Tyler wakes up in the afternoon to find Katie in his arms. She explains that she turned off his alarm and went into the city to tell her mother about their relationship. Internally, Tyler panics, as he had his own plan to reveal the full truth of their past. Katie recounts how her mother gave her an ultimatum to choose between him and her family. Instead of revealing his own anxieties, Tyler kisses her tenderly, imagining an alternate past where they were a normal high school couple. They spend the rest of the day in bed, but as Katie sleeps that night, Tyler feels a sense of impending doom.

Katie wakes to an empty bed and, after a frantic search of the property, finds Tyler sitting on the floor of the cottage. He breaks up with her, claiming her mother is right and that he cannot take another child away from her parents. Devastated, Katie presses him for an explanation. The conversation becomes a heated argument in which she calls him a coward and accuses him of using her only to discard her again. Tyler reveals his fear that attending the gala would revert him to being the 17-year-old who crashed the car and “decided to start fucking [Mikey’s] little sister” (342)—a characterization that prompts Katie to demand whether that is all she is to him. Piecing things together, Katie realizes her mother was involved in their original breakup. Tyler confesses that after Mikey’s funeral, Carolyn forced him to disappear from Katie’s life. The deal required him to break Katie’s heart so that she would hate him, making the abandonment seem entirely his fault. He admits he is a “trope” who wanted a clean slate he didn’t deserve. Katie tries to reassure him, but he rejects her comfort. As she leaves, she tells him that on the day Mikey died, her mother had declared her own life over, meaning Carolyn had nothing to lose by orchestrating Katie’s heartbreak.

The renovation of the Inn is almost complete. However, this fact is revealed to be unimportant. The narrative clarifies that the project was never truly about the building itself. Instead, the Inn is merely a setting or pretext within the context of a love story.

Katie stands in distress at the end of Meredith’s driveway and makes a phone call. The unidentified person on the other end expresses concern for her. Katie asks if they can meet her at home, and after clarifying that she means their “Long Island home” (348), she confirms the location for their meeting.

Tyler packs his things to leave the cottage. After returning books to Meredith’s library, he strips the bed and makes a discovery. He finds glitter and long strands of auburn hair in the sheets, which causes him to make a sound of heartache. He then folds the linens, places them on a pouf, and closes the cottage door, having now left.

Katie and Ingrid, Mikey’s former girlfriend, arrive at Katie’s childhood home. A woman now living in the house with her baby kindly lets them inside after Katie explains she grew up there and never had a chance to say goodbye.

Tyler paces at the entrance to Meredith’s property while on the phone with his sponsor, Arthur. Seeking validation for his actions, Tyler tells Arthur he ended things with Katie because he thought he could turn back time, but Arthur only asks what he was thinking.

In Mikey’s old bedroom, now a nursery, Katie is overcome by memories of her brother, realizing that all of them are tainted by jealousy and anger related to Tyler. She accepts that she and Mikey were never close and finally allows herself to grieve him fully. In this moment of clarity, she understands the depth of her parents’ and Tyler’s pain. She turns to Ingrid and asks her to tell her “everything” about Mikey.

In a flashback to eight years prior, Tyler recalls the days following Mikey’s death. At the funeral, Katie, sitting several rows away, silently pleads for him to join her. He mouths that he will meet her on the beach later. After the service, Carolyn confronts Tyler and his mother, Marcy—addressing Marcy first, demanding to know how she gets to keep her son while Carolyn’s is “in a casket” (357). Carolyn then turns on Tyler, viciously blaming him for Mikey’s death, calling him a murderer, and forbidding him from ever contacting Katie again. She insists that breaking Katie’s heart is the only way to make her let him go. Marcy never defends Tyler throughout the confrontation, a fact Tyler registers with pain. Afterward, Tyler notices his mother has been distracted, staring at a stylish blond woman in the dwindling crowd.

Furious, Tyler confronts Meredith in the carriage house, demanding to know her connection to his family. He forces his way into her upstairs office and discovers a massive plot wall that meticulously maps out his and Katie’s lives with timelines, notes, and romance tropes. Believing he is hallucinating, he then finds a photo of Meredith with his father, a toddler building sandcastles who is clearly him, and a cat with its tail up. Meredith confesses that Tyler’s father was the love of her life. She then reveals that she met Mikey in a treatment center. Tyler finds manuscript pages on the desk beside a loaded typewriter and demands to know how Meredith could have written his and Katie’s story. To prove her power, he asks her to sit and type his thoughts in real time. She does so, reading each word aloud as the typewriter clacks. As Tyler listens, he realizes that Katie’s unwavering goodness has always forced him to confront his own self-loathing. Meredith types that he was never “born rotten” but took “a wrong turn,” and that he repeatedly pushed Katie away because he believed she deserved someone better. She reminds him that she “only set the scene” and that he and Katie “wrote [their] own love story,” before urging him to fight for Katie instead of continuing to punish himself (374-76).

Lying on the floor of Mikey’s bedroom, Katie listens as Ingrid finishes telling her stories. After Ingrid runs out of stories and is left crying in the evening light, Katie breaks the silence by asking if she has a ball gown.

In Meredith’s office, Tyler realizes he would have left Katie eight years ago even without Carolyn’s intervention. He notices the trope “Meddlesome ghost” on the plot wall, and Meredith reveals her true nature. She explains that after seeing Tyler and Katie at Mikey’s funeral, she decided to orchestrate their reunion. Her plan was executed through her proxies, Selma and Alan. Meredith explains that her supernatural state began when she saw Tom, Tyler’s father, swimming in the ocean: “[A] part of me never came back” (372), she tells Tyler—her body remained in the ocean, and the rest of her became whatever she is now. Meredith urges him to go to Katie, relaying that Mikey told her in treatment that he knew Tyler was good and wanted Tyler and Katie to be together. Finally breaking down, Tyler admits how much he misses his friend, and Meredith tells him it is not too late to fix things.

Henry has realized and publicly declared that he has been in love with Willa his entire life. The outcome of their relationship is now uncertain, hanging entirely on Willa’s decision. He waits to see if she will accept him or reject his confession as being too late. Her potential rejection is based on the significant pain he has caused her on two separate occasions in the past.

Katie and Ingrid arrive late to the gala. Carolyn pulls Katie into the kitchen, assuming Tyler has abandoned her and claiming she was right all along. Instead of arguing, Katie tells her mother that she loves and forgives her for not being able to love her back. She acknowledges Carolyn’s grief, assures her that she will be okay, and gives her a brief hug before letting go.

Anxious to reach Katie, Tyler is with his driver, Maurice, when their car comes to a dead stop in traffic on the Long Island Expressway. Maurice reports that the tunnel is closed; when Tyler asks about the Queensboro, Maurice says that too is closed, and going through Brooklyn is also ruled out. Panicking, Tyler wonders if Meredith has magically orchestrated the gridlock as a test. Maurice says it is just a typical Saturday night. Realizing he is still a river away from Katie and trapped in the car, Tyler demands to be let out onto the expressway.

As the gala ends, Tyler bursts into the ballroom, drenched and holding a bouquet of flowers. He professes his love for Katie just as Carolyn appears and orders him to leave. Tyler apologizes sincerely to both of Katie’s parents but stands his ground, refusing to keep punishing Katie for the past. To everyone’s surprise, Katie’s father, Paul, steps in. He tells Carolyn to let them go, then tearfully hugs Katie and apologizes for his absence in her life. Paul then embraces Tyler, telling him he is glad to see him. He gives the couple his blessing to leave and work things out.

On the sidewalk, Tyler delivers a passionate, rambling love confession to Katie, who happily accepts. As they talk, Maurice pulls up in a Range Rover to take them home. In the car, Tyler gently explains that Meredith is not who they think she is and that she will not be at the estate. As they arrive, the car dissolves, and the house is abandoned and decrepit. They find Meredith’s office empty except for a typewriter and a finished manuscript titled Tropesick. A note from Meredith is attached, calling their story her favorite and wishing them a happy life. They sit on the floor and read their story together as the stars fade and the sun rises; throughout, Tyler simply holds Katie.

One summer later, Katie and Tyler are on a Long Island beach, writing in their notebooks. Katie asks if they could have found their way back to each other without Meredith’s intervention. Tyler believes their story needed “a little magic” (395). Katie wonders aloud whether Meredith knows they are happy—that Tyler sold his book, that he goes to Mets games with her dad, that she is working on her own novel, that he has a tattoo of a pink-gold window on his shoulder. Tyler reassures her that Meredith knows. When they finish working, they collect the cat and take the train back home to Manhattan.
