an eight year old girl with brown-flecked white wings, looking dismayed and lost.
Unexpected, perhaps, but not necessarily unprecedented. These terribly rude fellows, for instance, seem to have some idea of what she might be, even if it's not the right one. Unfortunately, they seem more interested in jeering and attempted violence than explaining exactly what a mutant is and why they think she is one.
She is not immobile; they can knock her around in the course of finding that out. She is upset and disoriented by the experience and the mussing of her hair and feathers and she screams and hits back.
She's very strong.
"DO NOT BE HITTING," howls the little ostensible mutant. "IT IS NOT HOW FIXING PROBLEMS!"
"That's very good advice," says someone from behind one of the men blocking Pen's view. "I suggest you lot take it. Before I decide not to."
Pen is a little too occupied to be listening closely to this person. She socks a hooligan hard in the arm trying to get him off her.
"That...isn't a reason to be less impressed with my threats of violence. I'm appealing to your self-preservation, you ninnies, not your nonexistent morals!"
Steel moves in improbable quicksilver loops, wrapping itself around any of Pen's assailants who don't get out of their way quickly enough. The rest either flee or are taken out of the picture by a blow from some less-obvious chunk of metal that leaves them gasping or groaning on the ground.
Pen cocks her head and brushes grit off her leather pants. "A magic," she observes.
"Um, no? I'm a mutant. Like you," she says, gesturing to Pen's wings.
"I mean, sure, you absolutely look like an angel. But baseline humans just don't get born with extra body parts."
"Am angel like Mommy and sisters," says Pen. "Not a mutant. That some other thing."
"Glad I amuse you. So where is your family, anyway? Did these creeps kidnap you? Do you need help getting home?"
"Do need help home but a metal magic probably won't do thing. Door is break, family in Samaria but door go here."
"...If a door is broken, I think I would actually be above-average useful at fixing it. And it's not magic, it's magnetism. Like what sticks your grocery lists to your refrigerator."
"...It's...what you put food in to keep it from going bad? How do you not know what a refrigerator is? Are you Amish or something?"
"...You know what? I am not qualified to handle this. Do you know what the Xavier Institute is?"
