Summary

The chapter opens with Chloe charging into the principal’s office to confess that she, not Georgia, was the student seen kissing a girl in the B Building bathroom. Principal Wheeler accepts the confession and bans Chloe from attending graduation, including any chance at giving a valedictorian speech. After a brief cry in the bathroom, Chloe meets Georgia outside. The two drive to Taco Bell and then to Belltower, the bookstore where Georgia works. In the loft, they have a long-overdue reconciliation: Chloe apologises for being a distant friend and for stealing the key to Shara’s house, and Georgia thanks Chloe for taking the fall. Georgia reveals she has been dating Summer Collins since the start of the note chase.

Summer arrives at Belltower, followed in quick succession by Benjy, Ash, Smith, and Rory. The group discusses Wheeler’s punishment and agrees that the school’s culture is toxic. Smith delivers a furious monologue about the pressure on students to be perfect. Summer suggests going public with their grievances. The idea of a protest graduation—held at the same time as the official ceremony at her father’s car dealership—takes shape. Smith begins recruiting others via phone. Students stream into Belltower: Ace, April, Jake, art club members, band kids, softball players, and even Student Body President Brooklyn Bennett, who insists on organizing the event. They paint banners, contact local news, and write demands, the first being “FIRE PRINCIPAL WHEELER.”

Amid the planning, Georgia presses Chloe about her feelings for Shara, but Chloe insists Shara is not a good person. Rory and Summer each defend Shara in part, revealing that Shara’s bad behaviour often had hidden motives. Chloe still refuses to believe Shara cares, noting that Shara did not show up to help. Later, Chloe retrieves her keys from the loft and accidentally overhears Smith and Rory below. Smith admits he never stopped thinking about Rory, and Rory confesses that all his new songs are about Smith. They share a kiss. Chloe smiles and hurries back to her friends, feeling that she has finally found where she belongs.

Character Development

Chloe Green—Chloe voluntarily sacrifices her graduation for Georgia, showing immense growth in loyalty and selflessness. She also acknowledges her own fault in neglecting their friendship. Her internal struggle with Shara continues, but she begins to prioritise the people who are present over the one who is not.

Georgia Neale—Georgia opens up about her relationship with Summer, revealing a hidden layer of her life. She also takes responsibility for not communicating earlier. Her role as a supportive friend and a budding activist solidifies.

Smith Parker—For the first time, Smith loses his composed exterior and speaks with raw anger about the school’s hypocrisy. His confession to Rory that he “never stopped thinking about you” shows his vulnerability and long-hidden feelings.

Rory—Rory admits to flooding the bio lab in protest of frog dissection—a prank motivated by protectiveness toward Smith. His line, “they’re all about you,” reveals the depth of his feelings and his willingness to be honest.

Summer Collins—Summer shares her own history with Shara, including a botched coming-out attempt, and proves her loyalty by helping organise the protest. Her presence grounds Georgia and connects the group further.

Principal Wheeler—Wheeler appears as a rigid, punitive figure who uses moral language to enforce control. He frames Chloe’s punishment as protecting the flock, exposing his prejudiced leadership.

Themes, Symbols, or Motifs

  • Sacrifice and solidarity—Chloe’s “gay grenade” metaphor underscores how one person’s risk can protect another and galvanise a community.
  • The power of community organising—The spontaneous gathering at Belltower shows how shared grievance can unite students across cliques. The banner and media strategy symbolise taking control of the narrative.
  • Hidden lives and shame—Ash’s MMORPG analogy explains that everyone is on a different quest; the “giant squirrels” represent invisible traumas. Chloe realises shame is institutionalised at Willowgrove.
  • Queer joy as resistance—The playful atmosphere, painting, ice cream, and flirtation among the protesters show that joy and rebellion can coexist.
  • Reclamation of space—The alternative graduation at a car dealership across from the school physically reclaims territory and visibility.
  • Religion and hypocrisy—Summer’s description of a different kind of Christianity challenges Chloe’s assumptions, and the group’s demands target the school’s discriminatory code of conduct.

Why This Chapter Matters

This chapter marks a turning point: Chloe’s sacrifice transforms personal guilt into collective action. The protest graduation subverts Wheeler’s punishment and gives the students agency. The reconciliations—Chloe and Georgia, Smith and Rory—restore relationships that had frayed under Willowgrove’s pressure. Chloe’s conclusion that she belongs with this makeshift family underscores her character arc from lonely outsider to invested community member. The chapter also sets up the final confrontation with the school administration and resolves the long-building tension between Smith and Rory.

Study Questions and Answers

1. Why does Chloe decide to confess to Wheeler, and what does this reveal about her character?
Chloe confesses because she knows that, unlike Georgia, she can handle the consequences. She also wants to protect Georgia, who is fragile and has more to lose. This act shows Chloe’s growth from a self-interested rule-breaker to someone who willingly sacrifices her own accolades for a friend.

2. How does Smith’s speech change the mood of the group, and what does it say about Willowgrove’s culture?
Smith’s outburst—rare for the usually unflappable quarterback—voices the pent-up frustration many students feel about having to be perfect. It validates the group’s anger and shifts the conversation from venting to action. His words highlight that Willowgrove demands a one-dimensional version of its students, leaving no room for their true selves.

3. What does Chloe learn about Shara from Rory and Summer, and does it change her mind?
Rory explains that Shara skipped Smith’s signing day to avoid ruining his photos; Summer reveals Shara fled a moving car when faced with a coming-out conversation. Chloe recognises Shara’s pattern of bailing before confronting her own queerness, but she still refuses to see Shara as a good person. The evidence complicates her view but does not yet sway her.
