Moneo returns from inspecting the Citadel perimeter during a heavy rainfall, noting the contrast between the weather controllers and Leto's well-known aversion to moisture. After changing into dry clothes, Moneo descends into the crypt to discuss the impending peregrination to Onn with the God Emperor. Despite his severe exhaustion, Moneo maintains his dutiful vigilance, though he privately struggles with the heavy burdens of administration and his impending mortality.
During their audience, Moneo questions Leto about the newly arrived Duncan Idaho ghola provided by the Tleilaxu. Leto reassures him that the new duplicate is untainted and discusses his intricate breeding program, which aims to guide humankind toward long-term decision-making. Moneo attempts to understand the rules and evolutionary mechanics governing Leto's choices, leading the God Emperor to describe himself as a predator that improves the human stock without malice. Moneo tries to reconcile this chilling metaphor with his own perspective on infinity and survival.
The conversation shifts toward Moneo's daughter Siona and her upcoming test. Moneo expresses deep anxiety for her safety, fearing she lacks the maternal preparation he once received. Leto dismisses these fears, insisting that Siona possesses the necessary strength and must be awakened to her duties as an Atreides. Leto confirms that Siona will soon be introduced to the new Duncan after she completes her trial. Overwhelmed by fatigue and emotional strain, Moneo eventually departs without formal dismissal, comforted only by the thought that Leto will understand his weariness.
