Summary

Eight months before launch, Asuka sits with the crew in the Dining Mod during one of Coach Li's worst-case-scenario simulations. Her nerves are frayed from a tense phone call with her mother the night before. Her mother had tried to make peace by sharing details of a conservation project, but then called the mission's people “evil.” Asuka, heartbroken, ended the call.

The simulation begins with a fire erupting in the adjacent Kitchen Mod. Asuka, closest to the kitchen, runs in and finds three crew members knocked unconscious by a mini explosion. She tries to activate the sprinklers, but one is blocked by crates and the other is off. As smoke and flames fill the space, Ying Yue and others haul two crew members out, but a third is trapped under a fallen shelving unit. Asuka freezes, overwhelmed by a traumatic memory of a pool of ash and her mother's arms. Ying Yue shouts her name, snapping her back.

Asuka climbs onto a stool and repeatedly bashes a sprinkler head with a metal pot insert until it breaks, releasing a gush of water. Ying Yue grabs her and pulls her out, and they seal the Kitchen Mod. The fire spreads through the air ducts to the Agriculture Module. Asuka runs to the control panel and shuts down inter-mod airflow to prevent further spread. The full extinguishing protocol takes five minutes, causing extensive damage to the habitat wheel—including the Kitchen, Dining Mod, two Ag Mods, and one Crew Quarters.

Afterward, at lunch, they learn that Becky's group finished the same scenario in a tenth of the time. Becky sealed and vented the Kitchen in the first three minutes, earning top marks. When Ying Yue asks what happened to the crew inside, the answer is that they died. Asuka watches Becky laughing with other officers, and Becky catches her eye with a look that seems to say “So what?” Asuka takes a bite of curry without tasting it, wondering which choice she would make if forced to choose between the mission and the crew.

Themes, Symbols, or Motifs

Mission vs. crew sacrifice: The central dilemma of the chapter. Becky's group chooses the mission; Asuka's group tries to save everyone, but at the cost of time and damage.
Trauma and memory: Asuka's flashback to a pool of ash and her mother's arms shows how past trauma can resurface under pressure, affecting decision-making.
Blank slate symbolism: The white interior of the Phoenix is described as a deliberate blank slate, but Asuka's mind is anything but blank—it is filled with memories and doubts.
Teamwork vs. individual heroism: Asuka's attempt to break the sprinkler is a solo act, while Ying Yue coordinates the group. The chapter contrasts these approaches.
Moral dilemma: The simulation forces characters to confront whether the mission's success justifies sacrificing lives.

Why This Chapter Matters

This chapter establishes Asuka's central internal conflict and sets up a key contrast with Becky that will likely shape later events. It also reveals Asuka's traumatic past and her strained relationship with her mother, providing emotional depth. The simulation's outcome—Becky's ruthless efficiency versus Asuka's slower, more humane approach—foreshadows the ethical choices Asuka will face during the actual mission. The chapter also introduces the theme of sacrifice, which is central to the novel's plot.

Study Questions and Answers

1. Why does Asuka hesitate during the fire simulation, and what does this reveal about her character?

Asuka hesitates because she is overwhelmed by a traumatic memory of a fire and her mother's embrace. This reveals that her past experiences deeply affect her ability to act under pressure, and it shows her vulnerability. It also suggests that her desire to save everyone may be rooted in a personal need to prevent loss.

2. How does Becky's approach to the simulation differ from Asuka's, and what does this contrast suggest about their values?

Becky seals and vents the Kitchen immediately, sacrificing the crew inside to contain the fire quickly. Asuka tries to save the crew and break the sprinkler, but her group takes longer and causes more damage. This contrast suggests Becky prioritizes the mission's success above individual lives, while Asuka values human life over efficiency. It sets up a moral divide that may become critical later.

3. What does Asuka's final question—wondering which choice she would make—indicate about her state of mind?

Asuka's uncertainty shows that she is not fully committed to either approach. She is torn between her instinct to save people and the mission's demands. This internal conflict suggests she will face a difficult decision in the future, and her answer may define her character arc.
