⚠️ 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

In the Palm Springs rental, Poppy discovers Alex’s Tinder profile and immediately critiques his long, résumé-like bio and group photo. She insists he use a candid picture she took during their Tuscany trip—the moment he learned his story was accepted by Tin House. Poppy rewrites his bio with a humorous tone, emphasizing a bed frame and a dislike of the saxophone. As Alex swipes through profiles, Poppy becomes frustrated when he shows interest in a woman who reminds her of his ex-girlfriend Sarah. An argument erupts about “types”: Poppy accuses him of always pursuing safe, conventional women, while Alex counters that Poppy would never swipe right on someone like him. To prove him wrong, Poppy shows him her own Tinder profile—a Halloween photo and quirky bio. Alex looks at it, meets her eyes, and says, “I would.” The moment hangs heavy until Alex’s back spasms, breaking the tension. He reaches for the laptop and asks what she wants to watch.

Character Development

Poppy: Her playful critique reveals her deep knowledge of Alex’s habits and her protective feelings. When she reacts strongly to his type, she exposes jealousy she hasn’t acknowledged. Showing him her own profile is a dare that backfires, leaving her vulnerable.

Alex: He quietly accepts Poppy’s mockery, showing his trust in her. His defensiveness about the “Sarah” comparison hints at unresolved history. The moment he says “I would” is honest and direct—rare for him—and he immediately retreats into physical pain to reset the dynamic.

Themes, Symbols, or Motifs

The Tinder profile as a mask: Alex’s original bio is a carefully constructed self—competent, thorough, safe. Poppy’s rewrite strips away the pretense, replacing it with quirky authenticity. The argument over “types” shows how people reduce partners to archetypes, ignoring the messy reality of attraction.

The candid photograph: The Tuscany picture captures unguarded joy—the “naked Alex” Poppy loves. Choosing it for his profile is an intimate act, implying she wants the world to see the version of him only she knows.

The back spasm as escape: Physical discomfort interrupts emotional exposure. Alex’s back spasm functions as a safety valve, preventing the conversation from moving into overt romantic territory. Both characters use it to avoid a confession they aren’t ready to make.

Why This Chapter Matters

Chapter 18 is the emotional hinge of the present-day timeline. The Tinder debate forces Poppy and Alex to confront the gap between their friendship and the possibility of attraction. Alex’s “I would” is the closest either has come to admitting desire without the buffer of a joke or a trip. The chapter also grounds their history in a specific memory—the Tin House acceptance—linking Alex’s professional success to Poppy’s pivotal role in his life. It leaves the reader uncertain whether the next move will break the friendship or transform it.

Study Questions and Answers

Why does Poppy react so strongly to Alex swiping right on the graphic designer?
Poppy sees the designer as a stand-in for Sarah, Alex’s ex, whom she perceives as safe and conventional. Her reaction stems from jealousy and frustration that Alex keeps choosing women who fit a “boring” mold, implicitly excluding someone like Poppy who is loud, quirky, and unconventional.
What does the Tuscany photograph symbolize for their relationship?
The picture captures a private moment of pure joy—Alex’s literary success shared only with Poppy. By insisting he use that photo, Poppy claims an intimate vantage point. It represents the unfiltered version of Alex she treasures and wishes others could see, but it also shows how central she has been to his happiest moments.
How does Alex’s back spasm function in this scene?
The spasm serves as a physical interruption that defuses the romantic tension after Alex admits he would swipe right on Poppy. It allows both characters to retreat from the emotional precipice without having to address the implications of that admission, preserving the friend-zone equilibrium for now.
