He did as she asked, and promptly dropped her with no warning, but held onto her wand. "Better?" he asked. Once she had righted herself though he grabbed her roughly by the arm and dragged her with him towards the edge of the island. There was nothing but angry sea below, and he held her right at the edge.
"Now, there's a few ways this can go, sweetheart," he started, having to yell a little over the crashing of the waves. "I have you wand at the moment, and I'm no expert, but I'll hazard a guess that if I just start waving it at you, bad things could happen. I have no training, you see, I don't know how to use these - sticks." he glanced at her wand with a look of disgust on his face. "If you struggle, I can just throw you over now and be done with you, don't think you'll survive that fall, not without your stick." He pushed her over the edge a little while still keeping a firm hold on her so she could see he was serious. "If you decide to cooperate, I'll let you live. All you have to do is get me out of here and to the Forbidden Forest, and we'll see how things go from there, but I won't kill you." He rather liked the idea of having her around, she was at least pleasant to look at. And when the next full moon came, he'd make her one of his pack officially. "The choice is yours, but choose quickly, I'm sure by now someone has found the bodies."
