Chapter 7 — Leah: Summary and Analysis

⚠️ 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

Chapter 7, narrated by Leah, shifts the novel’s focus to the deep-sea expedition that will eventually strand the crew. The chapter opens with the submersible descending into the ocean. Jelka prays, as she habitually does, while Matteo silently checks and rechecks the oxygen systems, repeatedly announcing that the crew is fine and still breathing. Leah, for her part, holds her finger against the transmission button at ten-second intervals, registering a dead signal each time. She does not voice the thought that keeps occurring to her—that a submarine going down is not inherently a terrible thing, since this is exactly what they are supposed to be doing.

Leah reflects on the typical duration of a manned submersible’s descent to the deepest point in the ocean, estimating three to four hours depending on the craft’s size and engines. In a detached way, she wonders what would happen if they hit the bottom and could not control the ballast tanks to bring the craft back up. She also notes the oddity that the systems have cut out in all meaningful ways except for the CO2 scrubbers, which continue to function. A misplaced wish arises: she wishes she had brought a deck of cards, and she imagines the three of them sitting at the bottom of the ocean playing old maid.

The chapter closes with a description of the deep sea’s darkness, especially since the craft’s lights have cut out for unknown reasons. Leah deliberately keeps her gaze away from the windows, thinking instead of strange-shaped ocean creatures peering in at the three of them and smiling with all of their teeth.

Key Events

The submersible begins its descent, with Jelka praying and Matteo monitoring oxygen levels.
Leah repeatedly attempts to transmit a signal, but receives only dead responses.
Leah contemplates the descent time and the possibility of being unable to control the ballast tanks.
She observes that the CO2 scrubbers remain operational while other systems have failed.
Leah wishes for a deck of cards and imagines playing old maid at the ocean floor.
The craft’s lights cut out, leaving the crew in darkness, and Leah avoids looking out the windows.

Character Development

Leah emerges as a narrator who copes through dark humor and mental distraction. Her repeated thought that the descent is “just what we’re supposed to be doing” reveals a tension between rational acceptance and underlying anxiety. Her wish for a deck of cards and the image of playing old maid at the bottom of the ocean show a mind seeking normalcy and play in an extreme situation. Her decision to keep her gaze away from the windows suggests a deliberate avoidance of the unknown, a protective reflex against fear.

Jelka is shown through Leah’s observation to rely on prayer as a ritualized coping mechanism. The phrase “because that was what Jelka did” implies a pattern of behavior that Leah recognizes but does not share.

Matteo is portrayed as silent and methodical, focusing on the oxygen systems and repeatedly announcing that the crew is fine. His actions suggest a need for control and reassurance through technical checks, even as the broader situation deteriorates.

Themes, Symbols, or Motifs

Coping mechanisms: Each character responds differently to the descent—Jelka through prayer, Matteo through technical checks, Leah through dark humor and imagined games.
Isolation and communication failure: Leah’s repeated attempts to transmit a signal result in dead responses, emphasizing the crew’s disconnection from the surface and from any external help.
Mortality and helplessness: Leah’s speculation about being unable to control the ballast tanks points to the fragility of human life in an unforgiving environment.
Technology failure: The systems cutting out except for the CO2 scrubbers highlights the arbitrary nature of technological reliability and the thin margin between survival and disaster.
The unknown: The darkness outside the windows and the imagined creatures peering in symbolize the fear of what cannot be seen or understood.
Dark humor: Leah’s wish for a deck of cards and the image of playing old maid at the ocean floor serve as a coping mechanism that undercuts the gravity of the situation.
Survival instinct: Despite the failures, the CO2 scrubbers continue to work, and the crew remains alive, suggesting an underlying drive to persist.

Why This Chapter Matters

Chapter 7 establishes Leah’s perspective on the expedition and sets the psychological tone for the events that follow. It introduces the central tension of the novel—the descent into an environment where human control is limited and communication is severed. Leah’s internal monologue reveals her coping strategies and her awareness of the precariousness of their situation. The chapter also foreshadows the prolonged isolation and technological breakdown that will define the crew’s experience. By focusing on the mundane details of the descent—the oxygen checks, the transmission attempts, the wish for a deck of cards—the chapter grounds the extraordinary in the ordinary, making the impending crisis feel both intimate and inevitable.

Study Questions and Answers

1. How does Leah’s reaction to the descent differ from Jelka’s and Matteo’s?

Leah copes through dark humor and mental distraction, imagining a card game at the bottom of the ocean and repeatedly thinking that the descent is simply what they are supposed to be doing. Jelka relies on prayer as a habitual ritual, while Matteo focuses on technical checks and verbal reassurances about the oxygen systems. Each character’s response reflects a different way of managing fear and uncertainty.

2. What does the failure of the transmission signal suggest about the crew’s situation?

The dead signal indicates that the crew has lost contact with the surface, isolating them from any external support or communication. This failure underscores their vulnerability and sets the stage for the prolonged disconnection that will characterize their experience. It also highlights the theme of communication breakdown, both with the outside world and potentially among the crew themselves.

3. Why does Leah keep her gaze away from the windows, and what does this reveal about her state of mind?

Leah avoids looking out the windows because the darkness and the imagined creatures represent the unknown and the terrifying. By turning away, she is attempting to shield herself from the reality of their situation and from the fear of what might be outside. This action reveals her reliance on avoidance as a coping mechanism and her struggle to confront the vast, unknowable environment they are entering.
