Hearing that hitch in her breath was beautiful, because it meant one thing. That resolve of her to stay strong, to not let him break her was slowly cracking, and it was his goal to make it shatter completely. Crane had used criminally insane individuals in Arkham, innocent people throughout Gotham, Batman himself, slayers, werewolves... The list was long, but there was one common denominator in all of them: He always made them crack. He always made them break, and that thirst was what was driving him right now. It wasn't even really thirst, it was more like a craving. Something that he hadn't quite been able to satisfy in Gotham, on the road, or even while working for Dick Roman. It was his constant, his drive, and right now he needed this.
He needed to make her crack.
Her shouting to let her out was another step closer, but it wasn't enough. Of course it wasn't. Crane wasn't particularly satisfied with just screaming, because that part was easy. Anyone could make someone scream, all you had to do was play the part right. What he had in store for her... Only he could do it, and he would show her. Crane had no idea that she was a mutant, hadn't taken the time to really investigate beyond the fact that he knew she wasn't a vampire. He just knew that he was ready to play.
Once the syringe was prepared, he walked back to her. "Tsk tsk tsk... You shouldn't be so afraid. This will help you. This will help you get to know yourself so much better than you think you do." With his free hand, he reached for her neck to hold her in place. "Before we begin, why don't you tell me your name. I will find out one way or another, but I will give you a chance to do this yourself. What's your name?"
