See ghosts huh? Well this was starting to make sense. She wasn't crazy. Harley didn't think that. But she was definitely one of the people with powers like he was and now she knew his secret if she had been watching for that long. And it seemed that Miss Sarah was just a curious girl in the wrong place at the right time. Or perhaps right on both parts.
Harley grabbed her by the wrist and dragged her over to the table, shoving her forward so she could get a really good look at the body. He settled in behind her too close for comfort. "Take the scalpel," he offered it to her, "Don't even dream of using it on me because it won't do anything. I won't bleed. I'll heal right off. Now... Why don't you try it? Cut her. Tear her. Don't kill her. Not yet. If you do, I'll kill you."
And at the moment, that was the last thing he had on his mind as he perched his chin on her shoulder so he could watch her, running his hands along the flat of her stomach. Right now he wanted to watch and touch and hurt in an all new way.
