Fenrir resisted the urge to laugh loudly as he saw her shiver. Green as green came, just how he liked them. Yes, this would definitely be more fun than he should be allowed to have, he was already listing ideas of what to do with this pretty little thing.
He put his hands up as if giving up and stood, slowly and carefully, like she said, offering her another devilish smile as he did so. Clearly this girl didn't know who he was, or she would already have back up, which meant she didn't know what he was, and how fast he was. He strode slowly forward, faking a bit of a limp to make it seem he wasn't at his full strength, and she had less to worry about than she thought. Once he was just about beside her, he moved with impossible quickness, came up behind her and grabbed her wrists, twisting the one until the wand fell to the floor. He was able to hold her hands behind her back with one hand, while the other snaked up her body to her neck. He bent his head down to right next to her ear and inhaled loudly, smelling the fear on her. "You should really make a point of knowing who you're up against in here, sweetheart," he whispered in her ear.
