Summary

The chapter opens with a flashback to the last time Evelyn saw her father alive. At nine years old, with a wrist cast scheduled for removal the next day, she sat in his study asking him to explain the difference between lymph and plasma. They talked for an hour, and at the end he reached across the desk for their customary handshake. He had taught her to aim the webbing between thumb and forefinger at his, grip firmly but not tightly, and pump exactly twice—three pumps would betray nervousness. He nodded approvingly and let her leave.

After his disappearance, Evelyn and her mother never discussed him. They closed his study and pretended the house was one room smaller. The absence felt like the crater left by a pulled tooth—something to notice and probe, but not exactly grief. She eventually went to boarding school, where the silence became easier to maintain.

It was only at her father's alma mater, walking halls he had walked and attending classes he had taken, that she felt the loss more acutely. She longed for the weekly hour in his study, the easy answers, the low rumble of his voice explaining things until she understood. And when she solved problems on her own, she missed the handshake—the grown-up feeling of having completed a maneuver that proved both parties knew what they were doing. She missed the certainty of having done something correctly.

In the present, Evelyn arrives at the lab to find Seyed absent. She's relieved. She discards an old stack of résumés, too outdated to be useful, and plans to request fresh ones from Human Resources.

She and Martine prepare to wake the subject, now called Nathan—not Zed. They've agreed to use the name consistently so they won't slip up. Nathan lies in his recovery bed, nearly healed. His wounds have closed quickly because his tissues are still childlike and pliable, a benefit of his newness that won't last. He looks almost exactly like the original Nathan: thick brown hair, long eyelashes, thin lips perpetually curled at the corners.

Evelyn acknowledges the temptation to reshape him. She has complete control over who he will become. She could build a Nathan with more courage, more attention to detail, someone who could keep up with her, someone who would love her again. She could make a public display of reconciliation. But she recognizes that such a person wouldn't be Nathan. The original Nathan was, in her assessment, born to disappoint her at every turn—and extracting that flaw would require making someone entirely new, someone she could never have loved in the first place. So she doesn't change him. This reconstructed man is the closest approximation of the real Nathan they can produce.

They disguise themselves as doctors—white lab coats, surgical masks, caps, a stethoscope. Evelyn takes Nathan off the sedative. He wakes slowly, his mind flexible and ready to accept new stimulus. His eyes find her mask and stethoscope, and his brain categorizes her as a doctor before it can connect her eyes to the complicated memory of Evelyn.

She tells him he was in an accident on his way home from a mountain vacation—a red car with a dent in the hood, driven by a white kid with dark hair, swerving into a crosswalk in the rain. She repeats his name several times to anchor it in his mind. Nathan accepts the story, mirroring her language: a bit fuzzy. Martine brings him water, holding the glass until his grip is sure.

The chapter ends with Nathan asking whether anyone has called his wife.

Character Development

Evelyn shows a rare moment of restraint in this chapter. Despite having complete control over Nathan's identity, she chooses not to improve him, recognizing that a better Nathan would cease to be Nathan at all. This suggests a growing acceptance of imperfection—or at least a pragmatic understanding that a flawless clone would be unconvincing. The flashback to her father reveals the emotional foundation of her need for certainty and validation. The handshake ritual represents the approval she craved and never fully received after his disappearance.

Nathan wakes as a nearly blank slate, his mind described as plastic and impressionable. He accepts the false accident narrative without resistance, mirroring Evelyn's phrasing and trusting her completely. His first question about his wife shows that the implanted identity is already taking hold—he thinks of himself as a married man.

Martine remains largely silent but present, her unshaking hand offering water, her eyes glassy but not red—she knows how to cry without being caught. Her quiet competence contrasts with Evelyn's more analytical approach.

Themes, Symbols, or Motifs

False memory implantation: Evelyn constructs an elaborate, detailed false memory—mountain vacation, red car, white kid with dark hair, headlights in the rain—and Nathan accepts it readily. The chapter demonstrates how easily a plastic mind can be shaped.

Identity reconstruction: Nathan is rebuilt physically and mentally. His name is deliberately chosen and repeated to anchor his identity. Evelyn's refusal to reshape him into someone better is a meditation on what makes a person who they are.

Control: Evelyn has complete control over Nathan's becoming, and she exercises it with clinical precision—from the sedative schedule to the doctor disguise to the carefully scripted accident narrative.

Grief and absence: The father's disappearance left a wound Evelyn never processed. The closed study, the unspoken rules, the boarding school—all are avoidance strategies that echo in her present behavior.

The handshake ritual: A symbol of approval and certainty. Evelyn misses the feeling of having done something right—a feeling she now seeks to manufacture through control over Nathan.

Mirroring language: Nathan's repetition of Evelyn's phrases signals successful imprinting and foreshadows the deliberate shaping of his speech patterns to match the original Nathan.

Why This Chapter Matters

This chapter is pivotal for several reasons. It provides the first extended glimpse of Evelyn's childhood and her relationship with her father, grounding her present-day behavior in a history of loss and unfulfilled longing for approval. It also marks the moment when the reconstructed Nathan is activated—the point of no return for the deception at the heart of the novel. Evelyn's decision not to reshape Nathan into an ideal partner is a significant character choice, revealing a pragmatic acceptance of imperfection that complicates her otherwise controlling nature. Finally, Nathan's closing question about his wife sets up the central dramatic irony of the chapters to come: Evelyn is his wife, but she's standing before him disguised as a doctor, and the truth of their relationship is about to become far more complicated.

Study Questions

1. Why does Evelyn choose not to reshape Nathan into a more ideal partner, despite having complete control over his identity?

Evelyn recognizes that altering Nathan's essential nature would make him someone entirely new—someone she could never have fallen in love with in the first place. She acknowledges that the original Nathan was, in her view, born to disappoint her, but extracting that flaw would destroy his identity. She accepts that this reconstructed Nathan is the closest approximation of the real man they can produce, and that anyone who met a perfected Nathan would sense something was wrong.

2. How does the flashback to Evelyn's father illuminate her motivations in the present?

The flashback establishes Evelyn's lifelong pattern of seeking certainty and approval through ritual—the handshake that proved she had done something correctly. Her father's disappearance left an unprocessed wound, symbolized by the closed study and the family's silence. In the present, Evelyn exercises complete control over Nathan's identity, a form of certainty she never had with her father. The handshake ritual represents the validation she craved and now seeks to manufacture through her scientific work.

3. What does Nathan's final question about his wife reveal about the success and implications of the memory implantation?

Nathan's question shows that the false memory implantation is working—he accepts the accident narrative and immediately thinks of his wife, demonstrating that his identity as a married man is taking hold. But it also creates dramatic irony, since Evelyn is his wife in the public narrative, yet she's standing before him disguised as a doctor. The question forces Evelyn to confront the deception she's perpetrating and sets up the complications of the chapters ahead.
