Friendship and Betrayal in The Coworker: A Thematic Analysis

Thematic Claim: The Fragile Border Between Friendship and Betrayal

In The Coworker, Freida McFadden weaves a psychological thriller around the idea that the desperate need for connection can poison relationships, turning the very act of seeking a friend into a betrayal of self and others. The novel shows that friendships built on secrets, manipulation, or revenge are not bonds but weapons. Dawn Schiff’s longing for a friend drives her into a toxic dynamic with Natalie Farrell, while her only true friendship—with Mia Hodge—ends in tragedy and fuels a cycle of vengeance. Ultimately, the story suggests that when friendship is used as a mask for betrayal, the two become indistinguishable.

Tracing the Theme Across Three Plot Threads

1. Dawn’s Desperate Attempts to Befriend Natalie

From the beginning, Dawn yearns for Natalie’s approval. In email exchanges with her deceased best friend Mia, Dawn recounts how she tries to win Natalie over: she brings homemade turtle cupcakes to the bridal shower, only to find them thrown in the trash by Natalie. She attends the party despite being explicitly excluded, hoping to make a connection. Natalie’s cruelty escalates—she sends deceptive meeting times to make Dawn appear late, she engineers the destruction of Dawn’s turtle figurines, and she refuses to let Dawn into the bridal shower. Dawn’s response is not anger but continued attempts to “fix” whatever she did wrong. She writes, “I kept trying, but it never works.” This one-sided pursuit reveals the tragic irony: Dawn’s desire for friendship blinds her to the fact that Natalie is using that desire to humiliate her.

2. The True Friendship with Mia and Its Betrayal

The novel’s deepest friendship is the one Dawn shares with her childhood friend Mia Hodge. The emails between them show a supportive, unconditional bond—Mia encourages Dawn to stand up for herself and warns her not to trust Natalie. But this friendship was shattered by betrayal: in high school, Natalie and Tara Wilkes bullied Mia with fake love notes from George, leading to Mia’s suicide. Dawn’s grief transforms into a quest for vengeance. She discovers that Caleb, Mia’s brother, also blames Natalie. Together they plot revenge. Here, friendship becomes a tool for betrayal: Dawn and Caleb’s alliance is built on shared hatred, not genuine connection. Dawn’s loyalty to Mia’s memory justifies her own betrayal of Natalie—yet Natalie had never been a friend to begin with.

3. The Epilogue: A Partnership of Mutual Betrayal

By the end of the novel, Dawn and Natalie reach a stalemate. They exchange secrets: Dawn knows Natalie embezzled from Vixed, and Natalie knows Dawn murdered Tara. In the epilogue, they maintain a “mutual blackmail agreement,” with Dawn stating, “We will keep each other’s secrets to the grave.” This arrangement mimics friendship: they protect one another, attend the same charity 5K, and even smile at each other. Yet it is a hollow performance. Their relationship is transactional, held together by the threat of exposure. The epilogue shows both women unreformed, suggesting that betrayal has become the foundation of their bond. The charity 5K, meant to honor Mia’s memory, instead becomes a stage for their deceit—a symbol of how betrayal can masquerade as community.

Character and Symbol Connections

Characters:

Natalie Farrell embodies the cruel, popular figure who rejects friendship yet craves control. She uses betrayal as a tool—sabotaging Dawn’s cupcakes, lying about meetings, and embezzling money. Her final “friendship” with Dawn is a façade.
Dawn Schiff is the desperate outsider whose longing for friendship makes her vulnerable. Her emails to Mia reveal her loneliness, but also her capacity for violence when betrayed. She kills Tara not just for revenge but to protect the memory of her only true friend.
Caleb McCullough and Detective Santoro represent the aftermath of betrayal—Caleb’s loyalty is tested, and Santoro exposes the lies that friendship often cloaks.

Symbols:

Turtle figurines represent fragility and the desire for connection. Dawn gives them as gifts; Natalie breaks them. The shattered pieces mirror the broken trust between them.
The ceramic turtle murder weapon turns a symbol of friendship into a tool of destruction—a literal betrayal of the peace the turtle once represented.
The charity 5K race is a public performance of goodwill that hides embezzlement and mutual blackmail. It shows how friendships of convenience are propped up by lies.
Blocked phone calls symbolize the isolation and deception that prevent true connection. Dawn’s call for help goes unanswered, and Natalie’s manipulative calls are blocked to avoid accountability.

Complexity and Contradiction

The novel resists a simple victim/perpetrator binary. Dawn is both—she is bullied by Natalie, but she also murders Tara and manipulates Caleb. Natalie is a bully, yet she is also blackmailed by Dawn and ends up trapped in a faux friendship. Their relationship in the epilogue is a contradiction: they help each other avoid prison but also threaten each other. This complexity suggests that betrayal can be both a cause and an effect of twisted friendships. The theme extends beyond the two women: Seth betrays his wife for Natalie; Caleb betrays Dawn’s trust by lying to the police; and even Mia, though dead, is betrayed by Dawn’s violent acts done in her name. The novel implies that once betrayal enters a relationship, it becomes the only language the parties know.

Study Questions and Answers

How does Dawn’s email correspondence with Mia reveal her need for friendship, and why is that need ironic?
The emails show Dawn analyzing every slight from Natalie, hoping to "fix" the relationship. The irony is that Mia, her only true friend, is dead because of Natalie’s cruelty. Dawn’s fixation on befriending the person who destroyed her friend’s life is a self-betrayal.
What role does the turtle figurine play in the turning point of Dawn and Natalie’s relationship?
The turtle figurine symbolizes Dawn’s attempts at friendship. When Natalie breaks it (chapter 18), it marks the point where Dawn stops trying to win her over and begins to see Natalie as an enemy. Later, a ceramic turtle becomes the murder weapon, transforming the symbol of friendship into a tool of revenge.
Does the novel suggest that true friendship is impossible in the world of the story?
The only genuine friendship—between Dawn and Mia—ends in death. All other relationships are based on manipulation or mutual blackmail. The novel implies that when people prioritize self-preservation or revenge, genuine friendship cannot survive.
How does the charity 5K race function as a symbol of false connection?
The 5K honors Mia’s memory, yet it is organized by Natalie, who caused Mia’s suicide. Dawn participates and even wins a proposal from Caleb. The race is a public display of community, but privately it enables embezzlement and keeps dark secrets hidden. It represents friendship as a performance, not a bond.
In the epilogue, Dawn and Natalie maintain a “mutual blackmail agreement.” Is this a form of friendship?
Not in any healthy sense. The agreement mimics the functions of friendship—they keep each other’s secrets and attend events together—but it is based on coercion, not trust. The novel suggests that betrayal can become the adhesive of a relationship, but such a bond is fragile and poisonous, far from genuine friendship.
