"Odd. Very odd. That... suggests some things about how we handle this. It's possible to find foster or adoptive parents who won't just treat you like a slightly precocious Earth twelve-year-old and exclude you from any decision where your input is inconvenient, but rare, and we're going to need to finesse things a bit, depending on what you want to do from here."
She is not sure she trusts normal foster parents to raise this kid.
Possibly she shouldn't believe the alternate world story so quickly, but all that ID is pretty convincing.
The cops are going to be trouble. They're the best way to get social workers for placement quickly and to get Audrey and her... other selves? The other girls in her head? Facets, she called them? To get them into the system and get a social security number, but unless they get lucky with which cop they get, the otherworldly stuff is going to turn this into a circus.
And the cops and social workers just straight-up can't be told about the facets, not until Sable learns more about it all herself. It sounds like it's normal on their world, and that means that there are proper ways to handle it that America's mental health system will fuck up badly if given the opportunity.
Well, good thing she's got this week off.
