"Our leader will provide for your needs."

That's the most ominous offer of free stuff she's ever heard. Possibly the translation's fault. "That's very nice of you. Still, I'd like to help out where I can rather than freeloading. Is there somewhere I should talk to about getting a legal identity?"

"You will be provided one, yes."

"Okay, good. Any reason I shouldn't go do that now? Or I can just wander around a bit if I need to wait for something. Oh, maybe you could give me directions to a library?"

"You are not free to go."

"Huh? Why not?" And who are you, anyway, when you were just a random person dealing with a stranded time traveller it wasn't important but now that you're claiming authority it is.

"Our leader has expressed interest in you, and all modified humans must be in service to the nation."

"Who is your leader? Are you part of the government?" What sort of messed-up future has she wound up in?

"Our leader is Premier Marian Yashagoro. I am the chief of police of district eighty-seven."

So the criminals are the government, or at least think they can convince her of such. Figures.

"What do you want? In the short term and the long term."

"Personally? I'd like to follow my orders without resorting to violence, and retire eventually to somewhere nice. As a state? We seek the flourishing of our human population. Premier Yashagoro also seeks to know all things."

"Those are good things to want," she says in a conciliatory voice. "Can you tell me more about what you expect my future to look like?" (It looks like learning a lot and then running off to somewhere else at the first opportunity, if she can manage it.)

"We will test to see how your talents are best turned towards the common good, and then you will use them in service of that good."

"That sounds good." And she's going to want to know what her comparative advantage is when she runs away to somewhere not run by kidnappers. Though she should probably pretend to be worse at things than she is, just for the sake of knowing things they don't. Relatedly, "Can I get something to eat first, though? I hadn't had breakfast when I had the magical accident."

"Of course. We take care of our assets."

And food and water - fairly plain, tasting off compared to the food Margaret's used to - can be brought.

She wasn't expecting future food to taste familiar, but she was sort of expecting it to taste better than this. Hopefully this is just her captors failing to make an effort, rather than extreme stagnation in food technology. But it's free food and she can tell it isn't drugged, so she eats it.

The police chief leaves for a time, and when she returns - after Margaret has finished eating - she commands Margaret to follow her.

She follows. They aren't treating her like they've realized the full implications of her powers for self-defense, which is good, because she wants to keep those possibilities theoretical as long as possible.

The possibilities do, indeed, remain theoretical for quite a while - though their leader despite apparent curiosity does avoid directly meeting with her. There's intense curiosity about the limits of her powers, when they activate, how dangerous is 'danger', if they have a person involved administering a test that the administrator is convinced is dangerous but isn't actually will it trigger for instance...

And they put her to work. Mostly, they find, she's really good at keeping ships doing high-risk maneuvers from blowing up. Which means they can push the envelope on experimental hyperspace travel, and move 'workers' around faster - they're having trouble with raiders, is the rumor, though the supervisors are fairly good at keeping 'workers' from talking to each other.

But Margaret, if she's patient and watchful and diligent, will get a sliver of an opportunity, during one of the larger and more complicated movements of 'workers' (they're barely even pretending to not be slavers with this particular spaceship) to seize control. She's on the bridge near-constantly after all, and the captain's worked with her enough that he's forgotten he can't trust her...

Margaret plays along, outwardly, but all her attention is focused getting ready to run. She sees how they treat the people they find less interesting or less useful, and resolves to make some trouble on the way out if she gets half a chance. Maybe she can give someone else an opening too.

She lets the experimenters see how good she is at detecting physical danger, but conceals most of her ability to detect hostile intent. No matter what the experimenters believe while running the tests, she's always detecting the presence or absence of a real threat.

Guiding ships through hyperspace would be an amazing job if not for who she was working for. Between the danger sense and the advance perception, she always knows just which way to jink to reduce the stresses of the higher hyper bands. She gets prophecies too, more days than not; some of them are advice for ship captains (recommending slower and safer routes, and perhaps ignored); others are for her ears only. She manages to filch a couple things that might be useful: an extra ration bar here, a roll of duct tape there. It's easy to hide things in pockets that can seal themselves shut. She looks like a harmless, cooperative little navigator. And she waits.

Until the day when the bridge is just her and the captain and the first officer, and they make the mistake of standing too close too each other where she can come up behind them. Suddenly her hands hold the ends of rubber straps, wrapping around their eyes and noses and filling their mouths so they can neither give alarm nor draw a breath. 

They go down quite easily, being entirely unenhanced humans with no real training in hand-to-hand.

Margaret has no training either, just a lot of pent-up anger and the power of accessories. 

She also doesn't have training in flying the ship by herself. Once she's made sure her opponents are unconscious and tied them up with the duct tape, she heads to the internal control board. If she can seal off the engine room from the rest of the ship, then a majority of the local ability to do things will belong to people with a reason to support this hijacking. (In the back of her mind, she remembers The Martian and wonders if this technically makes her a space pirate.)

Sealing the engine room off works, though it'll take her a few minutes and perhaps a check of the manual.

The ship isn't in danger and the officers went down without giving the alarm; she can spare the time to check the manual and be sure she's doing this right. 

Once the engine room is sealed, though, it's only a matter of time (and not much time) before someone there notices it. She needs to secure control of the rest of the ship by then.

Margaret flips on the main intercom, the one used to warn all aboard to brace for takeoff of hyper transition. "Prisoners!" she declares. "This ship has been hijacked by one of your own! Rise up, take down your guards, and we can all be free within the hour! They can't stop all of us! Guards, surrender if you value your lives above your masters' profit!" Then she leaps to stand to one side of the door, shield on one arm and the other ready to take out anyone bursting in.

There's a pause - and Margaret won't be able to hear any mundane sounds of a struggle through all the metal - 

And then three people burst in, all wielding assorted guns.
