Summary

Barrett and Miles drive four and a half hours to Astoria, Oregon, to find Dr. Devereux, a former University of Washington professor who once taught a class on time travel. During the drive, Barrett's mind wanders to romantic fantasies about Miles, and she notices how attractive she finds even his smallest gestures. When they arrive at her house—a quirky yellow home with solar panels, a galaxy-painted fence, and a garden full of clay gnomes holding scientific instruments—they find Dr. Devereux on the porch. She initially assumes they were sent by someone named Amy and insists she won't return to teaching.

After they explain they're students and that they've been trapped in a time loop repeating September 21st, she invites them inside for tea. Her cluttered home is filled with antiques, gadgets, and dozens of clocks, and she introduces her cats, Ada Lovelace and Schrödinger. Over tea, Dr. Devereux shares her two main theories. First, she explains the many-worlds interpretation of quantum mechanics, suggesting that parallel universes exist and that connection points—places where universes nearly touch—might allow information or even people to cross over. She advises that if they could find such a point, they might be able to escape the loop by being there at the exact time of their daily reset, and she suggests following the strongest gravitational pull. Second, she offers a more “magical” theory: that time itself might be a corrective force, nudging them back onto a path they strayed from. She also notes that time loops can distort memories and that physical effects from previous days might linger.

Dr. Devereux then reveals why she left UW: her class was not respected, parents considered it a waste of money, and she grew tired of being called a fraud. She erased herself from the internet and retreated to Astoria. Barrett and Miles express genuine sympathy, and Miles tells her he would have fought to get into her class. Before they leave, Dr. Devereux gives them her phone number, noting that they might reach a different version of her in another universe. The chapter ends with them feeling both closer to a solution and overwhelmed by the uncertainty.

Key Events

Barrett and Miles travel to Astoria to find Dr. Devereux, a former UW professor who taught a time-travel class.
They reveal their time-loop predicament, and she invites them in for tea.
Dr. Devereux explains the many-worlds interpretation and the concept of connection points between parallel universes.
She suggests that being at a connection point at the moment of the daily reset might allow them to escape.
She shares her second theory: time as a corrective force that intervened because they strayed from their intended path.
She discusses how time loops can distort memories and cause lingering physical effects.
Dr. Devereux reveals she left academia because her work was dismissed and she was called a fraud.
She gives them her phone number and encourages them to reach out, though she acknowledges they might contact a different version of her.

Character Development

Barrett shows growing vulnerability and empathy. She opens up about their desperation, feels genuine compassion for Dr. Devereux's painful past, and acknowledges her own romantic feelings for Miles, even as she struggles to interpret his signals.
Miles demonstrates his scientific curiosity and supportiveness. He listens intently, asks clarifying questions, and offers a heartfelt compliment that brightens Dr. Devereux's mood. His physical closeness with Barrett—like brushing ankles and a hand on her back—hints at mutual affection.
Dr. Devereux evolves from a guarded recluse to a mentor figure. She initially assumes they were sent to pressure her, but after hearing their story, she becomes engaged and generous with her knowledge. Her vulnerability about being called a fraud and missing teaching adds depth to her character and creates a parallel with Barrett's own fears of being dismissed.

Themes, Symbols, or Motifs

Parallel universes and infinite versions of self: Dr. Devereux's explanation of the many-worlds interpretation reinforces the novel's exploration of alternate paths and the idea that countless versions of Barrett and Miles exist.
Time as a corrective force: Her second theory suggests that the loop might be a deliberate intervention, adding a layer of purpose to their suffering.
Memory distortion: The chapter highlights how the loop affects their recollections and physical sensations, tying back to earlier hints of lingering pain.
Clocks as symbols: The many clocks in Dr. Devereux's house, which strike at slightly different times, symbolize the fractured nature of time in the loop and the characters' struggle to synchronize with a normal timeline.
Schrödinger's cat: The cat's name nods to quantum superposition, reinforcing the theme of uncertainty and multiple simultaneous states.
Academic exile and the search for validation: Dr. Devereux's story mirrors Barrett's own fears of being dismissed, and her eventual openness suggests that finding someone who believes you can be healing.
Hope vs. hopelessness: Barrett initially feels the situation is hopeless, but Dr. Devereux insists it's merely complicated, offering a fragile but real sense of possibility.

Why This Chapter Matters

This chapter is a turning point in the novel. It introduces a credible scientific framework for the time loop, giving Barrett and Miles a concrete—if daunting—potential solution: locate a connection point and be there at the moment of reset. It also deepens the emotional stakes by showing Barrett's growing feelings for Miles and by humanizing Dr. Devereux, whose past struggles with academic rejection resonate with the novel's themes of being misunderstood. The chapter balances hope with uncertainty, leaving readers eager to see whether the characters can act on this new knowledge.

Study Questions and Answers

What are Dr. Devereux's two main theories about the time loop?

Dr. Devereux first proposes the many-worlds interpretation, suggesting that parallel universes exist and that connection points—places where universes nearly touch—might allow information or even people to cross over. She advises that finding such a point and being there at the exact time of the daily reset could allow them to escape. Her second theory is more metaphysical: that time itself is a corrective force, intervening because they strayed from their intended path.

How does Dr. Devereux's personal history mirror the themes of the novel?

Dr. Devereux left academia because her research on time travel was dismissed and she was called a fraud. This mirrors Barrett's fear of being seen as unreliable and the novel's broader exploration of how people are judged for unconventional ideas. Her eventual openness and willingness to help also suggest that finding someone who believes you can be transformative.

What advice does Dr. Devereux give about how to potentially escape the loop, and what challenges does she acknowledge?

She advises them to find a connection point between parallel universes and to be there at the moment of their daily reset, following the strongest gravitational pull. However, she acknowledges that the location of such points is unknown and that even if they cross over, they might not arrive in the “right” universe, and they could risk disrupting the space-time continuum.
