⚠️ 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

The chapter opens in autumn, nine years and ten months before launch. Asuka is managing to stay afloat academically, thanks largely to friends who share notes and keep her on schedule. But when Lala fails to appear for robotics class, Asuka struggles through a temperature-sensing nano bot exercise alone, finishing only half the work. Professor Wu marks her incomplete.

Later, in the dining hall, Asuka and Treena find Lala wearing a long medicated skin patch across half her face. When Asuka asks what happened, Lala replies, “America happened.” Treena, who views Lala as a rival for the U.S. seat, makes a sarcastic comment, and Lala nervously asks Treena not to post anything about her condition. Lala then asks to eat alone, saying she doesn’t have the bandwidth to help with Asuka’s problems. Asuka, embarrassed, leaves.

Asuka heads to her first simulation team session. Outside the sim building, Ruth tells her that Lala and Winnie were attacked by racists. Winnie, coming from cricket practice, fought back with her bat and sent one attacker to the hospital; a delivery worker then pulled a gun on the attackers.

Inside, Coach Li runs a flooding-room exercise. The team is locked in a room that fills with real water. Asuka initially panics, flashing back to Luis drowning, but steadies herself by counting the pearls in her mother’s jewelry box. She takes charge: she tries to pick the lock, stuffs a curtain under the door, and eventually discovers an air vent in the ceiling behind a bookshelf. With Ruth’s help, she moves furniture under the vent, unscrews the cover, and helps all ten teammates escape through the ceiling as the water reaches the top of the chamber. At one point she nearly gives up, feeling heavy and tired, but she hears Luis’s voice asking if she’s going to give up, and she pulls herself up.

After escaping, Asuka vomits against the concrete wall. Ruth follows her, compliments her, and comforts her, then walks her home. Asuka realizes she isn’t dreading the monthly simulations—she feels defiant, believing make-believe can’t hurt her after everything she’s been through.

Later, Asuka checks the sim team rankings: her team scored nine out of ten. She messages Lala, who doesn’t reply.

Character Development

Asuka demonstrates significant growth. She moves from a passive, struggling student to an active leader in the simulation. Her ability to direct teammates, search for solutions, and ultimately save everyone shows resilience built throughout the story. Her internal battle with despair, triggered by memories of Luis drowning, reveals the depth of her trauma, but her decision to push through shows determination. The chapter also shows her vulnerability: she vomits afterward and cries in front of Ruth, but she accepts comfort, which is a form of growth.

Ruth emerges as a surprising ally. Despite their earlier conflict, she is supportive during the simulation—helping Asuka move furniture, towing the girl who can’t swim, and comforting Asuka afterward. Her promise not to tell anyone about Asuka’s breakdown suggests developing trust.

Lala is shown in a vulnerable state. The medicated patch and her request to eat alone indicate she’s dealing with the aftermath of a racist attack. Her comment “America happened” suggests disillusionment with the country she’s representing. Her refusal to engage with Asuka’s problems shows she’s overwhelmed.

Treena is shown to be competitive and somewhat dismissive of Lala, viewing her as a rival for the U.S. seat. Their dynamic highlights the tension between competition and friendship in the candidate program.

Themes, Symbols, or Motifs

Water is the central symbol. The flooding simulation directly echoes Asuka’s trauma of watching Luis drown. Water represents both danger and the possibility of survival—Asuka must confront her fear to save herself and her team.

Pearls appear as Asuka’s coping mechanism. She counts the pearls in her mother’s jewelry box to calm herself during the simulation. The pearls represent her connection to her mother and a grounding technique that helps her manage panic.

Racism and xenophobia are directly addressed through the attack on Lala and Winnie. The chapter shows that prejudice persists even in a program meant to send humanity to the stars. Lala’s “America happened” comment suggests broader disillusionment.

Survival and resilience are the chapter’s core themes. Asuka’s ability to lead her team through the simulation, despite her trauma, demonstrates that survival is her strength. Her thought at the end—surviving is what she’s good at—encapsulates this.

Friendship and support are shown through Ruth’s unexpected kindness and the earlier note that Asuka’s friends help her keep up with classes. The chapter contrasts this with Lala’s isolation.

Why This Chapter Matters

This chapter is pivotal. It establishes Asuka’s capability as a leader under extreme pressure, which will likely be central to her role in the main plot. It deepens the theme of racism and xenophobia, showing that prejudice exists even among elite candidates for a mission to save humanity. The chapter also develops the relationship between Asuka and Ruth, transforming a rivalry into a tentative friendship. Finally, it reinforces Asuka’s core identity as a survivor, setting up her resilience for the challenges ahead.

Study Questions and Answers

1. How does Asuka’s experience in the flooding simulation reflect her past trauma, and how does she cope with it?

Asuka’s panic during the simulation is directly triggered by memories of Luis drowning. She copes by counting the pearls in her mother’s jewelry box, a grounding technique that helps her steady herself. She also hears Luis’s voice asking if she’s going to give up, which motivates her to pull herself up into the vent. Her coping mechanisms—counting, focusing on a task, and drawing on her memory of Luis—allow her to function despite her fear.

2. What does Lala’s comment “America happened” reveal about her character and the broader themes of the novel?

Lala’s comment, made while wearing a medicated patch after being attacked by racists, reveals her disillusionment with the United States, the country she’s representing as a candidate. It suggests that the promise of opportunity and equality is hollow for people of color, even in a program meant to save humanity. This ties into the novel’s broader critique of racism and xenophobia, showing that prejudice persists even in the most elite and supposedly forward-thinking institutions.

3. How does the relationship between Asuka and Ruth change in this chapter, and what does it suggest about the importance of alliances?

At the start of the chapter, Asuka has been avoiding Ruth after a conflict. But during the simulation, they work together effectively—Ruth helps Asuka move furniture, tows the girl who can’t swim, and boosts Asuka into the vent. Afterward, Ruth comforts Asuka, compliments her, and walks her home. This transformation suggests that shared adversity can forge alliances, and that Ruth may become a trusted ally for Asuka in the future. It also shows that Asuka is capable of accepting help.
