All Her Fault Season 1 Recap: From Kidnapping to Confession

Episode 4 focused on Kyle, the mysterious man linked to Milo’s kidnapping. Detective Alcaras learned from Kyle’s former foster mother, Esther, that he had a troubled past but no known connection to Milo’s family—until they discovered that Carrie, Milo’s nanny, had visited him in prison just before his release. This revelation tied Kyle to Carrie, deepening suspicions about their involvement.

Meanwhile, Detective Alcaras faced a moral dilemma of his own, secretly switching evidence to help his son secure a school placement. The episode ended with police discovering blood in Carrie’s rented home and a body in the lake, escalating the tension.

By the final episode, the truth about Milo’s origins came to light. Carrie Finch, whose real name was Josephine Murphy, wasn’t just a kidnapper—she was Milo’s biological mother. Years earlier, Marissa and Peter had been in a car crash. Believing their own baby was dead, Peter found a crying infant in another car—Carrie’s—and took him, raising him as Milo. Carrie had survived the crash, only to discover years later that her son was alive and being raised by strangers.

The Final Twist: Peter’s Deadly Secret and Marissa’s Revenge

When Carrie confronted Peter and Marissa at gunpoint, chaos erupted. Peter fatally shot Carrie, claiming self-defense. But Marissa soon uncovered the horrifying truth—Peter had killed Carrie’s father to hide his crime and lied about the entire incident. Peter’s moral corruption and obsession with control led Marissa to exact her own form of justice.

In a chilling final act, Marissa orchestrated Peter’s death by removing his emergency allergy kit and replacing his EpiPen with an expired one. When he suffered an allergic reaction, she watched as he died, symbolically ending the cycle of deceit. Detective Alcaras later chose to close the case, acknowledging Marissa’s moral struggle but silently allowing her to move on with Milo.

Aftermath and Meaning Behind All Her Fault’s Ending

The ending of All Her Fault serves as both a tragedy and a redemption story. Marissa, though morally compromised, finally reclaimed her freedom and truth. The series explored how grief and guilt can twist love into obsession and how the desire to protect can lead to destruction.

For Detective Alcaras, the case became a test of integrity—balancing justice with compassion. For Marissa and Milo, it was about finding peace after years of living a lie. The show’s haunting message was clear: even love can lead to unforgivable choices.

All Her Fault closed on a bittersweet note, with Marissa and Milo walking toward a new beginning—free from Peter’s shadow but forever scarred by the truth that love, lies, and loss are all intertwined.
