⚠️ Spoiler Warning: This guide contains detailed spoilers for the entire novel. Proceed only if you've finished reading or are comfortable knowing the plot.

Summary

Proctor wakes in a cottage belonging to friends of Thea, who has been sitting by his bed reading. He has only hazy memories of the previous night—the tornado, his father's house being destroyed—and cannot recall phoning Thea to ask for help. Thea tells him he called her insistently, and Proctor admits he may have been sleepwalking, something he did often as a child. He reflects that he can no longer tell the difference between being asleep and awake.

Thea asks about Elise, and Proctor confirms that part of his life is over, suggesting she is better off without him. He then asks whether there was anything written on the walls of his father's house, and Thea says the place was blowing apart so she didn't get a good look. Proctor pieces together the telescope, the equations, and the blueprint: his father was designing a massive ship called Oranios, apparently intended for leaving the island. Thea speculates that his father, as chief legal counsel, may have known something that motivated him to plan an escape. She also notes that the blueprint was left where Proctor would find it, suggesting his father wanted him to know.

Thea reveals that when she arrived at the house, drones were swarming the area—she counted seven before the storm hit—and suggests they may have been tracking Proctor all along. She offers to let Proctor come with her to the Annex, where she has people and could disappear into the crowd, but Proctor declines, thinking of the man on the shuttle who glared at him with loathing.

Proctor tells Thea that Caeli was there last night, though he can't explain how he knows this. Thea reveals that her friend Quinn, a former data analyst at Public Safety, ran a full background check on Caeli and found no trace of her anywhere in the system—no adoption records, no transcripts, nothing at Well-Being. As far as the Central Information System is concerned, Caeli doesn't exist.

This triggers a memory for Proctor. Three times in his career as a ferryman, he was tasked with returning a new iterant to the Nursery. The first was a boy paralyzed by a shuttle who welcomed the chance to start over. The second was a girl who had become unmanageable. The third was the worst: guardians who had simply tired of parenting, telling Proctor it wasn't really their thing. The boy went limp with terror and had to be carried onto the ferry. In all three cases, the wards were wiped from the Central Information System, their documents shredded, as if they had never existed.

Proctor calls Oona at Director Brandt's office. She is formal and distant, addressing him as Mr. Smith, which signals he is in deeper trouble than he thought. She tells him there is one young person in remand—the holding area in the basement of HR where compulsory retirements wait for the ferry. Proctor realizes this must be Caeli. Oona also tells him to check his monitor before coming to the meeting. Proctor finds a reader in the cottage and checks his number: nine percent. He isn't just losing his mind—he's dying.

Character Development

Proctor — This chapter deepens his sense of fragmentation. His sleepwalking and inability to distinguish waking from sleeping states suggest a mind under extreme pressure. His realization about the Oranios blueprint shows him actively piecing together his father's hidden work, and his memory of the three return cases reveals the moral weight he carries as a ferryman—particularly the third case, which he admits he regrets to this day. The final revelation that he is dying reframes everything: his erratic behavior, his visions, his urgency.

Thea — She emerges as a loyal and resourceful ally. She came to Proctor's aid without hesitation, has people in the Annex who could help her disappear, and offers to bring Proctor with her. Her willingness to joke about her situation suggests a resilience that contrasts with Proctor's grim fatalism.

Oona — Though she appears only briefly, her formal address signals that Proctor's status has changed dramatically. Her warning to check his monitor is both a kindness and a confirmation of his worst fears.

Themes, Symbols, or Motifs

Unreliable memory — Proctor's sleepwalking and his inability to recall calling Thea or the events of the night blur the line between reality and delusion. This motif runs throughout the chapter, from his hazy recollection of Caeli's presence to his uncertainty about whether the Oranios is real.

Hidden escape vessel — The Oranios blueprint represents a secret project, a possible means of leaving the island. Thea's question about where such a large boat could be hidden underscores the impossibility of concealment in a surveilled society, yet the blueprint's existence suggests his father found a way.

Surveillance — The drones Thea observed swarming the house before the storm suggest Proctor has been under observation. Thea's comment that both of them are on somebody's list reinforces the sense of a watchful, controlling system.

Erasure from records — The three return cases and Caeli's absence from the system reveal how the society makes people disappear, not just physically but from official memory. This is a chilling commentary on the power of institutional record-keeping.

Parental abandonment — The third return case, where guardians simply tired of parenting, is the darkest example. The boy's terror and Proctor's regret highlight the human cost of the system's rules.

Mortality — The nine percent reading is the chapter's final blow. Proctor is not just losing his mind; he is dying, which reframes his entire quest.

Why This Chapter Matters

This chapter is a turning point in the novel. It confirms that Proctor's father was engaged in a secret project—the Oranios—and that Proctor himself is being watched. The revelation that Caeli has no records in the system connects her to the erased wards of Proctor's past, suggesting a pattern of institutional erasure. Most importantly, the nine percent reading transforms Proctor's situation from a psychological mystery into a race against time. He is dying, and his search for Caeli and the truth about his father now has a deadline.

Study Questions

1. Why does Proctor's memory of the three return cases matter in this chapter?

Proctor recalls the three cases because Caeli's absence from the system mirrors what happened to those wards: they were wiped from the Central Information System, their documents shredded, as if they had never existed. This connection suggests that Caeli may have been returned to the Nursery and erased from official records, and it gives Proctor a framework for understanding why no trace of her exists. It also deepens his guilt as a ferryman, particularly over the third case, where a boy was returned because his guardians simply tired of parenting.

2. What does Oona's formal address and her advice to check his monitor reveal about Proctor's situation?

Oona's shift from calling him Proctor to Mr. Smith signals that his status has changed—he is no longer a trusted ferryman but a person of interest, possibly under investigation. Her advice to check his monitor is a warning that something is wrong with his vital statistics. The nine percent reading confirms that he is dying, which explains his erratic behavior, his visions, and his urgency. It also suggests that the system may be accelerating his decline, or that his condition is a consequence of whatever is happening to him.

3. What does Thea's offer to take Proctor to the Annex reveal about her character and the society they live in?

Thea's offer shows her loyalty and her willingness to risk everything for Proctor. It also reveals that the Annex is a place where people can disappear into the crowd, suggesting that the society's surveillance is not absolute. Her comment that she has people there and could disappear implies a network of resistance or at least a way to evade the system. Proctor's refusal, thinking of the man on the shuttle, shows that he is not ready to abandon his identity or his quest, even as his options narrow.
