SIRENS Season 2 Release Date Confirmed: Milly Alcock’s Simone Is Pregnant—But Who’s the Father? Fans Are Betting on Three Men!

Netflix’s Sirens became a global sensation with its May 22, 2025, debut, blending dark comedy, sharp social commentary, and a gripping tale of sisterhood and betrayal. The five-episode first season, created by Molly Smith Metzler and based on her play Elemeno Pea, drew 16.7 million views in just four days, fueled by its stellar cast—Julianne Moore, Meghann Fahy, Milly Alcock, and Kevin Bacon—and its addictive narrative. After months of anticipation, Netflix announced on November 10, 2025, that Sirens Season 2 will premiere on August 14, 2026. The recently released trailer, dropped on November 15, 2025, has sent fans into a frenzy with a bombshell revelation: Simone DeWitt (Milly Alcock) is pregnant. The burning question—who’s the father?—has sparked wild speculation, with fans on X and Reddit betting on three different men. Let’s break down the announcement, dissect the trailer, and explore the theories driving this paternity mystery.

Season 2 Renewal and Release Date

Initially billed as a limited series, Sirens captivated audiences with its story of Devon DeWitt (Meghann Fahy) attempting to “rescue” her younger sister Simone from the clutches of billionaire socialite Michaela “Kiki” Kell (Julianne Moore) during a chaotic Labor Day weekend at Cliff House. The Season 1 finale, where Simone betrayed Michaela to become the new “Mrs. Kell” alongside Peter Kell (Kevin Bacon), left fans reeling and clamoring for more. Netflix’s surprise renewal for a six-episode second season, confirmed on November 10, 2025, reflects the show’s massive popularity and storytelling potential. Showrunner Metzler told Variety, “Simone’s choices open up a whole new world of conflict. We’re diving deeper into her psyche.” Filming began in early 2026 in New York, with locations like Caumsett State Historic Park set to recapture Port Haven’s opulent vibe.

The August 14, 2026, release date was announced alongside a 90-second trailer that has already racked up 6 million views on Netflix’s YouTube channel. The trailer picks up six months after Season 1, with Simone entrenched as the head of the Folger Wildlife Preservation Society and Peter’s partner, while Devon rebuilds her life in Buffalo. Michaela, now exiled to Manhattan, plots her revenge. But the trailer’s biggest shock comes at the 1:08 mark: Simone, visibly shaken, clutches her stomach in a lavish Cliff House bathroom, a pregnancy test showing two pink lines. A voiceover whispers, “Some secrets change everything.” Fans are losing it, and the paternity question has ignited a firestorm of theories.

The Pregnancy Bombshell: Simone’s New Arc

Simone’s pregnancy is a game-changer for Sirens Season 2. In Season 1, her decision to stay with Peter was driven by a desire for security, escaping a traumatic childhood marked by her mother’s suicide and her father’s neglect. Now, as “Mrs. Kell,” she’s navigating a precarious new role, with Peter’s infidelity and Michaela’s scheming threatening her stability. The trailer shows Simone grappling with her choice, her expression a mix of fear and determination as she hides the pregnancy test. Alcock, in a Vogue interview, teased, “Simone’s world is unraveling. This pregnancy forces her to confront who she’s become.”

The pregnancy raises stakes for Simone’s relationship with Devon, who’s back in Buffalo caring for their ailing father, Bruce (Bill Camp). The trailer hints at tension, with Devon saying, “You can’t keep running from who you are,” while Simone snaps, “You don’t get to decide that anymore.” Fans speculate the pregnancy could either mend their fractured bond or drive a permanent wedge, especially if Simone’s secrecy hurts Devon.

Who’s the Father? Fans’ Top Three Suspects

The trailer offers no clear answer on the father’s identity, but fans have zeroed in on three men based on Season 1 dynamics and subtle trailer clues. Here’s the breakdown:

Peter Kell (Kevin Bacon)
The most obvious candidate is Peter, Simone’s new husband and the manipulative patriarch of the Kell empire. Their marriage, cemented in the Season 1 finale, positions him as the likely father. The trailer shows a tense dinner scene where Peter grips Simone’s hand, his smile strained, suggesting he’s unaware of the pregnancy. Fans on X argue Peter’s controlling nature makes him a frontrunner, with one post reading, “Simone’s locked in with Peter—bet it’s his kid, but he’s gonna flip when he finds out.” However, Peter’s history of infidelity and his cold demeanor in the trailer raise doubts. Some theorize Simone might hide the pregnancy to maintain her grip on the Kell fortune, especially if Peter’s not the father.

Ethan Corbin (Glenn Howerton)
Ethan, the smarmy lawyer who survived his Season 1 cliff fall, is a dark-horse candidate. The trailer reveals his return, showing him whispering to Simone in a shadowy Cliff House hallway: “You owe me.” Their Season 1 flirtations, though brief, hinted at chemistry, and fans speculate a secret affair could have occurred during the six-month time jump. A Reddit thread posits, “Ethan’s got dirt on Simone from Season 1. Maybe they hooked up to seal an alliance against Michaela.” His survival and cryptic trailer role make him a compelling suspect, though his volatile personality suggests a dangerous fallout if he’s involved.

The Mystery Yacht Captain (New Character)
The trailer introduces a charismatic yacht captain, played by a yet-to-be-named actor, who appears in a scene flirting with Simone at a Port Haven gala. His charming smile and a lingering shot of Simone laughing with him have fans buzzing. One X post read, “New guy alert! That yacht captain’s giving major baby daddy vibes.” The captain’s outsider status makes him an intriguing wildcard, potentially offering Simone an escape from the Kell world. However, his limited screen time in the trailer leaves this theory speculative, with some fans arguing he’s a red herring.

Why the Paternity Mystery Matters

The question of the father ties into Sirens’ core themes of power, loyalty, and identity. Simone’s pregnancy could lock her deeper into the Kell family’s toxic web or push her to break free, depending on who the father is. If it’s Peter, she faces the challenge of raising a child in a dysfunctional dynasty. If it’s Ethan, the pregnancy could expose a dangerous secret, risking Michaela’s wrath. If it’s the yacht captain, it might signal Simone’s rebellion against her Season 1 choices. Metzler told Glamour, “Season 2 is about consequences. Simone’s pregnancy is a catalyst for everything to implode.”

Fans also see parallels to the show’s mythological roots. The title Sirens evokes Greek mythology’s seductive, destructive figures, and Simone’s pregnancy could symbolize a new “siren” entering the world, complicating her arc. A fan on Reddit wrote, “The baby’s a metaphor for Simone’s choices—she’s creating something new, but it might destroy her.”

What Else to Expect in Season 2

Beyond the pregnancy drama, Season 2 promises a darker, more expansive story. Michaela’s return as a vengeful villain, teased in the trailer with occult-like imagery, suggests she’s plotting to reclaim her throne. Devon’s arc in Buffalo, including a potential new romance, sets up a contrast with Simone’s gilded cage. New characters, like a journalist probing the Kells, will add fresh conflicts, while Port Haven’s elite society remains a hotbed of intrigue. The six-episode arc allows for deeper exploration of the DeWitt sisters’ bond and the fallout of their Season 1 betrayals.

Fan Frenzy and Final Thoughts

The Sirens Season 2 trailer has unleashed a wave of excitement, with Simone’s pregnancy and the paternity mystery dominating discussions. On X, posts like “Simone’s pregnant?! Peter, Ethan, or yacht guy—place your bets!” and “Milly Alcock’s about to serve DRAMA” reflect the hype. Reddit threads are dissecting every trailer frame, from Simone’s nervous glances to the men’s subtle interactions. The August 14, 2026, premiere can’t come soon enough for fans eager to see how this twist unfolds.

Sirens Season 2 is poised to deliver another addictive chapter, with Milly Alcock’s Simone at the heart of a high-stakes mystery. Whether the father is Peter, Ethan, or the enigmatic yacht captain, the pregnancy promises to upend Simone’s world, challenging her loyalties and ambitions. With its sharp writing, stellar cast, and a trailer that’s already breaking the internet, Sirens is set to keep viewers hooked, proving once again why it’s one of Netflix’s boldest hits.
