Moneo sits in his workroom surrounded by paperwork and administrative tasks as he prepares for the upcoming wedding of the God Emperor Leto and Hwi Noree. He dismisses Nayla after confirming that she will attend the ceremony armed with a lasgun. Left alone, Moneo reflects on his daughter Siona, who has survived the desert ordeal and whose rebellious nature has now been tamed by the Golden Path, mirroring his own past caging and burdens. He summons a young Fish Speaker acolyte for water and asks her to bring Duncan Idaho to the workroom, choosing to leave the door open so he can listen to her play the biwa lute.
When Duncan Idaho arrives, he and Moneo discuss what his predecessors failed to learn, touching upon themes of Fremen philosophy, trust, and the true nature of the God Emperor. Moneo reflects on a stormy sea voyage from his youth, realizing that the God Emperor is both the destructive storm and the vessel itself. Moneo challenges Idaho on how he builds relationships and chooses companions, arguing that Idaho lacks true trust because he allows no room for goodwill or differences.
Siona enters the room wearing the black and gold uniform of Fish Speaker command, her face still bearing the physical scars and exhaustion of her desert survival. She confronts both Moneo and Idaho, mocking her father's talk of trust and expressing bitter resentment toward her new role in the God Emperor's service. Idaho listens intently, recognizing her position while trading sharp remarks with her.
Moneo interrupts their bickering to announce his plans for them during the wedding festivities, stating that he wants them both out of the way and directing them to a remote Museum Fremen village called Tuono near the Sareer. Siona initially resists and questions the decision, but after learning that Nayla will escort them, she abruptly accepts. Idaho, after brief hesitation and recognizing they have little practical choice, agrees to the arrangement as well, while Moneo maintains that his primary intention is to keep them both alive.
