"My ancestry," she says, by way of explanation and accompanied by a fleeting smile best described as 'disarming'; he seems human (she can't be absolutely sure-- mutants and similar ilk defy her senses by not being magic, and they don't all have visual tells), which means there's a perceptible edge of anxiety to it, and maybe that's why she smiles just the way she does. Don't be alarmed, don't look at her like she's something wrong, just smile back and read the fucking book--

She doesn't want to be anybody's teaching moment about interspecies interaction. That moment of unease is something that hurts in ways she doesn't have the language to explain or argue against in any kind of nuanced way; it just makes her tired and angry and part of her is just afraid of finding that she doesn't have the energy to be angry any more.
