Nyx's revelation about scents and 'scents' doesn't really shock Kitty as a mechanism per se, but she's still rattled by the revelation, and the migraine-like pressure in her head.

(She's heard of Maryland before. Emily had grown up near there, hadn't she? Just don't ask Kitty to point it out on a map.)

There's something nearly imperceptible draining from the air by Nyx, too, like air slowly escaping a balloon, or water slowly circling a drain.

"I'm Kitty." Not a name she'd picked, but a name she liked; the only one she'd ever known.
