As a protagonist and narrator, Grace Ivers is a dynamic and round character whose arc exemplifies The Journey from Insecurity to Self-Empowerment. When she begins her freshman year at Briar, she is a self-described “good girl” (13), defined by her cautious nature, her tendency to babble nervously around attractive men, and a life lived largely in the shadow of her more adventurous best friend, Ramona. Her initial interactions are marked by a deep-seated insecurity and a fear of making mistakes, which paradoxically causes her to embarrass herself in social situations. She yearns to break free from the restrictive upbringing instilled by her father, thinking, “I’m supposed to be having fun and making mistakes and ‘finding myself,’ but I haven’t done jack shit this year” (13). This desire for new experiences serves as the primary motivation for her character’s growth throughout the novel.

Grace’s transformation from a passive observer to an active agent in her own life is spurred by her tumultuous relationship with John Logan. After he callously rejects her, the painful experience becomes a catalyst for self-assertion. When Logan seeks a second chance, Grace she presents him with a list of tasks he must complete to earn her trust, a pivotal moment that signals her shift in power. This act demonstrates her newfound confidence and her refusal to be treated as a disposable hookup. Her personal growth is also marked by a necessary, albeit painful, break from her friendship with Ramona. By creating distance through the trip to Paris, Grace learns to make her own decisions and define her own identity, separate from her friend’s influence.

By her sophomore year, Grace is a more self-assured woman who understands her worth. She forges new friendships with Daisy and Morris, through whom she gets a job and explores her creative interests. Her evolution is reflected in her willingness to initiate sexual encounters with Logan, a stark contrast to her earlier insecurities. She learns that building a healthy partnership is contingent upon first finding her own voice and advocating for her own needs and boundaries. Her journey from a shy girl watching action movies alone in her dorm to a confident woman demanding respect from a star athlete illustrates that self-empowerment is about using that confidence to actively shape one’s life and relationships.

A central supporting character, Dean is a round and static figure who embodies the trope of the wealthy, hedonistic playboy. He is unapologetically vain, drinks excessively, and pursues women with a singular focus on pleasure. His carefree lifestyle provides a sharp contrast to Logan’s concealed anguish, highlighting the different ways the characters cope with their realities. While Logan’s womanizing is a symptom of his inner turmoil, Dean’s appears to be a genuine lifestyle choice, driven by a desire to enjoy the perks of his status as a popular hockey player. He is the source of much of the novel’s comic relief, offering brazen and often ridiculous advice about women.

However, Dean’s character is given significant depth, aligning with the theme of The Discrepancy Between Public Personas and Private Struggles. His strict “no-freshmen rule” (11), which appears to be an arrogant policy, is revealed to be a protective measure stemming from a traumatic experience with a freshman stalker. This backstory reframes his behavior, showing that his flippant persona is, in part, a defense mechanism. Despite his seemingly superficial nature, Dean proves to be a fiercely loyal friend. He is attuned to Logan’s moods and, along with Tucker and Garrett, forms a critical support system. His decision to confront the rumors Piper Stevens spreads about Grace demonstrates a protective instinct that goes beyond his typical self-interest, solidifying his role as more than just a source of comic relief. Dean’s story is more fully explored in The Score, the novel following The Mistake in Kennedy’s Off-Campus series.

As Grace’s best friend and foil, Ramona is a dynamic and round character whose development is secondary but parallel to Grace’s own. Initially, she fits the “bad girl” trope, but she thrives through keeping Grace in her shadow. Ramona is portrayed as confident, sexually liberated, and obsessed with social status and hooking up, particularly with Dean Heyward-Di Laurentis. She makes most of the decisions for herself and Grace, steering their social life and appearing to encourage Grace to be more adventurous. However, this domineering friendship stifles Grace’s ability to develop her own identity, creating a dependence on Ramona that Grace must eventually break.

Ramona’s seemingly confident exterior masks deep-seated insecurities, a key element of her character that is revealed as the narrative progresses. Her pursuit of Dean and her need for male attention are symptoms of a desperate need for validation. Her character’s turning point comes after she betrays Grace by propositioning Logan shortly after he has deeply hurt Grace. This act of disloyalty leads to a confrontation where Ramona confesses the motivation behind her behavior: “I’m a jealous, insecure bitch” (159). This moment of raw honesty is crucial for her arc, as it forces her to acknowledge that her actions stem from envy of Grace rather than genuine confidence. Although their friendship is irrevocably altered, this confession allows for the possibility of a more mature and honest relationship in the future, marking Ramona’s first step toward genuine self-awareness. Though Ramona later decides to party with the hockey team from St. Anthony’s, necessitating Logan and Grace’s intervention, this event marks Ramona’s separation from her unreliable friends, reversing the former paradigm of her friendship with Grace.

Garrett is a key supporting character who functions as a loyal friend and moral anchor for Logan. As the captain of the Briar hockey team and the romantic partner of Hannah Wells, he represents a stable, aspirational ideal that Logan initially envies. Garrett’s own life is not without its struggles, as hinted by his difficult relationship with his father, but he navigates his responsibilities with a maturity and focus that contrasts with Logan’s self-destructive tendencies. He is consistently supportive of Logan, offering encouragement about his professional hockey prospects and creating a space of camaraderie within their shared house. Though he is initially unaware of the depth of Logan’s family troubles, his unwavering friendship provides Logan with a crucial sense of belonging and normalcy amidst his private turmoil. Garrett’s story is more fully explored in The Deal, where he is a protagonist. His role in The Mistake is, in part, an exploration of his life after the events of the prior novel.

A supporting character and one of Logan’s three roommates, Tucker serves as the pragmatic and observant voice of reason. He is the first to directly confront Logan about his self-destructive behavior, including his excessive drinking, womanizing, and his unhealthy fixation on Hannah. In an early conversation, Tucker cuts through Logan’s denial, stating, “You can’t screw her out of your system, man” (6). Unlike Garrett, who offers more optimistic encouragement, Tucker provides blunt, grounded advice. His presence in the house ensures that Logan cannot completely lose himself in his despair, as Tucker consistently holds him accountable for his actions. Though he has a smaller role, his steady, no-nonsense friendship is essential to Logan’s support system, and he is willing to have more candid conversations with Logan about his life. Tucker is the main character of the fourth book in the Off-Campus series, The Goal.
