Ash functions as Jules’s primary foil and the object of her lifelong envy. She is a round, dynamic character who embodies the privilege, grace, and artistic sensibility that Jules covets.

Raised in the sophisticated Manhattan apartment nicknamed The Labyrinth, Ash possesses an effortless confidence and an open-hearted nature that make her the beloved center of the friend group. It is her invitation that grants Jules entry into “the hot little nucleus” (5) of the camp, establishing Ash as an arbiter of status from the outset. Her life appears to be a seamless progression of success, subsidized first by her family’s wealth and later by Ethan’s immense fortune. This financial security allows her to pursue her passion for directing feminist theater without the commercial pressures that force friends like Jules to abandon their artistic dreams, highlighting a key aspect of The Intertwining of Art, Commerce, and Morality.

Beneath this gilded exterior, however, Ash is a character who experiences quiet suffering and significant moral compromise. Her description of her feelings as an overwhelming “onslaught” (9) of water reveals a deep sensitivity that belies her poised demeanor. This vulnerability is tested by a series of personal tragedies: her brother Goodman’s downfall, her son Mo’s autism-spectrum disorder, and the eventual disintegration of her marriage to Ethan. Her most defining action is her decision to hide Goodman’s whereabouts from Ethan for decades and use Ethan’s finances to support Goodman. This long-term deception, born of familial loyalty, creates an irreparable fracture in her marriage and reveals the immense pressure she feels to maintain her family’s perfect facade, even at the cost of honesty with the person closest to her. Ash’s character arc complicates the notion of a charmed life, demonstrating that privilege does not offer immunity from pain or difficult moral choices.

Ethan is the group’s artistic genius, a round and dynamic character whose trajectory from awkward prodigy to media mogul serves as the novel’s primary engine for exploring themes of art, success, and morality. Initially described as “thick bodied, unusually ugly” (6), Ethan’s immense talent and wit make him a beloved figure at Spirit-in-the-Woods. His animation, Figland, is a deeply personal creation born from the pain of his parents’ fraught marriage, symbolizing art as a private refuge. The transformation of Figland into a global media franchise is central to the novel’s examination of The Intertwining of Art, Commerce, and Morality.

Ethan’s career demonstrates how a singular, authentic vision can be commodified, raising complex questions about artistic purity and the responsibilities that accompany wealth and influence. As Ethan becomes powerful, he develops a social conscience, founding the Anti-Child-Labor Initiative. This act of philanthropy is genuine, yet it is layered with the irony that his own fortune is built on merchandise that may be produced under the very conditions he publicly decries. This paradox defines his adult character; he is a moral person navigating a morally compromised world, constantly trying to balance his success with a desire to do good.

A defining and persistent trait is his unrequited love for Jules. From their first meeting, he establishes himself as her protector, and though he marries Ash, his platonic devotion to Jules remains a steady undercurrent. He is the one friend who truly sees and values Jules’s specific brand of wry intelligence. His confession to Jules that he hid when Mo received his autism-spectrum disorder diagnosis, as well as the confession of his melanoma diagnosis, reveals his deep vulnerabilities, showing that even the most successful member of the group is not immune to fear, failure, and tragedy.

Goodman is the charismatic but self-destructive leader of the Interestings during their formative summer at camp. As a catalyst for the novel’s central tragedy, he is a round character whose development follows a downward trajectory, serving as a stark example of Managing Ambitious Expectations of Adult Life.

At camp, Goodman is a “huge and influential presence” (9), admired for his hyper-masculine confidence and rebellious streak. He embodies the effortless coolness and entitlement of his privileged upbringing. However, his arrogance is coupled with a deep-seated insecurity and a lack of discipline, which his father, Gil, frequently criticizes. He confesses to Jules that his parents see him as a “fuckup extraordinaire” (104), revealing the vulnerability beneath his swagger. This internal conflict between his perceived role as a leader and his fear of failure fuels his reckless behavior.

His impulsive nature culminates in the fateful New Year’s Eve incident in which Cathy Kiplinger accuses him of raping her. Goodman’s subsequent decision to flee justice shatters the idyllic world of the Interestings and permanently alters the course of his life, as well as the lives of those around him. Goodman becomes a fugitive, a ghost who haunts the narrative, his absence a constant reminder of squandered potential and the dark secrets that even the closest friendships can hold. When he reappears decades later, he is a “wrecked” man (493), a cautionary tale of how early promise can curdle into a life of regret.

Dennis, Jules’s husband, functions as a foil to the artistic and ambitious members of the Interestings. He is a round, largely static character who represents a different path in life, one grounded in pragmatism, stability, and a quiet endurance that exists outside the frenetic world of creative aspiration.

Introduced as a “regular” (61) guy with no artistic inclinations, he offers Jules a steadfast love that is not predicated on talent or “specialness.” His career as an ultrasound technician is a practical trade, not a calling, chosen after a period of emotional difficulty in college. This practicality provides a crucial anchor for Jules, whose life is often unsettled by her envy and her feelings of artistic inadequacy.

Dennis’s character arc is focused around his long-term experience of clinical depression. His battle with the illness, and the strain it places on his marriage, provides a different kind of narrative tension, one focused on internal, biochemical struggles rather than external markers of success or failure. While he is often an observer of the Interestings’ drama rather than a participant, his perspective is essential. He remains unimpressed by the Wolf family’s wealth and is critical of their moral choices regarding Goodman, offering a clear-eyed counterpoint to Jules’s often-awed perspective. His presence grounds the novel, suggesting that a life of decency, love, and perseverance holds its own profound value, separate from the dazzling but often fraught world of the Interestings.

Jonah is the quiet, enigmatic musician of the group, a round and dynamic character whose journey explores the renunciation of talent as a form of self-preservation.

As the son of famous folksinger Susannah Bay, he is born into a world of artistic expectation and possesses a natural musical ability that seems “effortless” (17). His friends and family assume he will follow his mother’s path to fame. However, Jonah deliberately turns away from music, choosing to study engineering and robotics at MIT. This decision is a central aspect of his character and a key illustration of Managing Ambitious Expectations of Adult Life, though his reasons remain mysterious to his friends for most of the novel. The revelation of his childhood trauma, where he was drugged and his musical ideas were stolen by his mother’s ex-boyfriend, Barry Claimes, reframes his abandonment of music as a necessary retreat from a world associated with exploitation and psychological damage.

Jonah remains the most reserved member of the Interestings, a gentle and observant presence, though this partly stems from the challenge of sharing his vulnerability with others, which he only achieves at the end of his character arc. His brief and chaste relationship with Ash at camp and his later struggle to find a fulfilling romantic relationship as an adult underscore a deep-seated caution and a fear of being overwhelmed. His connection with Mo opens the door to sharing his feelings with others, which marks a significant leap forward in his character arc. Finally, Jonah’s confrontation with Barry and his eventual reconciliation with music, which is encouraged by Ethan, suggests a late-in-life healing, where he is able to reclaim his talent for himself, free from the pressures of commerce and the trauma of his past.
