"Oh, them. They're downstairs in the lobby. A couple civvies, but mostly cops. Didn't put up much of a fight, if I'm honest. I felt bad about that. Figured I'd come turn myself in." 

He remained facing away from her the entire time he was speaking, his hands behind his head like she'd told him to place them, his feet shoulder width apart and his body relaxed. Or as relaxed as he could be, at any rate. He was getting kind of tired of these little mind games. If she hadn't moved, and from the sound of her voice she hasn't, she was a mere eight feet away from him. His staff was six when fully extended, and his arm could make up the difference. He was starting to doubt that his ploy would work, she just kept getting more cautious the more she talked, so he decided to opt for a more active approach.

Without doing anything prior to give himself away, things like saying a few witty words to the tune of "on second thought" or "you know, I've had a change of heart", he spun back to face her, left hand gripping the end of his staff as be moved and pulling it free of his back. It swung out in a horizontal arc as it extended, aimed for the girl's right hip. If it struck, it would be hard enough to crush all the affected bones then and there, and the electrical charge it would generate would be more than enough to kill a human.
