Summary

The chapter opens with Mia reflecting on the screams captured in the bird-watcher’s video. She argues that the screams might have nothing to do with her father’s disappearance, explaining that humans are evolutionarily wired to see causal connections—a cognitive bias that leads to false positives. She illustrates this with the hunter-gatherer example: assuming the rustling grass is a lion is safer than assuming it’s just wind. Mia suggests that the scream could be unrelated, perhaps the tail end of Eugene’s earlier meltdown, or a freak accident, or even a staged event for insurance purposes.

Shannon, the family’s lawyer, rejects these possibilities. She insists that the police, prosecutors, and judges share the same evolutionary programming and will not accept a story that doesn’t neatly explain all the evidence while exonerating Eugene. Shannon demands a plausible narrative that ties everything together. Mia is silent, unable to provide one.

Later, Mia fears that the case might remain an unsolved missing-person mystery. She reflects on how such cases are the ultimate puzzle—there is an answer, but only the missing person knows it. She contrasts this with fictional mysteries that always resolve, and she dreads the possibility that her father’s story will never be solved. Shannon, however, sees an unsolved case as the safest outcome for Eugene, unless they can craft a convincing exoneration story.

That night, the family works separately: Mom reviews Dad’s insurance policies and financial accounts, John goes through Anjeli’s therapy videos, and Mia and Vic retrieve Vic’s car from the park and work on cracking the password to Dad’s HQ files. They eventually succeed—the password is “Quotient,” a reference to Dad’s happiness quotient concept.

They gather in the family room to watch TV with Eugene, who falls asleep. John dims the lights, and they sit in silence. John recalls a childhood incident in Seoul where he pushed Mia, and she nearly stumbled into the path of a bike. He confesses that when he saw the video of Eugene, he thought of that moment—how quickly anger can turn into a snap decision with unintended consequences. He admits he wonders if Eugene pushed their father. Mia confesses she has had the same thought.

John then asks Mia, if she could choose, what would she hope happened to Dad? Mia initially resists, but then they begin to construct a story together, using their old logic-chain game. They imagine Dad and Eugene at the waterfall overlook, having lunch, watching birds. Teenage boys steal Dad’s wallet, and Eugene tries to catch the thrown backpack, backing toward the cliff. Dad grabs Eugene, but Eugene is panicking, and Dad screams for help. In the final moment, Dad uses his last strength to hurl Eugene to safety, but the force slides him off the edge. The story ends with Dad falling, but Eugene safe.

Vic wakes up and whispers that he had been thinking something similar—that Eugene was in danger and Dad fell trying to save him. He notes that this story explains all the evidence and exonerates Eugene, exactly as Shannon requested. Mia realizes that their constructed narrative is the story their lawyer asked them to brainstorm. She later regrets speaking it aloud, wishing they had kept it in their minds, because the spoken words made it feel real and set off a chain of doubts.

Character Development

Mia: She grapples with her own cognitive biases, oscillating between wanting to believe the scream is unrelated and fearing the worst. Her regret at the end shows her growing awareness of how narratives can shape reality and her own emotional state.
John: He reveals a vulnerable side, admitting his childhood guilt and his fear that Eugene might have acted impulsively. His willingness to engage in the logic-chain game shows his need for comfort and resolution.
Eugene: Though asleep for most of the chapter, his presence is central. The family’s protective instincts and the constructed story revolve around his safety and innocence.
Vic: He demonstrates his loyalty and insight, having independently arrived at the same exoneration narrative. His reminder that this story fulfills Shannon’s request highlights his practical thinking.
Shannon: Though not physically present in the later scenes, her demand for a plausible story drives the family’s brainstorming. Her legal pragmatism contrasts with Mia’s philosophical musings.

Themes, Symbols, or Motifs

Causation Bias and Narrative Construction: The chapter explores how humans instinctively create causal connections and stories to make sense of events. Mia’s explanation of false positives and the family’s construction of a heroic narrative both illustrate this theme.
Ambiguity vs. Resolution: Mia’s fear of an unsolved mystery and her desire for a definitive answer highlight the tension between living with uncertainty and needing closure.
The Waterfall as Symbol: The waterfall overlook becomes the setting for the imagined heroic rescue, representing both danger and the possibility of redemption. The “veil” of the waterfall suggests obscured truth and the family’s attempt to see through it.
The Logic-Chain Game: This childhood game becomes a tool for the siblings to collaboratively build a comforting story, showing how shared imagination can provide solace.
Hope vs. Realism: Shannon’s insistence on realism clashes with Mia’s hope for a benign explanation. The constructed story is a compromise—realistic enough to be plausible, but hopeful enough to exonerate Eugene.

Why This Chapter Matters

This chapter deepens the central mystery by introducing the possibility that the screams are unrelated to Dad’s disappearance, while also showing how the family’s need for resolution leads them to construct a narrative that may or may not be true. It reveals the psychological mechanisms behind their storytelling and sets up a potential exoneration theory that could become pivotal in the legal case. The chapter also humanizes John and Mia, exposing their shared fear and their desire to protect Eugene. The regret Mia feels at the end foreshadows that this constructed story may have unintended consequences, adding tension to the unfolding plot.

Study Questions and Answers

1. Why does Mia argue that the screams in the video might be unrelated to Dad’s disappearance?

Mia explains that humans have a cognitive bias toward seeing causal connections, even when none exist. She uses the example of hunter-gatherers assuming rustling grass is a lion—a false positive that was evolutionarily advantageous. She suggests that the scream could be the tail end of Eugene’s earlier meltdown, or a freak accident, or even a staged event, and that in real life, coincidences happen.

2. What story do John and Mia construct, and why does it satisfy Shannon’s requirements?

They imagine that teenage boys steal Dad’s wallet, Eugene tries to catch the thrown backpack and backs toward the cliff, Dad grabs him, and in the struggle, Dad hurls Eugene to safety but falls himself. This story explains the wallet’s absence, the screams, and the fall, while exonerating Eugene. It ties up all evidence neatly and presents Dad as a heroic, self-sacrificing father.

3. Why does Mia regret speaking the story aloud?

Mia feels that by verbalizing the narrative, they made it feel real and concrete, which could lead to false hope or later disappointment. She also worries that the story might be a form of self-deception, and that once spoken, it cannot be taken back. The regret suggests she is aware of the power of narrative to shape perception and emotion.
