⚠️ 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

Chapter 10, “big sister says,” opens with the big sister’s voice offering a gentle correction to the reader’s sense of isolation. The reader is told they are less alone than they realize, and the key to finding connection is to open the heart as wide as a butterfly net—suggesting an active, receptive posture rather than a passive wait. The advice emphasizes patience and vigilance as twin disciplines for finding one’s people.

The chapter then shifts to a brief exchange. Friends invite the protagonist to a party, and she declines, saying she would rather stay home and get lost in a book. The narration immediately identifies this refusal as running away out of fear, framing the bookish retreat not as a simple preference but as an avoidance pattern.

The big sister’s voice returns to address this contradiction directly. The reader wants others to prove they care, yet continues to push everyone away. The sister asks why, then offers a prescription: open every window, let love inside, and stop letting what-ifs limit you. The imagery of windows suggests that the barriers keeping love out are not walls but openings that have been sealed shut—and that the reader has the power to unseal them.

The chapter closes with a stark scene that contrasts sharply with the sister’s hopeful counsel. The protagonist is kneeling in front of a toilet, searching for release. The narration states that there is nothing in this life she feels she has control over—except this act, which she will not let anyone take from her. The final detail is scabs on her knuckles, a physical trace of self-harm.

Character Development

The protagonist’s defining trait in this chapter is the gap between her desires and her actions. She wants connection—the big sister’s advice assumes this desire—yet she actively declines opportunities for it. The party invitation is a concrete instance of community reaching out, and her refusal reveals a pattern of self-sabotage. The narration’s explicit labeling of her behavior as “running away scared” removes ambiguity: this is not a neutral choice but a fear-driven retreat.

The closing scene deepens our understanding of the protagonist’s inner life. Her relationship with control is inverted: she feels powerless over the broad circumstances of her life, so she seizes control over the one domain she can—her body, through disordered eating and self-harm. The scabs on her knuckles are a physical manifestation of this struggle, a visible trace of invisible pain.

The big sister functions as a counter-voice, offering the perspective the protagonist cannot yet access. She names the contradiction (wanting care while pushing away), asks a pointed question (why?), and offers a path forward (open the windows). Her role is not to solve the problem but to hold up a mirror.

Themes, Symbols, or Motifs

The butterfly net is the chapter’s central metaphor for receptivity. A net is not a passive container; it requires active sweeping, patience, and vigilance. The image suggests that finding one’s people is not a matter of luck but of practiced openness.

Windows function as a motif for vulnerability. The sister’s instruction to “open every window” implies that the reader has sealed herself off from love, and that the barriers are permeable—they can be opened from within. The contrast with the toilet scene is stark: the toilet is a private, closed space of bodily control, while windows are public, open spaces of connection.

What-ifs represent the limiting beliefs that keep the protagonist trapped. The sister’s call to stop letting what-ifs limit her suggests that hypothetical fears—what if they reject me, what if I’m hurt again—are the real walls keeping love out.

The toilet and scabs form a motif of bodily control and self-harm. The toilet scene reveals the protagonist’s belief that this act is the only thing she can control, and the scabs on her knuckles suggest a history of self-inflicted harm. These images ground the chapter’s more abstract advice in physical reality.

Why This Chapter Matters

This chapter is pivotal because it juxtaposes the big sister’s hopeful counsel with the stark reality of the protagonist’s coping mechanisms. The advice—open your heart, let love in, stop limiting yourself—is sound, but the closing scene reveals how far the protagonist is from being able to follow it. The chapter does not offer a resolution; it offers a diagnosis.

The chapter also matters for its unflinching portrayal of disordered eating and self-harm. These are not sensationalized but presented as the protagonist’s attempt to reclaim agency in a life where she feels she has none. The detail of the scabs on her knuckles is a quiet, devastating image that lingers.

Finally, the chapter establishes the big sister as a recurring voice of guidance. Her role is not to fix the protagonist but to name the truth and offer a direction. The gap between her advice and the protagonist’s reality is the space where the rest of the book will operate.

Study Questions and Answers

1. How does the butterfly net metaphor shape the big sister’s advice about finding community?

The butterfly net metaphor reframes the search for community as an active practice rather than a passive hope. A net must be held open, swept through the air, and kept ready—this requires patience and vigilance, exactly the qualities the sister names. The image also suggests that connection is something one catches, not something one waits for. The reader is told to open their heart “as wide as a butterfly net,” implying that the heart’s openness is the precondition for finding one’s people.

2. What does the contrast between the party invitation and the toilet scene reveal about the protagonist’s internal conflict?

The party invitation represents an external offer of connection—friends actively trying to include her—while the toilet scene represents an internal, private struggle for control. The contrast reveals that the protagonist’s isolation is not a lack of opportunity but a fear-driven choice. She declines the party because she is “running away scared,” yet she seeks control in the most private, bodily way possible. The chapter suggests that her need for control over her body is a response to feeling powerless over her social and emotional life.

3. How do the motifs of windows and what-ifs work together to explain the protagonist’s self-sabotage?

Windows represent the openings through which love could enter, and what-ifs represent the fears that keep those windows sealed. The sister’s instruction to “open every window” implies that the protagonist has the agency to unseal them, but the what-ifs—hypothetical fears about rejection, hurt, or failure—are what keep them shut. The chapter suggests that self-sabotage is not a lack of desire for connection but a fear of what connection might cost. The what-ifs are the internal voice that justifies keeping the windows closed.
