The ending of Nocturnal Animals is haunting and layered with meaning, blending reality with fiction in a way that leaves viewers reflecting on the characters' emotional states. Throughout the film, Edward, played by Jake Gyllenhaal, sends a manuscript of his dark, revenge-filled novel to his ex-wife, Susan. Her immersion in the story about Tony, a man driven to seek brutal revenge after the trauma of losing his wife and daughter, mirrors her own feelings about their broken relationship. As Edward mourns his unfulfilled love and professional insecurities, Tony's story serves as a metaphor for his inner pain and desire for vengeance.
In the film’s climax, Edward never appears in person to confront Susan or to exact his revenge. Instead, he allows his novel to act as a cold, emotional strike: Susan reads the story and is left to grapple with her past betrayals—most notably her infidelity with Hutton, her second husband. The film suggests that Edward’s act of giving her this dark, powerful story is his way of telling her that he still harbors deep resentment, but he doesn't seek closure by physical confrontation. His silence and absence at the end imply that the revenge was more about emotional release than about reconciliation.
The finale reveals Susan alone, realizing that her attempt at reconnecting with Edward was doomed from the start. She waits at a restaurant until closing, her solitude reflecting her current emotional emptiness. Meanwhile, the novel’s story, especially Tony’s grim cycle of violence and regret, underscores that revenge often leaves people unchanged and unfulfilled—an idea that resonates with Susan's loneliness and her own moral dilemmas. The story of Ray, Tony’s vengeful antagonist who kills Tony’s family and ultimately dies bloodied and exhausted, symbolizes the destructive nature of revenge. It shows how violence and vengeance only perpetuate pain, leaving characters like Tony—and by extension, Edward—still broken and searching for peace.
Ultimately, Nocturnal Animals doesn’t provide a clear resolution but instead offers a poignant meditation on heartbreak, vengeance, and despair. Both Edward and Tony crave retribution—Edward by aiming to emotionally damage Susan, and Tony by seeking justice for his loved ones. Yet, the film’s ending indicates that revenge is an empty pursuit; both characters are left scarred and unable to return to happiness. The film’s ambiguous conclusion, coupled with its dark themes and layered storytelling, invites viewers to consider whether true closure is ever possible or if everyone is ultimately haunted by their past, destined to remain imperfect, broken souls.
