In a Paris hospital room in 2039, Ari recounts her criminal past to Nico, who has come to visit her after the explosion that killed Soriano and shattered Ari’s leg. Ari explains that after the 9/11 attacks in New York, she started a business selling US passports obtained through a corrupt post office clerk named Luis, along with her friend Ilieva and her cousin Anton. The business escalated when Ilieva was recruited by a Russian criminal to participate in a trafficking operation, illegally smuggling people into the former United States. When Anton, who was assisting with a transaction in Italy, became fearful and threatened to go to the authorities, Ari hired someone to kill him. However, upon her eventual arrest, the FBI informed her that Anton was still alive. Ari now believes the hitman killed Anton’s doppelgänger by mistake.
Nico shares her own story, revealing she is a physicist who was accidentally transported from a parallel universe. She arrived at a party in Los Angeles, where she saw a doppelgänger of her husband, Kareem, who called her “Gloria,” the name of her double in this world. Nico’s colleague, Saraya, had also been transported but was driven insane by the shock. After Nico’s encounter with Ari in Ohio, she located Gloria online and traveled to Paris to find her. She met Gloria first in a café, then visited her apartment, where she discovered Gloria to be a neglectful, work-obsessed mother to her son. The boy reminded Nico of her own children, Marlowe and Samir, so she became his maternal caregiver. In their final conversation, Ari tells Nico she doesn’t trust anyone.
Sebastian began researching the wealthy philanthropist Ari Soriano at age 15 while at a boarding school in Normandy. He became fixated on stealing back a painting titled Swan Dive, which had been given to Gloria by his father—the only piece of him Sebastian had. Gloria had sold the painting to Ari and Sebastian is determined to get it back. Sebastian questions Nico, who acts as his guardian, about Ari. She tells him about their conversations in Ari’s hospital room all those years ago. Their conversation shifts to Nico’s most recent trip to talk to a Danish physicist who believed objects can be conduits between parallel worlds. She tells Sebastian that Swan Dive hung in the laboratory in her home world: “it's interesting to imagine that perhaps it had something to do with . . . with what happened [but] I think there must be countless objects that exist in both worlds, and I think the painting's a red herring" (136). When Sebastian asks if she loved the painting, Nico says, “I suppose we have that in common, you and I" (137).
Sebastian first attempts to get close to Ari through her wife, a pianist named Eddie Kalisa, whom he cultivates a friendship with across multiple encounters at the opera and an orchestrated meeting in a café. However, Eddie dies unexpectedly, forcing Sebastian to change his plan. Two years later, Sebastian poses as an art history student to gain access to Ari’s apartment. He successfully steals Swan Dive and goes to Gloria’s apartment to hide. Hiding upstairs, he hears Ari enter Gloria’s apartment, waits for her to leave, then sets off with the painting for Nico’s apartment. He stops at a food stand in Vincennes and sees Ari following him. Simultaneously, he sees a man approach and shove her, grabbing her handbag and causing a severe head injury.
Sebastian takes the injured Ari to Nico’s apartment, but Ari adamantly refuses to go to a hospital. He lets her rest in the guest room, where she dies from her injury. When Sebastian enters the room to retrieve the painting, he notices the silence is too still and realizes he is the only one breathing. He also detects a scent of cedar and cigar smoke, as if Eddie Kalisa had just passed through. He brings the painting to Nico for her birthday, lying that he bought it back from Ari. Knowing Ari cannot be found in Nico’s home, Sebastian calls his friend Obie, whose arrives with members of his gang to remove the body. Afterward, Obie’s boss contacts Sebastian to call in the favor, drawing him into a life of crime.
At the moment of death, Ari is in Nico’s guest room, looking at the Swan Dive painting. She reflects on her life, wishing she could return to the LA party to step through the door with Kareem, and wishing she hadn’t tried to have her cousin Anton killed, longing to have been less of a villain.
The ghost of her late wife, Eddie Kalisa, appears and tells Ari they no longer have to be apart. The world of the painting becomes real, expanding into a vast seascape with a diving board extending into it. As her body dies, Ari’s consciousness takes Eddie’s hand, rises, and dives from the board into the ocean.
The transcribed dialogues between Nico and Ari in a Paris hospital room establish their parallel senses of loss. By presenting Ari’s backstory as a recorded conversation, the text emphasizes themes of memory and testimony. The one-sided nature of the transcript, with Nico’s contributions reduced to ellipses, filters the exchange through Ari’s perspective. Ari’s story is a catalog of crimes—passport forgery, human trafficking, and a murder for hire—all rationalized by a desire for what she calls “freedom” (117). This personal history of moral compromises and societal collapse mirrors the broader fragmentation of her world. Juxtaposed with Ari’s confession is Nico’s own story of displacement. Her arrival from a parallel universe positions her as a refugee from a different world, a scientific anomaly defined by a personal loss. Nico’s account of finding her colleague Saraya “completely undone” (120) by the transition emphasizes the psychological trauma of such a displacement. Both women, one a criminal and the other a physicist, recount the loss of their former lives, framing them as inhabitants of worlds that no longer exist for them. This shared experience of exile, one metaphorical and the other literal, connects them as figures haunted by alternate pasts and lost possibilities.
The various characters’ personal connections to the Swan Dive painting foregrounds The Connective Power of Art. For Sebastian, the painting is a tangible link to a father he never knew, and his quest to reclaim it is an attempt to recover a lost piece of his own history. His methodical, years-long plan to first befriend Ari’s wife, Eddie, and then steal the artwork demonstrates the depth of his obsession. For Nico, the painting is a painful memento of her previous life, a beautiful object that “hung in the lab” (134) in her home world—“something [she] loved” (136). Yet, as a scientist, she dismisses the idea of it being a conduit between universes, grounding her grief in rational skepticism. For Ari, the painting, which has served a “her only constant” (78) throughout her life, becomes a metaphorical portal into her death. As she dies, she sees the ghost of her wife, and the world of the painting expands to become her afterlife, an ocean into which she dives.
Ari’s dying reflections highlight The Hope of Multiple Possible Futures, reframing the multiverse through the lens of her regret. In the moments before her death, her consciousness is filled with a desire to “run time backward” (161) and undo the choices that defined her life of crime. She specifically wishes she could go back to the party in Los Angeles and “step through” the door with Kareem, or that she could return to Italy and release her cousin, Anton, from their criminal enterprise. Her longing to have been “less villainous” (161) casts her violent past as a life she wishes she could escape. This desire for a different life path connects with Nico’s experience of having been forcibly ejected from her own timeline. While Nico’s displacement is a scientific accident that separated her from her children, Ari’s is a moral one she created herself. The science fiction premise of parallel worlds provides a metaphor for the human experience of regret and the contemplation of roads not taken, where every major life decision shows a branching point into a different potential self.
Sebastian’s successful theft of Swan Dive and its violent aftermath initiate his descent into a life of crime, demonstrating how a single, consequential act can lead to an alternative path. He initially believes the theft is an act of restorative justice, but the mission immediately spirals out of his control. Ari’s accidental death in Nico’s apartment forces Sebastian into a critical moral choice. To protect Nico and himself, he contacts his friend, Obie, to make the body disappear, a decision that indebts him to a local criminal organization. The call from Obie’s boss to discuss “working with us” (158) confirms that this favor comes at a high price, effectively trapping him in the very kind of life he had hoped to avoid. Sebastian’s quest to recover his father’s legacy leads him to sacrifice his own moral integrity and future autonomy. His final lie to Nico—claiming he “bought it back from her” (158)—cements his transformation, as he presents a noble fiction to the person who represents his conscience while simultaneously embracing a criminal reality.
