 What is the dynamic between Tennant and Dana?
Dana was lying under a tree near the door, stretched out on a sort of deck chair with her eyes closed. Above it her comely face was sullen beneath its sleek cocoon of auburn hair. He could sense the restless stirring of the woman within Dana, just as he could feel the stirring toward her within himself—desire that both of them loathed because it was implanted within them by their captors. They entered the house, which had no roof, continued to move beneath a sky that glowed with light which did not come from a sun or moon. Eudalia, who had borne twin girls recently, was lying back, newly thin and dark of skin and hair, smoking a scentless cigarette. Eudalia had been a female foreman in a garment-cutting shop before being captured and brought through. Tennant wanted to put an encouraging hand on her shoulder, to say something that might cheer her up, for she was by far the youngest of the three female captives, barely nineteen. It arrived before the meal, materializing against one of the seven walls of the roofless chamber. Tennant watched the girls as a sweet-voiced crooner began to ply an unfamiliar love lyric to a melody whose similarity to a thousand predecessors doomed it to instant success. Dana stood almost in the center of the room, carmine-tipped fingers clasped beneath the swell of her breasts. Somehow it brings things closer...." Tennant caught Dana looking at him and there was near approval in her expression—approval that faded quickly as soon as she caught his gaze upon her.
