[SPOILER ALERT] What does Graff mean at the end of Orson Scott Card's short story, "The Polish Boy"? Captain Rudolph says, "All right, now I get it, you're giving him the wish of his heart, today. And then, long after he's forgotten, you're going to pop up and ask for his firstborn child." Graff replies, "Only I don't have some stupid loophole that will let him get out of it if he can guess my name." What does he mean by that? Is he referring to the written tests used with his siblings and him, when John Paul was able to wittily manipulate his examiners? Or is he referring to something deeper, something else?
