All Her Fault Finale Explained: Sarah Snook & Showrunner Break Down the Shocking Ending (2025)

Is the Nightmare Truly Over for Marissa? Sarah Snook and Showrunner Megan Gallagher Unpack the Shocking Finale of *All Her Fault*

Warning: Major spoilers ahead for the finale of Peacock’s All Her Fault. Proceed with caution if you haven’t caught up yet!

The gripping psychological thriller All Her Fault has left audiences reeling, not just from its heart-pounding plot twists but also from the profound societal questions it raises. But here’s where it gets controversial: Is this really the end, or could there be more to the story? Executive producer Nigel Marchant, known for Downton Abbey and The Day of the Jackal, saw the potential in Andrea Mara’s bestselling novel, which explores themes far beyond a child’s abduction. Adapted by Megan Gallagher, the series delves into the unequal distribution of domestic labor in marriages and the relentless scrutiny women face—topics that are as timely as they are divisive.

The Twists That Kept Us Guessing

What makes All Her Fault stand out is its intricate layering of suspense. Sarah Snook, fresh off her Emmy-winning role in Succession, anchors the series as Marissa, a woman whose seemingly perfect life unravels after her son Milo’s disappearance. Snook’s ability to navigate Marissa’s emotional labyrinth is nothing short of masterful, but it’s the reveal of Milo’s true identity—Josephine, the daughter of nanny Carrie (Sophia Lillis)—that leaves viewers stunned. And this is the part most people miss: the meticulous timing of these revelations, which Snook describes as a ‘dean of the details.’

The Unlikely Alliance That Defies Expectations

One of the most unexpected twists? The evolving friendship between Marissa and Jenny (Dakota Fanning), whose son Jacob was Milo’s playmate. Instead of descending into blame and bitterness, the two women find solace in each other, challenging the typical narrative of mothers at odds. Fanning notes, ‘We flipped that on its head and said, ‘No, these two are going to be friends, and they’re going to help each other through this.’ This unconventional bond raises a thought-provoking question: Can forgiveness and solidarity truly triumph in the face of unimaginable loss?

The Social Commentary That Hits Close to Home

Beneath the thriller’s surface lies a scathing critique of modern motherhood. Snook highlights the ‘invisible load’ women bear, often shouldering the mental and emotional labor in relationships. Gallagher adds, ‘Every woman I know between the ages of 30 and 55 is breaking down in tears outside the school gates, thinking, ‘How is it going to get done and how am I going to do it all?’ This raw portrayal of working mothers’ struggles is both relatable and unsettling, sparking conversations about fairness and equality in partnerships.

The Characters That Demand More Screen Time

From Detective Alcaras (Michael Peńa), a compassionate law enforcement officer caring for a special needs child, to the complex dynamics of Peter (Jake Lacy) and his siblings, each character feels ripe for further exploration. Gallagher admits, ‘We could write eight episodes about any character in this story.’ But is there room for a second season? While Marchant insists the series is ‘one and done,’ Snook teases lingering questions about Milo’s future and Marissa’s journey. Could there be more to uncover?

The Final Question: What’s Next?

As All Her Fault concludes its eight-episode run on Peacock, fans are left wondering: Is this truly the end, or is there more to Marissa’s story? And here’s where we invite you to weigh in: Do you think a second season is necessary, or does the series end perfectly as is? Share your thoughts in the comments—we’re eager to hear your take on this twisty, thought-provoking thriller.
