Summary

Scarlett arrives at the Green Library for the first official meeting of Dr. Smith’s neurobiology project. She pulls up Lukas’s emails and lands on two threads: the ongoing planning messages with Zach, and an older email titled “What you need.” She hasn’t replied to it, but every word is burned into her memory.

Lukas finds her in the corridor, bumps her arm, and calls her “troll” before leading her upstairs. During the meeting, Scarlett relaxes around Zach, whom she now considers fairly unthreatening. She kicks off her shoes, stretches her legs across Lukas’s empty chair, and casually lists her academic credentials—online neural-network courses, bioinformatics club, a comp bio research camp. The group discusses her upcoming MCAT, her disastrous German homework, and the possibility of medical school.

When Lukas returns from refilling water bottles, he lifts her bare ankles, sits, and places her feet in his lap. His thumb traces the ball of her ankle, then slides under the hem of her leggings. Zach, shielded by the table, asks if Scarlett is dating a swimmer. Lukas’s grip turns into a manacle; he answers “She’s not” in a steady voice while fixing her with his eyes. The overt claim sends a wave of heat through her, and she is flooded with contradictory feelings—arousal at his strength, shame at how “heteronormative” it feels, and a deep, undeniable pleasure.

After Zach leaves the room, Lukas reveals that the question was a probe to see if Scarlett was single. He mentions Kent Wu, a former swimmer who asked her out twice; she never noticed. Scarlett insists she isn’t clueless, but Lukas gently points out that she keeps her head down and filters out anything she can’t control. When Zach returns, Scarlett pulls her feet away and folds them beneath her, forcing herself to re-engage with the project.

Key Events

Scarlett checks Lukas’s emails and once again confronts the “What you need” thread.
Lukas calls her “troll” and escorts her to the meeting room, leaving the door open so he can see her from the fountain.
Scarlett feels at ease enough to take off her shoes and joke with Zach.
Lukas lifts her bare feet into his lap and begins a slow, possessive massage under the table.
Zach asks about her dating life; Lukas’s hand clamps down and he answers for her.
Scarlett internally battles shame and longing over her enjoyment of his dominance.
Lukas tells her Zach was gauging her availability and shares the story of Kent Wu’s unnoticed advances.
The conversation highlights Scarlett’s tendency to block out distractions—including her own blind spots.
Scarlett reclaims her physical space just as Zach returns, ending the secret moment.

Character Development

Scarlett displays an intense mix of self-awareness and denial. She recognizes the “sticky” heat between her legs and names her attraction as something that makes her feel regressive, yet she admits she “loves it.” The exchange with Lukas about Kent Wu forces her to confront how thoroughly she tunes out unwanted social signals, a survival tactic that also isolates her. Her final action—pulling away—shows a reflexive retreat to safety, even as she longs for the connection.

Lukas moves from teasing to quiet possession. His actions under the table break the public-student facade they maintain, staking a silent claim that only Scarlett can feel. By raising Kent Wu’s past interest, he demonstrates how long he has been aware of Scarlett and how carefully he observes her, blurring the line between protectiveness and control. His line “You just keep your head down” reveals an intimate understanding of her coping mechanisms, likely fed by Pen’s earlier disclosures.

Zach functions as the unwitting catalyst. His clumsy question about boyfriends ignites Lukas’s jealous streak and gives Scarlett a mirror for her own obliviousness. His easygoing demeanor and nerdy jokes help disarm her, making the sudden physical tension with Lukas all the more jolting.

Themes, Symbols, or Motifs

The “What you need” email stands as a symbol of unresolved desire and the unspoken agreement between Scarlett and Lukas. She refuses to delete, archive, or reply—keeping the possibility alive while denying it a real-world outlet.
Hidden touch and public secrecy magnify the novel’s core theme of a clandestine relationship. Lukas’s massage is invisible to Zach, paralleling the larger secret they keep from their teams and families.
Control and surrender resurface in Scarlett’s monologue about heterosexual norms, dominance, and consent. She wrestles with the idea that finding pleasure in Lukas’s strength is “banal,” yet the absence of victims allows her to embrace it as a safe release.
Obliviousness as armor emerges through Kent Wu’s unrequited attempts and Lukas’s gentle indictment that Scarlett filters out anything she cannot manage. The chapter frames selective attention not as naivety but as a deliberate survival strategy.

Why This Chapter Matters

Chapter 17 places the project meeting in the foreground while letting the emotional undercurrents boil beneath the surface. For the first time, Lukas uses a semi-public space to physically and verbally claim Scarlett, forcing her to confront the depth of his possessiveness and her own response to it. The Kent Wu revelation retroactively recontextualizes earlier interactions—Lukas has been watching her much longer than she realized, and his inside knowledge (likely from Pen) suggests he’s been curating his approach. This chapter deepens the power-exchange thread that runs through the novel and sets up the tension Scarlett will need to reckon with as their arrangement inches closer to the light.

Study Questions and Answers

What does the “What you need” email thread represent, and why does Scarlett refuse to act on it? The email symbolizes the latent desire and the possibility of a deeper relationship with Lukas. Scarlett memorized it but won’t reply, delete, or archive it because doing so would force her to make a conscious choice. Keeping it in limbo lets her remain passive, a pattern that echoes her broader tendency to ignore things she feels she can’t control.
How does Lukas’s possessive grip and his “She’s not” response illuminate the dynamics of their secret relationship? The grip acts as a physical assertion of ownership in the only way available—hidden under a table. By answering for her, Lukas stakes a public-adjacent claim while reinforcing the dominance/submission dynamic that Scarlett both craves and questions. It shows that he is willing to breach their “casual” rules when a perceived threat (Zach’s interest) appears.
Scarlett calls her attraction “heteronormative” and “banal” yet admits she loves it. What does this internal conflict reveal about her character? It highlights her intelligence and self-scrutiny. Scarlett intellectualizes her feelings, applying academic labels to visceral reactions. The conflict shows she hasn’t fully accepted her own desires because she fears they are anti-feminist or regressive. However, her honesty about loving the feeling suggests she is moving toward a more integrated sense of self—one that allows for complexity without guilt.
