It was beginning to become obvious to Draco that she was eager for more than just the chance to draw blood. But that was good; he much preferred someone driven to impress him than someone with a simple bloodthirst. He was, for the most part, done with his own attempts to impress people; it was now expected of him to do what was required, and do it well. He didn't particularly want to raise expectations for himself any higher, since they were considerably higher than he was sometimes entirely comfortable with already. All he cared about was fulfilling expectations, because failure was not an option.
He still recognized that motivation in Melinda, though. It could make her very useful to him, especially if she could take his fairly simple instructions and get the information he needed.
Although the tap of her wand on his shoulder made the man flinch, the question seemed to have the effect of reminding him why he'd dared to defy them in the first place. His expression hardened, and he shot a glare at Draco, who narrowed his eyes, and then at Melinda. "They deserved it."
