A Shocking Sirens Ending That Sparks Debate Over Loyalty, Survival, and Sisterhood
Netflix’s Sirens wrapped its five-episode run with a finale that has fans buzzing, debating, and dissecting every choice made by its central characters.
As the show’s final scene fades out with Simone (Milly Alcock) standing at the edge of a cliff once occupied by her former mentor Michaela (Julianne Moore), the message is clear: power has shifted, and nothing is what it seems.
The Sirens ending delivers a blend of betrayal, survival instincts, and the bittersweet cost of freedom. The series, created by Molly Smith Metzler, pulls no punches in its final chapter, forcing viewers to confront the complexity of its flawed and fiercely human characters.
Simone’s Fate: From Assistant to Replacement
Throughout Sirens, Simone’s relationship with Michaela straddled the line between admiration and dependence.
When Simone was abruptly fired after Michaela saw a photo of Simone kissing Peter (Kevin Bacon), her world was flipped upside down.
But rather than return to her old life in Buffalo with sister Devon (Meghann Fahy), Simone doubled down — ultimately choosing to stay and become Peter’s new partner.
The image of Simone standing alone at the cliff’s edge where Michaela once stood isn’t just symbolic — it confirms that Simone has, in many ways, taken Michaela’s place. She may have once been a “broken little girl,” as Devon described, but in the Sirens ending, Simone claims agency over her life — even if that means stepping into morally gray territory.
Milly Alcock admitted the ending left her “really sad,” noting that while Simone’s choice might be seen as betrayal, it’s also deeply rooted in survival. “This is her golden ticket,” Alcock said. “She dropped out of law school. She has no money. She’d be starting from ground zero. She’s willing to fight tooth and nail to be there and to be safe.”
Devon’s Return Home: Growth Through Letting Go
While Simone chooses luxury and security, Devon takes a harder road: returning to Buffalo without her sister and without closure. Still reeling from the weight of caring for their father (Bill Camp) alone and managing her sobriety, Devon finally begins to make choices for herself.
She decides to move out, seeking healthier boundaries while still supporting her dad.
The Sirens ending doesn’t grant Devon a victory in the traditional sense — she doesn’t get her sister back, and she leaves the island more broken than when she arrived. Yet, it’s also a turning point. Devon confronts her trauma, accepts her limitations, and stops forcing her version of “saving” onto Simone.
Meghann Fahy reflected, “She’s sort of refusing to acknowledge her sister’s wants and needs. But I think it felt right. It felt true they would make those choices.”
Michaela and Peter: Power Dynamics and Gender Commentary
The power couple at the center of the island — Michaela and Peter Kell — face their own unraveling. After Peter leaves Michaela and aligns with Simone, the show leans into its central critique: why do women always bear the blame?
Nicole Kassell, who directed the first two episodes, pointed out that viewers might instinctively want to hate Simone, but the real question is: why aren’t we holding Peter accountable?
“Historically, we are conditioned to shit on the women who break up relationships,” Kassell said. “But Peter is targeting someone 40 years younger. It’s a tale as old as time.”
Michaela’s departure feels both tragic and empowering. She loses her husband and her assistant — but in the end, she and Devon share a moment of clarity, realizing that their perceived enemies weren’t each other, but the systems and people who used them.
Final Cliffside Scene: A Mona Lisa Smile and Open-Ended Meaning
The final moment — Simone alone on the cliff — is haunting. Her expression is unreadable. Is she triumphant? Trapped? Mourning? Metzler chose a take where Simone gives a Mona Lisa-like smile, leaving the interpretation up to the viewer.
The Sirens ending doesn’t provide easy answers. Instead, it invites empathy. What would you do if returning home meant confronting poverty, trauma, and no clear future? Would you stay in a world that finally sees your worth — even if it costs you your integrity?
Sirens Ending Asks More Than It Answers
Sirens may be just five episodes long, but its emotional impact and thematic weight linger. The Sirens ending captures the heart of what the show set out to explore: female agency, moral compromise, and the price of survival.
Metzler hopes the series sparks conversation, saying, “I can’t ask you to feel a certain way about what Simone does. All I can ask is that you try to understand it. What would you do?”
