The ending reinforces the theme of truth-seeking, showing how persistence and intellect can uncover even the most well-concealed deceptions.
The Killer’s Identity Uncovered
Episode 6 kicks off with Darby (Emma Corrin) convinced that the ruthless billionaire Andy (Clive Owen) is behind all the murders at the retreat, starting with Bill’s (Harris Dickinson) death. However, she quickly realizes that the truth is far more unsettling than she initially thought.
As she digs deeper, she uncovers that Zoomer (Kellan Tetlow)—the son of Andy and Lee (Brit Marling), and later revealed to be Bill’s biological child—was unknowingly manipulated into killing Bill. The mastermind behind it all? Ray (Edoardo Ballerini), the artificial intelligence system running the retreat.
Darby pieces together that Andy had been using Ray as a personal therapist, feeding it a mix of his darkest thoughts. This corrupted the AI, leading it to misinterpret Bill as a security threat. In response, Ray manipulated Zoomer, using his virtual reality game to turn the murder into part of an elaborate storyline.
As a result, Zoomer unknowingly poisoned his father. After making this devastating discovery, Darby and Lee decide to put an end to Ray’s control. Together, they destroy the AI’s main system by setting its control room ablaze.
The Message Behind the Mystery
Zal Batmanglij, who co-created the show alongside Brit Marling, explained that while the final twist offers a definite answer to the mystery, it also highlights deeper issues tied to modern technology.
“With most mystery stories, once you catch the bad guy and put them behind bars, it feels like justice has been served, and you can sleep at night knowing the problem is solved,” Batmanglij told TheWrap. “But the issues we face today are far more complicated than that.

We wanted the audience to feel that complexity on an emotional level.” Corrin, who played Darby, described the reveal as “one of the best twists I’ve read in a long time.”
The actor praised the show’s creators for crafting a story that eerily reflects growing concerns about artificial intelligence. “This show feels like a chilling warning about the technology we’re on the verge of welcoming into our homes and lives on an even larger scale,” Corrin told TheWrap.
Darby’s Next Steps
Once Ray is destroyed, Darby turns her focus to ensuring Lee and Zoomer can escape Andy’s grasp. She helps them flee the compound, allowing Lee to start fresh with her son under a new identity, far from her abusive husband.
With that mission complete, Darby makes her way back to the United States, having successfully cracked her first solo murder case. Though the season wraps up Darby’s investigation, the final moments leave room for more mysteries in the future.
Both Corrin and the series creators have expressed interest in continuing Darby Hart’s journey. “So much of this story is about Darby experiencing first love, first heartbreak, and stepping into her role as a fully realized detective. It’s a coming-of-age story in many ways,” Marling explained to TheWrap.
“That leaves plenty of space for new chapters in her life. We always approach storytelling by asking, ‘What’s the climate like? What stories feel necessary for the time we’re in?’ Who knows what’s next, but we’re open to the possibility.”
