“That man won’t quit as long as he can still draw a breath—none of my teammates will. Me, I’ve got a different problem. I feel like I live in a world made of cardboard, always taking constant care not to break something, to break someone; never allowing myself to lose control, even for a moment, or someone could die. But you can take it, can’t you, big man? What we have here is a rare opportunity for me to cut loose and show you just how powerful I really am.”
