Sky’s thriller series All Her Fault, starring Sarah Snook and Jake Lacy, concluded its first season on November 7, 2025, resolving the mystery of young Milo’s disappearance. The series began with a seemingly straightforward kidnapping investigation that evolved into a complex story of deception, hidden identities, and shocking family secrets. Milo, the central figure in the plot, became the link connecting a web of lies and morally gray decisions, culminating in a finale that left viewers both satisfied and unsettled.
Kyle and Carrie’s Connection
Episode 4 deepened the intrigue surrounding Kyle, a mysterious man with a troubled past linked to Milo’s kidnapping. Detective Alcaras learned from Kyle’s former foster mother, Esther, that while Kyle had no known connection to Milo’s family, he had been visited in prison by Carrie, Milo’s nanny, just before his release. This connection raised suspicions about their potential involvement in the crime.
The episode escalated tension when blood was discovered in Carrie’s rented home and a body was found in a nearby lake. Detective Alcaras also faced his own moral dilemma, secretly switching evidence to help his son secure a school placement. The episode set the stage for a shocking revelation in the finale about Milo’s true origins.
Carrie as Milo’s Mother
In the season finale, the truth about Milo came to light. Carrie Finch, whose real name was Josephine Murphy, was revealed to be Milo’s biological mother. Years earlier, a car crash involving Marissa and Peter led Peter to mistakenly take Carrie’s infant, believing his own child had died. Carrie survived and discovered later that Milo was alive and being raised by strangers.
When Carrie confronted Peter and Marissa, chaos ensued. Peter fatally shot Carrie, claiming self-defense, but Marissa soon uncovered the truth about Peter’s past crimes, including the murder of Carrie’s father.
Peter’s Death and Marissa’s Justice
The finale delivered a chilling twist as Marissa orchestrated Peter’s death by replacing his EpiPen with an expired one. When Peter suffered an allergic reaction, he died, symbolically ending his cycle of manipulation and control. Detective Alcaras ultimately chose to close the case, acknowledging Marissa’s moral struggle while allowing her to move forward with Milo.
Analysts noted that the finale masterfully blended suspense and morality. Milo’s story highlighted how love, grief, and guilt can lead to extreme actions, and how uncovering the truth can offer both closure and tragedy.
Impact and Significance
The ending of All Her Fault underscores the consequences of obsession and deception. Marissa’s morally complex decisions allowed her to reclaim some measure of justice while illustrating the fine line between protection and revenge. For Milo, the resolution offered safety and a path forward with the woman who raised him, free from Peter’s destructive influence.
Detective Alcaras’ moral choices throughout the season, especially his handling of evidence and support for Marissa, reflect the recurring theme of balancing justice with compassion. The series leaves audiences reflecting on how truth, even when delayed, can reshape lives and moral understanding.
What’s Next for All Her Fault
Sky has not officially confirmed a second season, but the popularity of All Her Fault suggests potential follow-ups exploring remaining character arcs. Viewers remain eager to see how Milo adapts to life with Marissa and whether Detective Alcaras’ choices have further consequences. The series’ complex narrative ensures that any continuation will likely maintain its suspenseful and morally intricate storytelling.
