⚠️ 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 {#summary}

Chapter 20, titled Scene: Bathtub Conversation, is written in script format, with the action described in stage directions and the dialogue presented as a two-person exchange between Wren and Lewis. The scene opens with Lewis seated in a wheelchair outside the bathroom while Wren prepares his bath. She pours a bag of salt into the tub's water, then moves his nightstand next to the bathtub so that it is within his reach. She helps Lewis into the tub, and a bit of water overflows onto the floor as he settles in. Finally, she positions his head on an inflatable pool toy that serves as a pillow.

Once Lewis is comfortable, Wren offers him his book, noting that he always reads before bed. Lewis declines, saying he does not feel like reading. Wren presses him, asking if he is sure, and he confirms that he is. She then suggests that an airplane pillow might be more comfortable than the pool toy, but Lewis insists he is fine.

Wren tells Lewis that he is yelling at her. Lewis denies this, saying he is not yelling, and adds that if she were not hovering over him all the time, it would not seem so loud. Wren asks what has happened to him, and Lewis replies that they both know what happened. The conversation ends with Wren asking whether Lewis minds if she watches Game of Thrones without him this time. Lewis tells her she can do whatever she likes.

The chapter is brief and entirely contained within this single scene, with no narration outside the stage directions and dialogue.

Character Development {#character-development}

Lewis is shown in a state of pronounced physical and emotional decline. The wheelchair, the need for help entering the tub, and the salt bath all point to a body that is no longer his own. His refusal to read, his curt dismissal of Wren's suggestions, and his accusation that she is hovering reveal a man who is irritable, withdrawn, and struggling to accept his dependence. His line that they both know what happened to him is the chapter's clearest acknowledgment that the shark transformation is the cause of his condition, even if he cannot or will not discuss it directly.

Wren is depicted as a devoted but increasingly strained caregiver. She anticipates Lewis's needs—preparing the salt bath, moving the nightstand, offering the book, suggesting a more comfortable pillow—yet her efforts are met with resistance. Her question about what has happened to him and her request about Game of Thrones show her trying to maintain a connection that Lewis is actively pushing away. Her hovering, which Lewis criticizes, reads less as overbearing and more as a desperate attempt to hold on to the person he used to be.

Themes, Symbols, or Motifs {#themes-symbols-or-motifs}

Caregiving and dependency are the chapter's central concern. Every action Wren takes—pouring salt, moving furniture, helping Lewis into the tub—is an act of care that simultaneously reinforces Lewis's dependence. The wheelchair and the overflowing water are small but vivid markers of how much his body has changed.

Loss of independence is closely tied to this. Lewis's refusal of the book and his insistence that he is fine are attempts to assert control over a situation in which he has very little. His irritation at Wren's hovering is, at its core, a protest against being treated as someone who needs help.

Saltwater as symbol connects directly to the shark transformation. The salt bath is a practical measure—saltwater is associated with the sea and with sharks—but it also serves as a reminder of what Lewis is becoming. The water that overflows the tub hints at a force that cannot be contained.

Withdrawal from shared rituals is evident in Lewis's refusal to read and his indifference to Game of Thrones. These are activities the couple once did together, and his rejection of them signals an erosion of intimacy.

Irritability toward care and the erosion of intimacy are intertwined throughout the dialogue. Lewis's comment about Wren hovering is the sharpest moment in the chapter, revealing how caregiving can create distance even as it is meant to bring people closer.

Why This Chapter Matters {#why-this-chapter-matters}

Chapter 20 is a quiet but pivotal scene that crystallizes the emotional state of the couple at this point in the novel. The script format sets it apart from surrounding chapters, giving the conversation a theatrical intimacy that makes the distance between Wren and Lewis feel all the more stark. The chapter does not advance the plot in a dramatic way, but it deepens the reader's understanding of how the shark transformation is affecting both characters.

The scene also establishes the practical realities of Lewis's decline—the wheelchair, the salt bath, the need for help with basic tasks—while showing how those realities are straining the marriage. Lewis's refusal to engage with Wren's attempts at connection, and his pointed comment about her hovering, mark a turning point in their relationship. The chapter matters because it shows that the transformation is not just physical but relational, and that the couple is beginning to lose each other even as they remain in the same room.

Study Questions and Answers {#study-questions-and-answers}

1. What does Lewis's refusal to read and his indifference to Game of Thrones reveal about his state of mind?

Lewis's refusal to read and his indifference to Game of Thrones show that he is withdrawing from the shared rituals that once defined his relationship with Wren. Reading before bed is something Wren explicitly says he always does, so his refusal is a clear break from his own habits. His comment that she can do whatever she likes about the show is similarly dismissive, suggesting that he no longer cares about maintaining the connection these activities provided. This withdrawal points to a deeper emotional retreat, one that mirrors his physical decline.

2. How does the salt bath function as a symbol in this chapter?

The salt bath functions as a symbol of Lewis's transformation. Saltwater is associated with the sea and with sharks, so the bath is a practical nod to the creature Lewis is becoming. At the same time, the overflowing water suggests something that cannot be fully contained, hinting at the uncontrollable nature of his change. The salt bath is also an act of care by Wren, but it is care that is tied to the very thing that is taking Lewis away from her.

3. What does Lewis mean when he says that if Wren were not hovering, it would not seem so loud?

Lewis's comment about Wren hovering is a deflection of her accusation that he is yelling. By blaming her proximity for making his voice seem loud, he avoids addressing the real issue—his own irritability and withdrawal. The comment also reveals a growing resentment toward Wren's caregiving. Her hovering, which she likely intends as attentiveness, feels to him like surveillance or pressure. The line captures the central tension of the chapter: caregiving is meant to bring them together, but it is instead driving them apart.
