He moved forward slowly, one step at a time, until he was just beyond the reach of her blade. "Well well well, who do we have here?" The question was a probing one, and half rhetorical as well. He didn't honestly expect an answer from the girl, but the change in her demeanor had been too sudden and too obvious to miss. A moment ago she had been uncertain of herself, fumbling over his false proclamation to confess and how she should handle the situation, but now she was the very epitome of the confident warrior, completely sure of herself regardless of the opponent she faced. There was no way this was the same girl that had arrived on the scene. 

Or, he supposed, she might just be a very skilled actress. Though if that were the case, the sudden change in tactics still didn't make sense. Either way, he'd have to find out what this new side of her was capable of before it could surprise him in a much more lethal way. He hated that kind of surprise. Unless he was the one giving it, of course.

His right foot stepped back and the retracted staff in his hand came up in a loose mockery of a traditional fencer stance, and he tapped the staff lightly against the flat of her blade. 

*ting!*

Assuming she didn't then decide to launch her own "counterattack", he drew the staff back to it's starting position a few inches away from the sword blade. "Are you sure you want to do this, girl?" He didn't wait for her response before snapping the still retracted staff back toward the blade, this time hard enough to elicit an electrical jolt on impact. Not enough to cause real harm even if the sword was entirely conductive, but enough to numb the arm slightly if that was the case. Or at least give the muscles a good twitch. Either way, he would soon know if the sword had proper insulation or not. Most did not.
