As in the beginning of the story, Saul tries to imagine himself back on Earth to no avail. He finally understands that, in his greed, he has lost any hope of being freed from his Martian hell until he, like all the others, dies. The possibility of escape—even just mentally—is buried with Mark. That Saul ends the story by sleeping suggests that, without the chance for connection or mental stimulation, his life is effectively already over.
