Summary

The chapter opens with Courtney urgently asking Amy to meet at Sarabeth's Kitchen, a Manhattan café known for its scones and status-conscious clientele. Amy assumes Courtney has received a job offer, but instead Courtney tearfully confesses that she and Marc are in love and have been together since before Amy and Marc separated. Courtney changes the timeline three times, finally admitting they got together “right before you guys ended it for good.” Amy is devastated, especially when she realizes Courtney told Marc about Josh. Feeling betrayed by her best friend and her ex-husband, Amy leaves the café, her legs buckling as she recalls her sister Ollie teaching her to skate as a child—an “inchworm” memory that underscores how betrayal has been a recurring pattern in her life.

For six months, Amy avoids Courtney, not returning calls or acknowledging her at work. During this time, she attends a psychology conference in Seattle, where she meets TJ, a charismatic researcher presenting the “Empathy Project.” His talk draws huge crowds, and Amy, as a book editor, approaches him about turning his research into a popular book. They have dinner, and TJ confesses he participated in his own study as a “decoy” dressed as a homeless person—a clear ethical violation. Despite Amy's misgivings, she is drawn to him. They collaborate on his book, which becomes a bestseller, and they begin an affair, even though TJ is married with a young daughter, Daisy.

Amy rationalizes the affair, telling herself she is special to TJ. But TJ's wife, Alice, calls Amy to warn her that she is not the only one and that TJ is using her. Amy continues the affair anyway, meeting TJ at conferences and playing at being a couple. She eventually discovers TJ sleeping with other women, including a bookstore clerk and his publicist. She berates herself for being stupid, skips therapy sessions, and punishes herself. When she does see her therapist, Paul, she is surly and resistant, but he gently encourages her to consider medication and more frequent sessions. Amy agrees to see him twice a week and also joins the Y, taking up swimming as a way to cope. She tells herself, “sink or swim, Shred.”

After six months of avoidance, Amy spots Courtney in the company cafeteria and impulsively joins her. They slip back into their old friendship, and Courtney reveals she and Marc are getting married at City Hall. Amy agrees to meet Marc at Bethesda Fountain in Central Park. There, she confronts him about sleeping with Courtney while they were still married. Marc initially deflects, but eventually admits, “We fooled around, okay?” Amy feels vindicated, though the conversation ends bitterly.

Meanwhile, TJ's research methods are exposed by a graduate student, leading to a symposium that discredits his study. His academic reputation is tarnished, but his book remains a bestseller. He invites Amy to a conference in the Florida Keys, but she declines, signaling a break from her self-destructive pattern.

Character Development

Amy undergoes significant growth in this chapter. Initially, she is a victim of betrayal, but she also becomes a participant in her own self-destruction through the affair with TJ. Her realization that she is “punishing herself” and her decision to resume therapy and take up swimming mark a turning point. By the end, she is able to decline TJ's invitation, showing a new capacity for self-respect.

Courtney is portrayed as remorseful but also calculating. She changes her story multiple times, and her desperation for Amy's forgiveness suggests guilt, but her decision to marry Marc shows she prioritizes her own happiness.

TJ emerges as a charismatic but unethical figure. His willingness to compromise his research and his pattern of infidelity reveal a man who uses others for his own gain. His downfall is academic, but his commercial success persists, highlighting the gap between public acclaim and personal integrity.

Marc admits his infidelity but remains defensive, deflecting blame onto Amy's past with Josh. His admission is a moment of truth, but it does not lead to reconciliation.

Themes, Symbols, or Motifs

Betrayal and Self-Deception: The chapter explores multiple layers of betrayal—Courtney's friendship betrayal, Marc's marital infidelity, and TJ's professional and personal dishonesty. Amy's own self-deception is central; she rationalizes the affair despite knowing it is wrong.
Empathy: The Empathy Project, which measures drivers' reactions to homeless decoys, serves as a metaphor for the lack of empathy in Amy's personal relationships. TJ's unethical methods undermine the very concept he studies.
Sink or Swim: Amy's mantra while swimming reflects her determination to survive emotional turmoil. The pool becomes a place of healing and community.
Inchworm Memory: The childhood memory of Ollie teaching Amy to skate symbolizes the pattern of betrayal that began with her sister. It recurs as Amy processes Courtney's confession.
Status Symbols: The café's clientele and Courtney's aspirations to a life of leisure highlight themes of class and ambition, contrasting with Amy's more grounded values.
The Blue Pencil: Amy's editing tool represents her professional identity and her ability to shape narratives, but also her complicity in polishing TJ's flawed work.

Why This Chapter Matters

This chapter is a pivotal turning point in Amy's journey. It brings together the two major betrayals of her life—her best friend and her husband—and forces her to confront her own role in her suffering. By ending the affair with TJ and declining his invitation, Amy demonstrates growth and self-awareness. The chapter also deepens the novel's exploration of family dysfunction, as Amy's reaction to Courtney echoes her history with Ollie. It sets the stage for Amy's continued healing and her redefinition of self-worth.

Study Questions and Answers

1. How does Amy's reaction to Courtney's betrayal echo her relationship with her sister Ollie?

Amy's immediate physical collapse and the flashback to Ollie teaching her to skate suggest that Courtney's betrayal triggers the same feelings of helplessness and abandonment she experienced with Ollie. The “inchworm” memory—where Ollie guided her but also raced ahead—mirrors Courtney's mentorship and subsequent betrayal. Amy even notes that Ollie was her “first and best teacher in the art of betrayal,” indicating that this pattern is deeply ingrained.

2. What role does the Empathy Project play in the chapter's themes?

The Empathy Project is a study designed to measure compassion, but TJ's unethical participation as a decoy undermines its integrity. This irony highlights the gap between public performance and genuine empathy. Amy's involvement in promoting the book, despite knowing about the ethical violation, reflects her own self-deception. The project's eventual discrediting parallels Amy's growing awareness of her own rationalizations.

3. Why does Amy decline TJ's invitation to the conference in the Keys?

Amy's refusal marks a significant shift in her character. Earlier, she would have rationalized the trip as a professional opportunity, but now she recognizes that TJ is a destructive influence. Her loneliness and temptation are real, but her decision to decline shows that she is no longer willing to sacrifice her self-respect for a hollow relationship. It signals her commitment to healing and her rejection of the self-punishing patterns that defined her affair.
