Rachel's smile fades into a hard set of her jaw and she nods. "Remember when I told you there's a time limit to morphing? More than two hours and you're stuck? People who do that, they're called Nothlits."

She tilts her head back toward the trees, voice carefully even. "Tobias is a Nothlit that regained the ability to morph. He can still be his human self, but it's just a morph. Two hours without returning to hawk and he's stuck again."
