Well, she had been a little sloppy. Though she couldn't see why the humans would care for their destitute now when they were the ones who left them to the streets for a slower death. In this light, her actions were a sort of kindness.
She'd keep her senses open for this scout - hunt them down if she must, whatever was needed to ensure she would not be followed back into the city. It wouldn't be difficult now that she was made aware of it. Those that looked at you always left a mental trace leading back, no matter how well hidden they were.
Her laughter came musically again at his final words, trembling in their delivery and perfumed with impending death. She reveled in the scent of it.
"You can't determine age based on observation," she chided, shaking her head. "I am well over three thousand," her eyes bored up into his now, a hungry smile on her face as she delivered the lie he would never be able to catch. Just then she thought maybe of tasting him, tantalized by his unexplainably attractive scent, and drew in close as if to do so. A single finger traced the side of his neck, cracked with dried gore.
She inhaled sharply. "You will crawl back to your people - if you can," her voice darkened and she reached into his mind again to speak like a terrifying echo reverberating in his skull, "Tell them that none of you have the slightest idea of who you are fucking with." In a blink her hand was around his throat, nails biting at skin. "Stay the fuck away from me." His throat was quickly released and she raced off into the night with inhuman speed.
It would seem, to Nox, that she'd vanished into the ether.
