Paul’s increased powers of foresight reveal the terrible truth of his and Jessica’s familial relationship to the man who has just killed Duke Leto. Bene Gesserit superiors hid Jessica’s paternal identity because they hoped to inbreed her daughter with Feyd-Rautha Harkonnen to produce a child who would be the Kwisatz Haderach. Finally, too, the narrator confirms that Paul is, in fact, Muad’Dib, the subject of Princess Irulan’s many historic texts.
