The foundational nature of Frankie and George’s connection creates tension when their feelings begin to shift from friendship to romance. Having become so fundamental to each other’s lives, transitioning into new roles initially disrupts the foundation of safety they feel with one another, establishing the central romantic arc of the novel. For both Frankie and George, the fear of disrupting a cherished friendship creates a barrier to emotional honesty. For years, they allow their romantic feelings for one another to remain unspoken and unacknowledged—a silence that breeds misunderstanding, conflict, and unintentional hurt. Across the novel, the characters’ romantic arc centers on the idea that true intimacy becomes possible only when they finally risk the foundation of their friendship and articulate their desire for each other. The novel suggests that vulnerability, while frightening, is the only path to authentic connection.

Over time, George’s long-held romantic feelings for Frankie become a source of internal turmoil that manifests in conflict. For years, he writes his feelings for her into unsent letters that he keeps in a locked wooden chest, a secret archive of his devotion. In these letters, he’s able to be clear and unguarded in a way he never allows himself to be publicly, writing, “I love you, Frankie. I love you. I love you. I love you” (382). When Frankie announces her engagement to Nate, George’s fear and hurt manifest in a bitter argument rather than emotional honesty. He attacks Nate and Frankie’s relationship in ways that exacerbate Frankie’s innate insecurities, creating greater distance between them. George exclaims, “I’ve seen you together […] You behave like a domesticated animal. He doesn’t know the real you" (77). By arguing that Frankie can’t be herself with Nate, George triggers Frankie’s fear that her true self will drive Nate to leave her, just as her mother did. Over the years, George confesses his love for Frankie to both of her brothers—and even, eventually, to Nate—but can’t bring himself to be honest with Frankie for fear of losing her friendship.

In contrast to George, who recognizes his feelings but keeps them hidden, Frankie refuses to acknowledge her feelings for George, even to herself. Her attempts to dismiss the depth of her connection to George often lead her to impulsive choices that mask her true feelings and hurt his. As a teenager, she initiates sex with George but frames it as a pragmatic desire to “get it over with” (226). Fortune frames Frankie’s clumsy effort to engage in a desire she can’t verbalize as an attempt to explore her feelings for George under the guise of safe experimentation with someone she trusts. Later, as an adult, her offhand proposal that they enter a “companionable, sexless marriage where [they’re] always in each other’s corner but [they] also give each other freedom” provides another example of this emotional deflection (217). By framing her desire for a lifelong commitment in practical, non-romantic terms, she avoids the vulnerability of admitting she wants more, protecting herself from potential rejection while still trying to secure his permanent presence in her life.

Their dynamic only shifts when they finally risk articulating their feelings directly. The turning point occurs during a hike in the rainforest when Frankie, remembering a promise she made as a teenager, tells George, “I once made you a promise, but I can’t keep it […] I promised I wouldn’t kiss you” (245). By voicing the long-held restriction, she signals her romantic desire for him. The ensuing kiss releases years of pent-up tension precisely because it follows a moment of verbal risk. The act of voicing their desires allows them to move beyond the safety of friendship and toward the more perilous but rewarding territory of romantic love.

For Frankie, expressing her desire to George lays the groundwork for greater emotional honesty with her family, which provides the support she needs to lay her insecurities to rest. When Darwin challenges Frankie to embrace love with George, she admits, “This thing with George…it’s too important to risk screwing up. I need to get it right” (353). To her mother, Frankie admits, “I always knew [George] was attractive, inside and out. But whenever I found myself thinking about him in that way, I ignored it. I forced him into a corner of my mind and never let him out” (379). Frankie’s father provides his own quiet support, telling her, “George is a good egg […] And I love him like a son […] But you can walk away, if that’s what’s right for you. I won’t let anyone pester you about that" (379). Frankie’s willingness to be vulnerable with her family allows her to accept their support, which gives her the strength to embrace romance with George.
