The Labyrinth was enough to confuse her senses – Vaughn's steps seemed to echo, and she didn't realize how close he was until he was nearly stumbling over her. Every muscle in Nora's body went tense, her eyes flicking up to fix the intruder (from her point of view, at least) with an intense stare. He wasn't familiar, but no one at the Cirque was really familiar yet, aside from Zane.

He didn't smell like food, at least. This wasn't the scent of warm, living blood – not an entirely human scent. And that was a good thing, because she didn't think she could have kept her cool if it had been a human stumbling on her impromptu hiding place. Zane would probably have been unhappy if she had ripped out the throat of a random patron.
