Dinah pointed "up" and allowed Rhys to reach out with his free hand and grasp her gently by the wrist, arranging her hand so that the finger was several inches away from the vertex of the U-shaped bend in the chain. "Here goes nothing," he said, and began to pull the chain toward him—away from Dinah. Contrary to what she’d expected, the bend started to propagate away from Rhys, and toward Dinah, until finally the free end hurtled around, like a whip cracking, and made several quick turns around her finger, snaring her. "Gotcha," he said, and began pulling her toward him.
