Key Events
- Abby leads the ride and handles Sebastian’s earlier incident calmly, but Sebastian avoids her afterward.
- Lizzie sends Abby a TikTok video exposing Sebastian’s pattern of dating multiple women in the same social circle.

Character Development
Abby grows as a ride leader by maintaining professionalism even as her personal feelings get complicated. She also grapples with self-worth: initially feeling “basic” and “not special” after learning about Sebastian’s past, she eventually asserts her own boundaries. Her conversation with Lizzie shows her vulnerability and her attempt to compartmentalize.
Sebastian is revealed to have a history of casual relationships that are now publicly exposed. His misery at dinner and his earnest appeal to Abby suggest a desire for genuine connection, though his actions contradict his words. He admits he was looking for Abby after their night together, indicating his feelings may have been deeper than his reputation suggests.
Lizzie acts as a support system, sending the TikTok as a peace offering and validating Abby’s hurt. Eileen appears at dinner with her usual nosiness, but Abby acknowledges her mother’s clumsy efforts to reconnect.
Themes, Symbols, or Motifs
- Online shaming and mob justice – The TikTok video and subsequent media coverage turn Sebastian into a public spectacle, raising questions about judgment and privacy.
- Double standards vs. accountability – Abby reflects on how men move through the world heedlessly, and women (like the TikTok’s creator) are mocked for calling out behavior. The chapter shows both sides of the controversy.
- Body image and self-perception – Abby’s humorous aside about being the “bigger person” echoes her internal battle with her weight and her mother’s scrutiny.
- Unfulfilled potential – The motif of “alternate timelines” appears when Sebastian imagines a life where they are together in Tuscany, contrasting with Abby’s current reality with Mark.
Why This Chapter Matters
Chapter 15 is a turning point in the narrative because it reveals the central secret about Sebastian that has been hinted at since his introduction. It forces Abby to reconcile the sweet, attentive man she met two years ago with the internet’s portrayal of a serial dater. The public exposure of the scandal also tests Abby’s leadership and her relationship with Mark. The chapter deepens the romantic tension and sets up future conflicts, both for Abby and Sebastian and for Abby’s evolving bond with her mother.
