"Well, we can try." Jack said thoughtfully, nodding. "But I'm pretty sure I know how that goes. I'm not real fond of the ending it'll provide."
He didn't think this girl was a ghost. He'd never seen anybody be able to do things like she was doing right now, but that didn't mean much. He'd lived in a world where a man with enough money had become a bat and the woman below him had once had the ability to create a scream to shatter most things. Now he lived in a world where people could do all kinds of interesting stuff.
"So what do I gotta do to break you out of this little ghosty state? Shock you? Do something to shake your little world? Throw things at you? Water? If I splash water on you, will that work? Oh, what about puppies? Are puppies your weakness?"
The squirming caught Jack's eye as he looked around the apartment for things that he might be able to throw at the half visible girl, and he turned. The knife arched down and slid through the skin and muscle to land neatly in Dinah's shin. He brought it out again with the tip missing, broken off in bone.
"Stop." He said, not even caring about the broken blade. It would just give him more interesting cut marks, that jagged end. Jack moved around to the other side of Dinah, putting the damsel in distress between himself and the newcomer, dragging the now more cruel knife end along her flesh as he did so.
"So do you think you can get to me before I do something like... stab her through with this thing? Do you think you can get to me before I jam it into her eye?" He smiled, wide and wicked. "Oh I like that one. You get to me, or she loses an eye. Yes."
