Summary

The chapter opens in the USA, eight years and eleven months before launch, as Asuka begins her second year at EvenStar. During her first year, her simulation team held the top spot, and she never failed a single sim. Her teammates Ruth and Treena joke about Coach Li's brutal exercises, but they all genuinely respect her because she teaches them techniques for managing panic and taking care of their mental health—rare among the adults at EvenStar.

Coach Li announces that team compositions will now change monthly at random. Ruth is glum about being split up, and Treena teases her. Asuka heads to her first sim of the year and is surprised to find a bus waiting—the first time they've been taken off campus for a simulation. Gabriela Ota saves her a seat, and Becky McMahon sits in front of them.

Asuka mentions her history test went terribly. McMahon criticizes her for skipping lectures. Asuka gets defensive and launches into a bitter rant about wars, pandemics, extreme weather events, rising sea levels, and the ten billion people who will die from humanmade problems. This outburst is triggered by her mother's social media post that morning, which argued that building an interstellar ship wastes precious resources that can't be replenished. Asuka wants to counter that the mission uses nuclear material from thousands of warheads, but she knows there's no arguing with her mother.

Gabriela notices Asuka is upset and asks if she's okay. Asuka admits she doesn't know what she's doing there. Gabriela says everyone feels that way, including herself. Asuka briefly wishes Gabriela were also a candidate for Japan so they could commiserate after national team meetings.

The bus stops at a simulated seaside village. Asuka has switched out Luis's old vizzy for a newer model that can process more data. Gabriela asks if Asuka meant what she said earlier about trying to leave the world. Asuka says yes—they're here because they're trying to leave. Gabriela disagrees, arguing the mission isn't about giving up on the world but about making more of it. If the problems were unfixable, she says, they wouldn't deserve another chance—and they do.

At that moment, the ground begins to shake. Asuka and Gabriela recognize the signs of a tsunami. Asuka points to a hill about half a mile away and urges everyone to run to higher ground. McMahon questions her reasoning, suggesting the sim might be about a monster coming from the hills instead. Asuka explains that when she lived in Japan, she was taught that an earthquake means getting away from the ocean immediately. McMahon dismisses this as personal context that doesn't apply to the sim. Asuka runs anyway. Gabriela shouts for others to follow. Only half the group does.

A great wave washes through the town. When they remove their vizzies, they find themselves on a hill behind campus. The ocean was the campus lake, the earthquake was caused by a mechanical platform, and the bus had driven them in circles to disorient them.

Coach Li debriefs them at picnic tables by the lake. She says that if they're selected for the mission, they'll have no one but each other—Mission Control can give direction, but ultimately it's just them. She acknowledges Asuka survived but says that's not the point. Becky raises her hand and says the point is maximizing mission success through teamwork. Asuka and Becky argue: Asuka accuses Becky of convincing six people not to run, and Becky says Asuka left them behind. Coach Li interrupts, saying the mission isn't about individual feelings or whether they like each other, and that failing to understand this will let everyone down.

Key Events

Coach Li announces that team compositions will change monthly at random.
The first sim of the year takes place off campus in a simulated seaside village.
Asuka and Gabriela discuss the mission's purpose: leaving the world versus making more of it.
An earthquake triggers a tsunami; Asuka runs to higher ground, but only half the group follows.
The simulation ends with the wave washing through the town; the group is revealed to be on campus.
Coach Li's debrief emphasizes teamwork over individual survival, and Asuka clashes with Becky.

Character Development

Asuka shows her instinct for individual survival and her self-doubt about belonging at EvenStar. Her conflict with her mother's environmental views weighs on her, and she wishes she had a fellow Japan candidate to commiserate with. Her Japan upbringing gives her practical knowledge that saves her in the sim, but that same instinct isolates her from the group.
Gabriela Ota emerges as a hopeful counterpoint to Asuka's despair. She believes the mission is about creating more of the world, not abandoning it, and she tries to reassure Asuka that they are both good enough.
Becky McMahon is confident and dismissive, but she correctly identifies the simulation's lesson about teamwork. Her smugness in the debrief fuels the conflict with Asuka.
Coach Li is a mentor figure who teaches both technical skills and mental health practices. Her disappointment in the debrief reveals the mission's core value: collective success over individual achievement.

Themes, Symbols, or Motifs

Teamwork vs. individualism: The simulation's design—a tsunami that requires group coordination—directly tests whether the students can work together. Asuka's individual survival instinct, while effective, is not the point.
Environmental crisis and generational conflict: Asuka's mother's social media post about resource waste represents a broader societal debate about the mission. Asuka's frustration with her mother mirrors the generational divide over how to respond to the climate crisis.
Hope vs. despair: Gabriela's belief that the world deserves another chance contrasts with Asuka's grim view that they are simply trying to leave a dying planet.
Self-doubt and impostor syndrome: Asuka's feeling that she is an off-brand version of what people wanted, and her wish for a fellow Japan candidate, reveal her insecurity despite her sim record.
The vizzy as a symbol: Asuka's switch from Luis's old vizzy to a newer model suggests both technological progress and her growing distance from her past.

Why This Chapter Matters

This flashback establishes the central tension of the novel: Asuka's individual survival instincts versus the collective demands of the mission. It introduces Gabriela as a meaningful relationship and shows the training that shapes Asuka's worldview. The chapter also foreshadows the core conflict of the mission—whether Asuka can trust and work with others when everything is at stake. Coach Li's warning that the mission isn't about individual feelings sets up the moral framework that will be tested throughout the story.

Study Questions and Answers

1. Why does Asuka's instinct to run to higher ground conflict with the simulation's actual goal?

Asuka's Japan training taught her to respond to an earthquake by getting away from the ocean immediately. This individual survival instinct saves her life in the sim, but the simulation was designed to test teamwork. By running alone, she leaves others behind, and Coach Li makes clear that the mission requires everyone to work together—individual survival isn't enough.

2. How does Gabriela's view of the mission differ from Asuka's, and what does this reveal about both characters?

Asuka sees the mission as an escape from a dying world, while Gabriela sees it as an act of hope—making more of the world rather than abandoning it. This reveals Asuka's despair and self-doubt, while Gabriela's optimism suggests she has a stronger belief in the mission's purpose and in humanity's worthiness of a second chance.

3. What does Coach Li's debrief reveal about the mission's values?

Coach Li's debrief makes clear that the mission prioritizes collective success over individual achievement. She emphasizes that the crew will have only each other, and that personal feelings or interpersonal conflicts must not jeopardize the mission. This sets up the novel's central question: can Asuka learn to trust and work with others?
