Summary

The afternoon before Sue's second portrait attempt, Sadie takes Peanut on his first long walk since his illness. She uses the time to plan new painting techniques, having researched the brain, neuroplasticity, and creative strategies. She's developed three ideas to bypass her fusiform face gyrus: having Sue describe her face in words to create a new neural path, turning the face upside down or sideways so her brain doesn't recognize it as a face, and using a mathematical grid approach inspired by artist Chuck Close. She's prepared a canvas, measuring tape, and a projector with a grid.

A sudden downpour forces Sadie and Peanut to race home through heavy rain. In the elevator, they encounter Joe and a woman Sadie recognizes by her Poison perfume as Parker. Joe tries to give Sadie his jacket, struggling with a stuck zipper before pulling it off over his head. Sadie wraps it around Peanut instead. Parker, seeing Joe's attention on Sadie, fakes dizziness and faints into his arms. He carries her to her apartment, where she gives him her passcode.

Sadie finds her own door lock broken—the dead bolt stuck in the latch position. She texts Mr. Kim three times with no response and waits in the hallway, shivering with Peanut. When Joe emerges from Parker's apartment, he brings Sadie to his own place.

Joe's apartment is penthouse-fancy but completely empty—no furniture except barstools and a mattress on the floor. He lets Sadie shower, blow-dries Peanut, leaves clothes for her, and orders Italian takeout. Over linguine fra diavolo, Joe reveals his wife cheated on him with a coworker, he found them together in a hotel hot tub, and he beat up the man. He gave all his furniture to Goodwill and has lived in the empty apartment for a year.

Sadie then tells Joe about Parker. She explains that after her mother died, her father remarried quickly, and Parker moved in, framed Sadie for vicious bullying that Parker herself was committing against a girl named Augusta Ross, and got Sadie expelled from school and kicked out of the house. Parker had typed threatening anonymous notes in a hidden file on Sadie's laptop and handed it to administrators. Augusta had attempted suicide with Tylenol before the truth came out. Sadie's father sided with Parker, calling the evidence incontrovertible. Parker stole Sadie's room, clothes, friends, and boyfriend, and Sadie couldn't take Peanut with her for two years.

Sadie admits that Parker thinks she likes Joe, and Joe responds that Parker isn't his type.

Character Development

Sadie demonstrates remarkable resilience and creative problem-solving. Rather than giving up on the portrait, she researches neuroplasticity and develops three distinct strategies to bypass her face blindness. She also shows vulnerability by sharing her painful history with Parker, and her protective instinct toward Joe is evident when she warns him about Parker.

Joe reveals a deeply wounded past. His wife's infidelity and abandonment explain his empty apartment and his initial gruffness. His caregiving nature shines through as he blow-dries Peanut, leaves clothes for Sadie, and orders her favorite food. His response to Sadie's confession—graciously not calling her out on her feelings—shows emotional intelligence.

Parker is confirmed as a manipulative predator. Her fake fainting, her history of framing Sadie, and her targeting of Joe all paint a consistent picture of calculated cruelty.

Themes, Symbols, or Motifs

Betrayal and trust: Both Sadie and Joe have been betrayed by people closest to them—Joe by his wife, Sadie by her stepsister and father. Their shared experience creates a bond.

Rescue and caregiving: Joe rescues Sadie from the hallway, and Sadie warns Joe about Parker. The chapter is full of small acts of care—the jacket, the blow-dryer, the takeout.

Creative problem-solving under pressure: Sadie's three portrait strategies represent her refusal to give up despite her condition.

The empty apartment as symbol: Joe's furniture-less penthouse symbolizes his emotional emptiness after his wife left. He hasn't found a reason to rebuild.

Optimism and resilience: Sadie's insistence on adding yet when Joe says he hasn't found a reason to bounce back.

Why This Chapter Matters

This chapter is a turning point in the relationship between Sadie and Joe. Their dinner conversation reveals both of their painful pasts, creating mutual understanding and trust. It also establishes Parker as a genuine threat, not just a nuisance, and sets up the conflict that will likely drive the rest of the novel. The chapter also raises the stakes for the portrait deadline, as Sadie's three experimental techniques are about to be tested.

Study Questions and Answers

1. Why does Sadie develop three different portrait techniques, and what does this reveal about her character?

Sadie develops three techniques—verbal descriptions, upside-down faces, and a mathematical grid—because she can't rely on her usual visual perception due to her face blindness. This reveals her resilience, creativity, and determination. Rather than giving up or waiting for her condition to resolve, she actively researches solutions and adapts her approach.

2. What does Joe's empty apartment reveal about his emotional state?

Joe's empty apartment—no furniture except barstools and a mattress—symbolizes his emotional emptiness after his wife's infidelity and departure. He gave everything to Goodwill and has lived this way for a year, suggesting he hasn't moved on or found a reason to rebuild his life. It also explains his initial gruffness and his reluctance to engage with others.

3. Why does Sadie tell Joe about Parker's history, and what risk does she take?

Sadie tells Joe about Parker to warn him about the danger she poses. She takes a risk by admitting that Parker thinks Sadie likes Joe, which indirectly reveals her own feelings. Joe's gracious response—not calling her out—shows his emotional intelligence and deepens their connection.
