Ella is paired with Brittany, the popular top student. Brittany immediately objects, claiming she needs to work with her carpool partner Crystal. Mrs. Bush allows the switch, reassigning Ella to Anton Peterson. Anton loudly refuses to work with Ella, insulting her by saying he can smell her and it makes him sick.

Character Development

- Anton – Shows casual cruelty and social dominance, comfortable humiliating Ella in front of the class. His refusal to work with her is both a personal insult and a reinforcement of school hierarchy.

Themes, Symbols, or Motifs
- Social hierarchy in school – The chapter illustrates how popularity determines treatment. Brittany can bend rules, Anton can bully, and Ella has no recourse.
- Isolation and marginalization – Ella’s exclusion from groups is a recurring motif; here she is doubly rejected, first by Brittany then by Anton.
- Teacher complicity – Mrs. Bush’s passivity in the face of overt bullying shows how authority figures can perpetuate student cruelty by not acting.
- Sight and smell – Anton’s insult about Ella’s smell connects to her home environment (the rotting peaches in the closet), linking her school shame to her home abuse.
Why This Chapter Matters
This chapter broadens the story beyond Ella’s home abuse, showing how her difficulties extend into every area of her life. It reinforces the theme of systemic neglect: adults at school, like those at home, fail to protect her. The visible public humiliation adds a layer of social trauma. Ella’s decision to work alone also foreshadows her self-reliance and the loneliness she endures. This chapter deepens empathy for Ella and builds tension as readers see the full scope of her challenges.
Study Questions and Answers
1. What does Anton’s insult reveal about Ella’s life outside school? Anton’s comment about Ella’s smell hints at the unsanitary conditions in her home—specifically the rotting fruit in the closet. It shows that her home abuse is not hidden; it affects her body and how others perceive her.
2. Why does Mrs. Bush not change the assignment after Anton’s refusal? Mrs. Bush likely prioritizes classroom order over fairness. Allowing Brittany’s excuse and ignoring Anton’s insult suggests that popular students face fewer consequences. Her inaction reflects a broader failure by adults to protect Ella.
3. How does Ella’s reaction to working alone show her character growth? Instead of begging or crying, Ella simply states she’s used to working alone. This indicates she has learned to expect rejection and rely on herself. Her resilience is born from repeated disappointment rather than strength, making it poignant.
