Aidan Gardner: The Tragic Artist at the Heart of the Wedding

Overview

Aidan Gardner is the twenty-six-year-old artist son of tech billionaire Errol Gardner and the fiancé of Margaret "Maggie" Szatowski in Jason Rekulak's The Last One at the Wedding. He is introduced as a quiet, bruised young man who speaks little at social events and retreats into his art. Beneath his reserved surface lies a person trapped between loyalty to his dysfunctional family and a buried desire to tell the truth. Aidan's secret past with the missing woman Dawn Taggart, his uneasy arranged engagement to Maggie, and his eventual suicide form the emotional and moral center of the novel.

Plot Role

Aidan functions as the story's mystery engine. His engagement to Maggie draws her estranged father Frank into a web of wealth, lies, and violence. The central questions of the plot—what happened to Dawn Taggart, why Gwendolyn died, and whether the wedding will happen—all circle back to Aidan. He is simultaneously a victim of his family's corruption and a participant in covering up a death. His hidden art studio in the woods serves as a physical symbol of his isolation, a place where he paints portraits of ordinary people as an escape from the moral compromises of Osprey Cove.

Interpretation: Aidan is less an active protagonist than a tragic figure whose inaction and compliance allow the plot's horrors to unfold. His character arc moves from passive compliance toward a brief moment of decisive action that ends in his death.

Motivations and Traits Shown Through Actions

Aidan's primary motivation is protecting his mother, Catherine Gardner. When Frank discovers Catherine's role in Dawn Taggart's death, Aidan confirms that he helped cover it up. He tells Frank that Margaret knows everything and that "we should have been more honest with you" (chapter 33). This suggests Aidan felt trapped by the secret but lacked the courage or means to break free.

His artistic practice reveals his true character. He paints "characters" he spots in Boston—schoolteachers, Uber drivers, nurses, line cooks. He has "an extraordinary memory for faces" and spends days transferring likenesses to canvas (chapter 5). This choice of subject matter—working-class people rather than wealthy elites—suggests a moral sensibility that stands in tension with his family's world.

Aidan is also shown to be anxious and physically fragile. At the rehearsal dinner, he looks "sickly—almost feverish," with a pale face and a rash on his forehead (chapter 31). He drinks multiple cocktails at dinner with Frank (chapter 5) and frequently checks his phone with visible unease. These details, combined with his reported "mugging" in Chicago, paint a portrait of a man under constant strain.

Interpretation: Aidan's anxiety can be read as the psychological cost of living a lie. His art represents the authentic self he cannot fully express, while his public role as Errol's son forces him into a performance he despises.

Chronological Arc

Aidan's arc unfolds across several phases. Before the novel begins, he meets Dawn Taggart after a flat tire, begins a secret relationship with her, and is present when his mother strikes Dawn in a rage, causing a fatal fall down the stairs. He then agrees to cover up the death with Hugo's help, and shortly after, he meets Maggie at a Halloween party. He enters an arranged marriage with her, agreeing to serve as her public husband while she maintains a secret sexual relationship with his father Errol.

During the wedding weekend, Aidan appears increasingly cornered. He argues with Gwendolyn in his studio, threatening her not to talk to Margaret (chapter 18). He receives a threatening photograph of himself with Dawn. He confesses to Frank in the bomb shelter that "I told Gwen the marriage was just for show" and that she refused to play along (chapter 39). He agrees to escape with Frank by boat, but the plan fails when Errol, Gerry, and Hugo arrive. Aidan retreats to the shelter, and a single gunshot is heard.

In the aftermath, Frank learns that a DNA test proved Aidan was not Errol's biological son—a secret Errol kept for years, knowing he was rejecting a child who was not his own (chapter 40). This revelation reframes Aidan's entire life as a search for paternal approval he could never earn.

Relationships

With Maggie Szatowski: Their engagement is a business arrangement, not a love match. Maggie admits to Frank that she agreed to a marriage of convenience with Aidan for financial gain, with a prenuptial agreement guaranteeing a large settlement (chapter 37). Aidan told Gwendolyn the marriage "was only going to last a year" and that he would be free to see other people (chapter 39). Despite this, Aidan shows genuine care for Maggie's family, patiently teaching Abigail to eat lobster and engaging with her questions (chapter 32).

With Errol Gardner: This is the novel's deepest wound. Errol discovered through a DNA test when Aidan was ten that the boy was not his biological son. Instead of confronting his wife or seeking connection, Errol "decided to just leave him to Catherine and focus on my work" (chapter 40). He never told Aidan the truth, leaving the boy to wonder why his father seemed to hate him. Errol acknowledges he "never stopped supporting him financially" but admits no deeper obligation.

With Catherine Gardner: Aidan is fiercely protective of his mother, even though her actions set the tragedy in motion. He covered up Dawn's death to protect Catherine, and Errol notes that "Aidan does look after his mother" and "would do just about anything for her" (chapter 23). This loyalty, while understandable, implicates Aidan in the cover-up and ultimately leads to his death.

With Gwendolyn: The red-haired woman is a friend who urged Aidan to tell the truth. She "was too principled" to accept the arrangement and told Aidan she wanted nothing to do with him unless he "turned [his] back on all the money and told the truth" (chapter 39). Her death—ruled an overdose but suspected by Frank to be murder—removes Aidan's last moral support.

With Abigail: In one of his most sympathetic moments, Aidan teaches the foster child how to eat lobster at the rehearsal dinner, speaking to her "with a gentle tone that was wholly unfamiliar" (chapter 32). This scene reveals a version of Aidan that might have existed without his family's corruption.

Key Decisions and Consequences

Interpretation: Aidan's most important decision—his suicide—can be read as both a surrender and a final act of refusal. He cannot escape his family's control, but he also refuses to continue the performance of being their son.

Theme and Symbol Connections

Aidan's character connects to several central themes of the novel:

Parent-Child Estrangement and Reconciliation: Aidan's relationship with Errol mirrors Frank's estrangement from Maggie. Both fathers fail their children, but Errol's failure is absolute and unrepentant. He rejects Aidan for not being biologically his, a cruelty Frank would never contemplate.

Wealth and Class Divide: Aidan's art focuses on working-class subjects, yet he lives in a penthouse funded by his father's fortune. His paintings of "nurses and teachers and line cooks and bus drivers" (chapter 40) stand in direct contrast to the wealthy wedding guests at Osprey Cove. This tension between his artistic values and his financial dependence drives his internal conflict.

Family Secrets and Cover-Up: Aidan is the keeper of the novel's central secret: that his mother killed Dawn Taggart and the family conspired to hide it. His silence enables the cover-up, and his death ensures it continues.

Moral Compromise and Complicity: Aidan's entire arc is a study in moral compromise. He agrees to the arranged marriage, he lies to Frank, he threatens Gwendolyn, and he allows Hugo to control his life. His suicide, while tragic, also represents the end of his complicity.

Redemption Through Caregiving: Aidan's care for his mother is his one sustained act of loyalty. Even though it implicates him in wrongdoing, it also shows his capacity for love—a quality that makes his death feel especially wasteful.

The hidden studio in the woods symbolizes Aidan's separate, authentic self. It is a space where he paints the people he truly admires, away from his father's surveillance. When Frank discovers it, he finds "all the black-and-white faces of regular people" (chapter 40), a testament to the artist Aidan might have become.

The revolver he retrieves from its locked case is a death object. It represents the violence that has surrounded Aidan—first Dawn's death, then his own. By choosing to use it on himself, he takes control of his fate in the only way left to him.

Book-Specific Questions and Answers

1. Why did Aidan agree to marry Maggie if he was not in love with her?

Aidan agreed to the marriage because it served both his and Maggie's interests. Maggie needed a respectable cover for her ongoing relationship with Errol, and Aidan needed to remain inside the Gardner family structure to protect his mother. The arrangement was transactional: Maggie gained financial security through a prenuptial settlement, and Aidan maintained the appearance of a normal life. He told Gwendolyn the marriage was "only going to last a year" and that he would be "free to see other people" (chapter 39).

2. What was Aidan's relationship with his father Errol really like?

Errol discovered through a DNA test when Aidan was ten that the boy was not his biological son. He never told Aidan this truth. Instead, he emotionally rejected him while continuing financial support. Errol admits to Frank that he "always suspected it" and that discovering the truth was "a genuine relief" (chapter 40). Aidan grew up wondering why his father seemed to dislike him, never knowing the real reason. Their relationship was cold and distant, with Errol focused on work and Aidan left to wonder about his father's indifference.

3. How did Aidan's art reflect his true character?

Aidan painted realistic portraits of ordinary working-class people he observed in Boston—schoolteachers, Uber drivers, nurses, bus drivers. This choice of subject matter showed a moral sensibility opposed to his family's world of wealth and privilege. As Frank reflects after Aidan's death, "With their wrinkles and blemishes and imperfections, they didn't look anything like the wedding guests at Osprey Cove" (chapter 40). His art was an expression of the identity he could not fully inhabit in his daily life.

4. Why did Aidan threaten Gwendolyn, and what did he mean by "stay the fuck away from Margaret"?

Aidan threatened Gwendolyn because she was pressuring him to tell the truth about Dawn Taggart and the cover-up. He feared that if Gwendolyn spoke to Margaret, she would disrupt the careful arrangement that kept the secrets hidden. The threat was born of desperation, not malice. When Gwendolyn later asks if he is threatening her, Aidan immediately softens and tells her to "relax" (chapter 18). His behavior reflects a man torn between wanting to confess and being terrified of the consequences.

5. What led Aidan to suicide in the bomb shelter?

Aiden had reached a point of no return. He had agreed to escape with Frank and tell the truth, but their plan failed when Errol, Gerry, and Hugo arrived at the studio. Trapped and facing the prospect of either continuing the lie or destroying his mother, he chose a third option. His decision to retreat to the shelter and shoot himself was a final refusal to cooperate with the cover-up. It was also, tragically, the only way he could stop being a pawn in his father's games.
