Summary

The chapter opens with Aiko alone at a Nevada bus depot, holding $3.78 in scavenged money. She scans the floor for more coins, finding a nickel among the litter, but her search is interrupted when she nearly collides with a police officer who questions why a child is traveling alone. Aiko lies, claiming her mother is nearby collecting luggage. She recalls her father's advice that police can be trusted, but her instincts tell her otherwise, and she thinks of the shinigami—a demon of death that can take human form and corrupt through questioning.

The officer presses her and places a hand on her shoulder, preparing to escort her to find her mother. Before she must decide whether to run or confess, a large red fox bursts into the terminal. The animal weaves between the officer's legs, forcing him to hop and shout, and Aiko seizes the moment to sprint into the crowd. She follows a couple boarding a bus, then veers off into a dark luggage-storage area, where she climbs onto a shelf and hides behind boxes.

While hiding, Aiko finds a long white envelope containing a bus ticket to Yakima, Washington, and forty dollars in ten-dollar bills. She feels guilty keeping it—it feels like stealing—but reasons that with no name on the ticket, she cannot return it. She prays for forgiveness, wondering if the shinigami's touch has made her more demon-like.

An elderly man approaches her and asks if she is taking the Yakima bus. He introduces himself as Thomas Chun, a Chinese-American man returning home to his daughter's family in Yakima. He offers to sit with her, and when Aiko hesitates to give her name—fearing it would reveal she is Japanese—he proposes they pretend she is his granddaughter, Emily, traveling with him from Salt Lake City. She accepts, relieved.

On the bus, Thomas tells Aiko about his years working at the Boeing plant in Seattle, building bombers for the military. Aiko mentions her father is a pilot returning from the Pacific, and she proudly tells Thomas about her grandfather, Wasaburo Oishi, a Japanese scientist who discovered high-altitude air currents. Thomas warns her to be careful about revealing her Japanese heritage, and they agree to keep quiet. He gives her caramels.

As night falls, Aiko notices Thomas is cold—his lips and fingertips turning blue. She gives him her scarf, insisting she is dressed warmly enough. He accepts gratefully.

When the bus stops in Klamath Falls, Oregon, Aiko wakes eager to tell Thomas about her plan to find her father in Bly. But she finds him dead, his head tilted unnaturally, his expression blank. Small white spiders crawl over him—spiders emerging from the folds of her scarf. Aiko realizes she brought them aboard, likely picking them up in the field outside the Salt Lake City train station, and that giving the scarf to Thomas killed him. She wonders whether the spiders are magical creatures sent by Japanese gods or apparitions like the spirits she encountered at Minidoka. Terrified of being detained and missing her father, she carefully lifts the scarf from Thomas's neck, tiptoes off the bus, and heads alone into the dark woods.

Character Development

Aiko continues to evolve from a frightened child into a survivor who must make impossible choices. She lies to the police officer despite her father's teaching, steals a ticket and money out of desperation, and accepts a false identity to protect herself. Her guilt over Thomas's death—knowing she gave him the scarf that carried the spiders—deepens her sense of responsibility and her fear that she is becoming something monstrous. Her decision to flee rather than report the death shows how the threat of detention outweighs her moral instincts.

Thomas Chun is a brief but significant presence. His kindness—offering caramels, proposing the granddaughter cover story, and warning her about revealing her heritage—provides Aiko with a rare moment of safety and human connection. His death underscores the chapter's central horror: that Aiko herself is now a carrier of the deadly threat.

The fox functions as a guardian figure. Aiko believes it may be the same fox that led her through the desert, and she suspects it is her mother watching over her—a belief that carries the painful implication that her mother may be dead.

Themes, Symbols, or Motifs

The kitsune fox spirit appears as a protector, intervening at a moment of crisis. Aiko's conviction that the fox is her mother's spirit ties the supernatural to maternal love and sacrifice.

The shinigami recurs as a symbol of corruption and moral erosion. Aiko worries that the demon's touch has made her more capable of lying and stealing, blurring the line between survival and moral compromise.

Spiders as death omens connect this chapter to earlier scenes. The small white spiders that emerge from Aiko's scarf—spiders she unknowingly carried—transform her from victim to unwitting agent of death, a devastating twist on the theme of contamination.

Identity concealment is central. Aiko must hide her Japanese name and heritage to avoid detention, and Thomas's offer to make her Emily is both a kindness and a reminder of the prejudice that forces her to erase herself.

Guilt and responsibility drive the chapter's emotional climax. Aiko's realization that she killed Thomas through her gift of the scarf forces her to confront the possibility that she is dangerous to those who help her.

Why This Chapter Matters

This chapter marks a turning point in Aiko's journey. It establishes her as an unwitting carrier of the supernatural threat, a development with major implications for the rest of the novel. The death of Thomas Chun—a kind, innocent man—demonstrates the cost of Aiko's survival and deepens the novel's exploration of how war and prejudice spread harm. The chapter also solidifies the kitsune as a protective presence while raising the question of whether the spiders are supernatural or psychological apparitions, keeping the novel's ambiguity intact. Finally, Aiko's decision to flee rather than report Thomas's death shows how the fear of detention has corrupted her trust in authority, a theme that resonates with the novel's historical setting.

Study Questions and Answers

1. Why does Aiko lie to the police officer, despite her father's advice that police can be trusted?

Aiko's father told her she could always go to a policeman if she were in trouble, but her instincts override that teaching. As a Japanese-American child traveling alone during wartime, she knows that revealing her identity could lead to detention. Her fear of authority is justified by the historical context of Japanese internment, and the chapter shows how that fear has made her unable to trust the very institutions her father believed in.

2. What does the fox represent in this chapter, and what does Aiko's interpretation of it reveal about her emotional state?

The fox acts as a guardian, intervening to save Aiko from the police officer. Aiko believes it is the same fox that led her through the desert and suspects it is her mother's spirit watching over her. This interpretation reveals both her desperate need for maternal protection and her unspoken fear that her mother is dead—a fear she cannot fully accept.

3. How does Aiko's discovery of the spiders change her understanding of herself?

Aiko realizes she unknowingly carried the spiders from the field outside the Salt Lake City train station and that giving the scarf to Thomas Chun killed him. This transforms her from a victim of circumstance into an unwitting agent of death. She begins to question whether she is becoming demon-like herself, and the guilt she feels deepens her isolation, as she cannot report the death without risking detention.
