There's something vaguely funny about all of this -- this elaborate (and wrong!) explanation for things she's been witness to her whole life. The idea of different worlds doesn't even occur to her right then; clearly there's fey where he's from, and he's just as clearly misattributing magic to... demons.

It's the last thing she'd have expected to hear.

"I'm one of those stolen children," she offers, because he's clearly referring to changelings, right? "So yes. I know some fairies."
