Summary

Elsie wakes in Jack’s bed after the snowstorm, disoriented and embarrassed by their intimate sleeping position (he is spooning her and has a morning erection, which she mentally dubs a “peerection”). She escapes to the bathroom, finds an email from a student’s mother, and stress‑snoops Jack’s cabinets. Later, Jack makes her toast and coffee (she hates coffee but pretends to like it). He offers her a full‑time research position at MIT, which she refuses because working for “Jonathan Smith‑Turner” would betray Dr. L. and her own identity as a theorist. He then asks her on a date; she also declines, overwhelmed by his motives. Jack is called away by his grandmother Millicent’s fake emergency (she needed sugar for coffee). At Millicent’s house, Elsie learns that Jack’s biological mother, Grethe, was a theoretical physicist who died when he was one. Millicent reveals that Jack was raised to believe Caroline was his mother until she screamed at him that she wasn’t, breaking his trust in lies. Elsie sees the warmth between Jack and Millicent despite their bickering. On the way home, Elsie panics at the thought of never seeing Jack again and blurts out that he can take her out. Jack agrees on one condition: she must be completely honest with him, no pretending to be someone else. Elsie accepts, terrified but willing to try.

Character Development

Elsie: Begins to question her lifelong habit of hiding her true self. She admits to Cece (via text) that she stayed with Jack. Her panic at losing Jack’s presence shows how deeply he has affected her.
Jack: Demonstrates patience, vulnerability, and a strict boundary against lies, stemming from his childhood trauma. His offer of a job and later a date reveals genuine interest in Elsie beyond the fake girlfriend arrangement.
Millicent: Portrayed as sharp, isolated, and manipulative (fake emergencies for attention), yet deeply loving toward Jack. She provides crucial backstory about Grethe and Jack’s distrust of dishonesty.
Elsie’s family: Briefly mentioned as a reason she must stay in Boston—her mother and brothers are “shit shows” she feels obligated to care for.

Themes, Symbols, or Motifs

Heat transfer: The chapter title mirrors the warming intimacy between Elsie and Jack. Physical heat (his body, the heated car seat, the tea Jack makes) parallels emotional thawing.
Honesty vs. pretending: The central conflict. Jack’s demand for “no lies” clashes with Elsie’s default as a people‑pleaser. The lie about coffee, her fake persona with Greg—all are called into question.
Family secrets and boundaries: Millicent’s deception about Grethe echoes Elsie’s own habit of keeping parts of herself hidden. Jack’s insistence on calling his grandmother by her first name is a boundary against false intimacy.
The “peerection” embarrassment: A comic symbol of the raw physical tension between Elsie and Jack, eventually leading to a more honest emotional connection.

Why This Chapter Matters

Chapter 17 is a turning point. Elsie stops running from Jack’s interest and agrees to a real date, albeit with dread. The revelation about Jack’s mother reframes his antagonism toward theorists (the Smith‑Turner Hoax) as an act of teenage rebellion against his mother’s identity, not a professional vendetta. The condition of “no lies” sets the stage for Elsie’s future growth. Millicent adds depth to Jack’s character and shows that even a prickly, money‑obsessed grandmother can be a source of love. This chapter advances both the romance and Elsie’s internal arc toward authenticity.

Study Questions and Answers

Why does Elsie initially refuse Jack’s job offer and date invitation?
She feels loyalty to Dr. L., who despises Jack professionally, and she is terrified that Jack’s interest is a fetish or a game. Her own deep‑seated fear of being known also drives her refusal.
What does Millicent reveal about Jack’s childhood, and how does it explain his demand for honesty?
Millicent reveals that Jack’s biological mother (Grethe, a theorist) died when he was one. His father remarried Caroline, who later screamed that she was not his mother. This betrayal made Jack distrust lies and value clear boundaries and truth.
What does Elsie finally agree to, and what condition does Jack impose?
Elsie agrees to go on a date (or “hang out”). Jack imposes one condition: she must be completely honest with him—no pretending, no hiding her true thoughts—even if she cannot always say them out loud.
