 Which of the following describes Pop's attitude toward Sattell?
His name was Sattell and he had reason not to talk. The shack and the job he filled were located in the medieval notion of the physical appearance of hell. There is nothing like it on Earth, of course. Pop lived in it all alone, and in his spare time he worked industriously at recovering some missing portions of his life that Sattell had managed to take away from him. Sattell got the shakes when he thought of Pop, and Pop rather probably knew it. And Sattell turned gray and frantically denied that he'd ever seen Pop before. And Sattell went into panic when he returned. At such times Pop hardly thought of Sattell. He'd started to follow Sattell knowing what had happened to his wife and children, but it was hearsay only. When Sattell fled to another continent, Pop followed because he had some distinct memories of his wife—and the way he'd felt about her—and some fugitive mental images of his children. When Sattell frenziedly tried to deny knowledge of the murder in Tangier, Pop had come to remember both his children and some of the happiness of his married life. Even when Sattell—whimpering—signed up for Lunar City, Pop tracked him. If so, Sattell had profited by less than two days' pay for wiping out everything that Pop possessed. The sun rose very, very slowly in what by convention was called the east. Near Sattell, he found memories of times when he was a young man with a young wife who loved him extravagantly.
