"Wow," you say. Knowing magic is real is one thing, and seeing it affect Katherine's behavior is another, but seeing it work right before your eyes? That's something else.

Katherine examines a strand of her hair. "Huh," she says, nonplussed, but not really upset. "I've always wanted to try black, but I always liked my old hair color better. I guess can try rolling with this for a while. You're going to change me back at some point, right?"

"I'm not sure, we'll see," you say.

Katherine frowns. "If I want to go back I can always find something that matches a photo and dye it that way," she says, calmly rationalizing the situation.

You're having way too much fun to stop now though, even if it's inconvenient for the goth chick. "How about we give you a haircut to match?" you ask.

She lifts her hands again. "Wait, it took me forever to get my hair this -"

"I wish your hair was cut in a super cute pixie."

Katherine's hair severs and falls to the ground, but disappears before it even hits the pavement; she's left with exactly what you described. A super cute page-boy cut pixie, with feathered bangs.

She feels at her head, looking vaguely disappointed. "Man. I look like a boy with short hair," she gripes. "I'm not that kind of lesbian. You're ruining my look, dude."

The sense of power is too much to fight. "I wish this was your look," you say with bated breath. "I wish you were a total tomboy -- always have been and always will be."

"Wait," says Katherine, but it's too late.

With your wishes, the world shudders and goes out of focus. A second later it snaps back to normal.

Standing in Katherine's place is a slightly different Katherine.

Katherine's hair is still black and short, but now she has dark green streaks of green dyed against the black. Her cute black shirt's been replaced with an equally black tank top, and a pair of fingerless black biker gloves have appeared on her hands. Lower, her short leather skirt's been swapped out for a pair of tiny gray shorts. Likewise, now her fishnets are a pair of raggedy tights, while her stylish black boots have been replaced by a clunkier, more militaristic pair.

At the end of it all, Katherine's still shielding herself as if it might help, eyes squeezed shut

"I must've changed a lot more with that one," you say, looking her up and down with approval. "Nice look."

Katherine risks a peek, then looks down at herself. She doesn't look surprised or even curious. "You change your mind?" she asks. " I thought you said you were going to change me up a bit?"

"I did. I made you a tomboy, didn't I?"

"But you didn't do anything?" she asks. "I've always been like this."

"Katherine, you were wearing a skirt a second ago," you say.

"It's Kat," the goth chick corrects you. "Only my mom calls me Katherine. And I think I'd know if I was wearing a skirt. I only own one and I haven't worn it in years."

You think through your wording. I wish you were a total tomboy -- always have been and always will be - did the collar grant your wish literally? Did you actually change time? Or was this new version of Katherine - Kat - simply fooling herself that her wardrobe matched a new set of memories that didn't line up with reality?

"Look dude, we had a chat, and I don't care if you have wishes or whatever. I'm going home now," she says. Then she pulls a set of keys out of her pocket and heads out toward a car.

You thumb the retract button for the collar.

Kat jerks back toward you by her neck, spluttering and almost falling over. "The fuck!? Let me go, man."

You let go of the button once she's right next to you again. "I wish you'd come home with me instead," you say.

Kat rubs at her neck and gives you an angry look. "I'm coming home with you, fine. But you need to tell me your name, at least."

"It's Roger," you say.

"Well, Roger, before you get any weird ideas," says Kat, "I play for the other team. And if you try anything, and I can tell you're thinking about it, I'll make you regret it and get you tossed in jail forever."

"You know I can make you do anything I want," you point out.

"Only if you wish for it," Kat counters firmly, folding her arms like she played some big move on you. "I may be small but I could kick your ass if I had to. Sure you made me fall out of love with my girlfriend, but I'm my own woman and I make my own decisions about my body and my love life - that's none of your fucking business, whether or not I spend the night at your place."

You guess you did wish for Katherine to ignore how the collar made her do things, and to not think it was weird that you were making wishes and accept any wish you could make. That doesn't really leave much room for active resistance. Kat won't fight any of your wishes - past or future - but it doesn't mean she won't fight you.
