Duke, on the other hand, couldn't keep his eyes off Nathan. It was surreal, seeing the man chained down and completely out of his mind like that. Even knowing how terrible the troubles could be, his vague memories and minor run-ins so far couldn't prepare him for -- this. This drooling, groaning, flushed and sweaty mess. This total breakdown in everything that made Nathan human.

Duke laughed along, humoring him. "That's a good one."

Nathan flung himself against the chains again, panting. "Just using people. . . ." He laughed, bouncing in place. "Like you always do. Plan on using Audrey, too?"

Duke took a deep breath through his nose, reminding himself not to rise to Nathan's level.

Nathan kept laughing. "Of course you are. Of course you are, that's what you do! You and your little whore --"
