It is Christmas Eve in Chicago, nine years in the past, and Molly is preparing to fly home to Ireland for the holidays. Molly is studying economics at Northwestern University. She buys a last-minute gift of perfume for her identical twin sister, Zoe, before racing to board her plane. Molly’s friend, Hayley, calls asking to borrow a dress for a date with Rob. Molly is confused because Hayley is dating Andrew, who is also Irish. Hayley plans to break up with Andrew after Christmas but is cheating on him with Rob. Hayley’s behavior doesn’t surprise Molly, who has been trying to end the friendship because she sees Hayley as a bad person.
Molly boards the plane and realizes that she is sitting next to Andrew, who is also returning home to Ireland for Christmas. Molly winces, thinking about how she will make it through the long flight knowing that Hayley plans to dump him. Andrew is studying photography and trying to get internships while living with his uncle and working in his store. Andrew asks Molly for help picking out an expensive bottle of perfume for Hayley for Christmas. Andrew’s brother, Christian, has told the airlines it is Andrew’s birthday and to sing to him, but instead the flight attendant offers him drinks. He invites Molly to join in the fake celebration, and they both order wine.
Molly shares that she’s a twin and that her family isn’t very into Christmas. Andrew is from a large family with three siblings, and they love celebrating Christmas. He jokingly calls Molly a “grinch” and vows to make her a fan of Christmas before the flight ends. Andrew’s phone rings, and Molly knows it’s Hayley calling to break up with him. She snatches the phone and ends the call, claiming it’s not safe to use the phone on the plane. The flight attendant arrives with their wine and begins singing “Happy Birthday” just as Hayley begins texting Andrew.
Ten years later in Chicago, Molly is working at a law firm. She’s considering changing careers, but she has no idea what she wants to do. Molly’s coworker and friend Gabriela walks in. Unlike Molly, Gabriela comes from a family of lawyers and loves her work, thriving on the pressure of their workload. Gabriela sees Molly’s suitcase and says she needs a vacation. She reminds Molly that she doesn’t even like Christmas. Molly admits that it’s tradition, and Zoe is pregnant with her first child. Gabriela has noticed Molly’s mood change and asks if she’s pregnant. Molly is recently single, not dating, and not pregnant. Gabriela is a good listener and reminds Molly to reach out if she needs to talk.
Molly gives Gabriela a box of espresso brownies for Christmas, and Gabriela gives her a Cubs teddy bear for Zoe’s baby. Molly leaves the office and muses on her love for Chicago. Though her parents expected her to return to Dublin after college, Molly stayed in Chicago and built a life there. At the airport, Molly purchases a bottle of perfume and walks to her gate, where she finds Andrew reading a National Geographic magazine.
The story flashes back to eight years ago, the second time Molly and Andrew share a flight to Ireland. They haven’t spoken since the awkward situation the previous year. The seat next to Molly is empty, and when she sees Andrew approaching, she prays he doesn’t see her. At first, he doesn’t, but when he sees her face, he moves past without speaking.
In the present, Andrew and Molly are celebrating their 10th anniversary of flying back to Ireland together. Molly’s gift is an upgrade to first-class seats, and Andrew has brought her an antique necklace, the first part of her gift. Their plane is delayed, so they go to the airport bar to catch up. Andrew and Molly both live in Chicago but mostly stay in touch by email and phone. Andrew shares that he has a new woman in his life named Penny. Molly is jealous until he reveals it’s his roommate’s new dog. They discuss their most recent breakups, and Molly shares her disappointment that her ex-boyfriend, Brandon, left her to take a job in a new city. She believes she’s meant to be alone.
Andrew’s dream of becoming a famous photojournalist and traveling the world didn’t pan out, but he’s content working as a lifestyle photographer in Chicago. Molly recalls last year, when their flight was delayed and, out of hunger and exhaustion, she began crying, and Andrew comforted her. She tells him he’s “a good friend” and offers to buy a round of drinks. Andrew shares that he has been sober for two months. Molly feels bad drinking in front of him, but he assures her it’s okay and orders her champagne.
Molly notices that the airport is getting more crowded as more flights are delayed. Andrew calls her over, asking to talk about something, but emergency notifications on her phone distract her. There is a winter storm over the Atlantic, and their flight is canceled. Andrew is hopeful they can get on another flight, but as they search, it’s clear they’re stuck. Andrew is very close with his family, and Molly knows how important Christmas is to them. They prepare to spend the night at the airport, hoping to find a flight the next morning.
The story flashes back to Molly and Andrew’s third flight together seven years ago. When Andrew spots Molly, he doesn’t avoid her and has moved past “whatever indirect role [Molly] played in him dating a shitty person” (51). He asks if she wants to have dinner before the flight. This time feels different as they’ve both grown up. Molly is in law school, and Andrew is working at a portrait studio. Molly is in a new relationship with Daniel and is giddy with new love. They have different seats on the plane, and Andrew suggests they trade so they can sit together. He reminds her of their bet about him convincing her to love Christmas. Molly thinks that for the first time, she’s looking forward to being trapped on a seven-hour flight with Andrew.
In the present, Molly works on her laptop while Andrew waits in a long line to see about alternative flights. Molly calls Gabriela and asks for help finding flights to Ireland. When Andrew returns, she can tell he’s disappointed. She whips out her phone, promising to fix the problem so Andrew can make it home. He takes her phone away, saying there’s no way they’ll get a flight in the next 24 hours. He proposes they stay in Chicago and spend the holidays together. Molly is taken aback, but spending more time with Andrew sounds nice.
Molly and Andrew leave the airport as they make plans to eat “fun food” at her apartment. They pass under mistletoe, and a man nearby says they must kiss or it’s bad luck. Molly moves first, kissing Andrew, and he kisses her back. Molly enjoys the kiss, and it surprises her. Andrew has a tense conversation with his brother, Christian, in the car, and Molly reaches for his hand, suggesting they FaceTime his family from her apartment on Christmas. Gabriela calls, saying she’s found them two seats on a flight to Paris via Buenos Aires, which will circumvent the storm. The prospect of spending two days flying and then finding flights from Paris to Ireland doesn’t entice Molly, but when she sees the hopeful look on Andrew’s face, she concedes. Molly tells Gabriela to book the flights, and they pay the driver $200 to return them to the airport.
When they get to the airport, they can’t find the flight. Molly calls Gabriela, and they realize she booked the flights out of Midway Airport, and they’re at O’Hare Airport. Though there’s no chance they can make it in time, when Andrew pleads with Molly to try, she concedes because she can’t resist how “he’s lit up at the mere mention of his family” (71).
Molly spots the driver who returned them to the airport and asks him to drive them to Midway. At first he refuses, but Molly convinces him by offering a bribe of the fancy truffles she brought to eat on the plane with Andrew. They make it to Midway with minutes to spare, but the attendant says it’s too late to check their luggage. Molly pleads, explaining that her sister is due to give birth soon, and the attendant offers to help get the luggage on the flight. They sprint to the gate only to discover the security line is 45 minutes long. Andrew speaks to the TSA agent, but he is unwilling to help. Molly, overcome with emotion, bursts into tears, and everyone in the TSA line agrees to let them through. They make it to the gate in time. Even after they are on the plane, Molly can’t stop crying.
The prologue establishes Molly as a character wrestling with The Tension Between Self-Definition and Expectations, determined to define herself through her career as she navigates an identity crisis. She is competent and realistic, building her identity on independence and practicality. Yet her annual trip home pulls her into conflict with that identity. Family, romance, and nostalgia become the very forces she tries to hold at arm’s length. Though Molly is unhappy in her work, she is content with the easy rhythm of her friendship with Andrew. Their yearly seatmate tradition is playful, predictable, and safe. Walsh uses their banter and shared history to show how their friendship masks an unspoken longing for connection. By returning readers to the exact moment the friendship began—a mix of coincidence, awkwardness, and chemistry—the Prologue also roots the novel in nostalgia, making their eventual romance feel like an emotional inevitability years in the making.
Walsh grounds this early dynamic in emotional tension rather than instant attraction. Molly’s practicality and Andrew’s warmth create an immediate contrast that defines the story’s tone: She intellectualizes feelings, while he experiences them directly. Their easy rapport is comfortable but charged, revealing how humor can conceal deeper vulnerability. Even the act of sharing wine at 30,000 feet functions symbolically; it is elevated, fleeting, and a space where both can admit things they’d never say on the ground.
Underneath Molly’s casual tone, she keeps her emotions carefully managed; she enjoys Andrew’s company, but she also relies on the friendship as a shield against getting too close. Molly’s independence and wit help her avoid and control what love might disrupt. This emotional restraint reveals The Benefits of Surrendering Control and sets up a slow-burning development of their connection. Their friendship is built on their shared Irish heritage, their history of traveling home together, inside jokes, and an emotional comfort that neither has dared to risk by admitting deeper feelings. Yet when mistletoe offers an opportunity for a kiss, Molly takes it, saying “I’ve been so starved of human contact that the moment Andrew and I come together, things start to get…different” (61). The kiss marks the moment when friendship begins to blur into romance, and Molly starts to question her platonic feelings. Her reaction is as much fear as excitement, offering an early glimpse at the vulnerability she has suppressed beneath her competence. The moment redefines their relationship through the loss of control she’s spent the whole novel resisting.
This first act also establishes the story’s structural rhythm of motion and interruption. Every time Molly thinks she understands the pattern of her life—career, friendship, family obligations—circumstance intervenes. The snowstorm and travel chaos externalize her inner instability. Walsh uses setting as pressure: Airports, cramped taxis, long lines, and delays become emotional crucibles. Through these interruptions, the novel argues that love and self-understanding rarely unfold in ideal conditions; they emerge in the messy, unplanned moments the characters can’t control.
The flashbacks to past flights and Christmases reveal how Molly and Andrew’s friendship developed over the years. These memories starkly contrast with the current chaos, forcing Molly to confront her usual plans for getting home. Molly always has a plan, but the historic snowstorm disrupts everything when she’s already feeling emotionally fragile. She’s less sentimental about Christmas, more practical, more reserved in her connection to her family, and is unbothered by the possibility of canceling her trip. Her internal conflict develops when she sees Andrew’s sadness at not being with his family. She sets aside her desire to spend Christmas alone with Andrew, instead prioritizing her sense of duty to help him get home. This moment subtly exposes Molly’s instinct to nurture: She expresses affection through problem-solving and logistics rather than overt emotion. Her decision to help Andrew, even at great inconvenience, reveals that her care for him already outweighs her cynicism about the holiday.
The snowstorm that derails their plans functions as both a literal and symbolic interruption. Walsh transforms a familiar travel-romance setup into an emotional moment. Stripped of their annual routine, Molly and Andrew are pushed out of their comfort zones. As the journey grows more chaotic, the barriers between them thin, evidenced by Molly’s breakdown as they race to make their flight to Buenos Aires. She thinks, “now that I’ve opened the floodgates, hell if I know how to close them again. Oh God, did I just break something inside? Is this just who I am now?” (81) Walsh uses the physical closeness of travel to heighten awareness of how friendship can evolve when people are pushed to their limits. The physical closeness and logistical chaos of the airport force them to depend on each other as they share tight spaces, solve problems, and make quick decisions. The forced proximity puts emotional tension and attraction under pressure, accelerating their intimacy. By pushing Molly into a state of unplanned vulnerability, Walsh begins translating her professional burnout into emotional openness, and Molly begins to learn that control can coexist with tenderness.
Structurally, these chapters also begin developing the motif of air travel as transformation. Every flight, taxi, or delay becomes a mirror for emotional progress. Movement itself becomes the condition through which Molly can access growth. Her forward momentum with Andrew—physically crossing borders and time zones—mirrors her emotional progress toward risk and connection.
The yearly ritual of flying home to Ireland for Christmas serves as a narrative framework that anchors Andrew and Molly to their past selves, thereby deepening the emotional stakes of the story. Yet beneath the humor and tradition lies a subtle melancholy. For Andrew, home represents comfort, connection, and the security of family, ritual, and affection. For Molly, home is complicated. Returning each year highlights what she has built away from it: her independence, her chosen life in another country, and her emotional distance from the expectations that home embodies. Molly feels distant from the sentimental weight of Christmas, and the trip becomes an unintended reckoning with the distance from her family. When Andrew remarks, “it also sounds like you’re doing Christmas wrong” (12), he gestures to more than Molly’s surface-level cynicism about the holiday. His teasing identifies the quiet sadness in her detachment, a symptom of her burnout disguised as practicality. The scene positions Andrew as the emotional foil to Molly’s restraint. He is playful where she is guarded, expressive where she is efficient. Their contrasting worldviews drive the tension that fuels both their humor and their growth.
The contrast between their attitudes toward Christmas underscores The Emotional Significance of Homecoming. Molly’s detachment from the season exposes her growing distance from her family and from the sense of belonging the holiday represents. Her willingness to use money and gifts meant for her family to barter and bribe their way onto a flight, motivated by a desire to help Andrew rather than herself, reveals both her avoidance of home and her instinct to connect through acts of care rather than sentiment. The Christmas setting brings out Molly’s deepest fear of being alone. Beneath her jokes and easy dismissal of the holiday is concern about what it means to be without a partner. Her indifference is self-protection; it’s easier for her to mock the season than to admit how much she wants the closeness it promises, especially in her annual flights with Andrew. Molly’s struggle isn’t really with Christmas itself, but with what it stands for, which she is missing yet sees that Andrew has. His warmth and easy affection for family traditions, along with his genuine excitement about going home, highlight what Molly feels she’s missing. In this contrast, Walsh quietly suggests that love and homecoming are inseparable, and Molly’s resistance to one mirrors her distance from the other. The first act, then, doesn’t just set up a travel misadventure; it charts the beginning of Molly’s emotional return to herself through the disruptive force of love.
