When the latest episode of the critically acclaimed fantasy drama dropped, viewers were hit with a twist no one saw coming: Simone, portrayed by the ever-enigmatic Milly Alcock, was seen cradling a visibly pregnant belly. No dialogue. No flashbacks. Just a quiet, emotionally loaded moment that sent shockwaves through the fanbase.

Now the fandom is ablaze with speculation, and social media is flooded with theories. The big question on everyone’s mind?

Who is the father of Simone’s child?

Let’s dive in.

A Quiet Bombshell: The Pregnancy Reveal

The episode had been building toward something, but few could have predicted this. Simone, previously depicted as fiercely independent and emotionally guarded, appears in the final scene standing at the edge of the coast, gazing out into the mist. Her silhouette in the moonlight makes it impossible to ignore — she’s pregnant.

The show offers no hints in dialogue or exposition, and the creators have remained silent on the reveal. But in SIRENS, silence speaks volumes.

This single scene has opened the floodgates for interpretation, and fans have honed in on three potential fathers, each bringing a different emotional — and possibly supernatural — implication.

Contender #1: Kael, the Human-Siren Hybrid

Kael, played by Tom Blyth, has long been a fan favorite — the brooding, morally ambiguous hybrid who struggles between two worlds. His connection with Simone has been fraught with tension since Season 1, marked by unspoken longing, trust issues, and explosive confrontations.

In Season 2, their interactions deepened, most notably in episode 4, where the two shared an emotionally charged night after surviving a near-death ambush. While the show never confirmed if that encounter turned romantic, fans were quick to note lingering glances and cryptic dialogue like Kael’s: “Some scars heal in ways you don’t expect.”

Kael as the father opens up dramatic possibilities. A child born of a siren and a hybrid? The implications could redefine the show’s entire mythology.

Contender #2: Elias, the Mysterious Stranger

Elias is the wildcard — a character who appeared only in Season 2, episode 2, washing ashore in the middle of a storm. Played by newcomer Malik Zaire, Elias claims to have no memory of who he is or how he got to the island. Yet, he seems to possess an innate understanding of the sea and Simone in particular.

In episode 5, Elias and Simone share an intense, dreamlike sequence in the underwater ruins of Caelum, the long-lost siren capital. There’s a strange intimacy between them, one that borders on the mystical. Some fans speculate Elias is not just another stranger, but perhaps a siren god in disguise.

If Elias is the father, the stakes escalate beyond politics and romance. We’re talking divine bloodlines, ancient prophecy, and Simone as the unwitting vessel of destiny.

Contender #3: Rowan, the Exiled Prince

Then there’s Rowan.

He’s the character everyone loves to hate — Simone’s childhood friend turned rival, turned maybe-lover? Their relationship is a labyrinth of betrayal, unresolved feelings, and power plays. But in Season 2, Rowan (played with delicious menace by Alex Fitzalan) softened in ways that caught Simone — and viewers — off guard.

Episode 6 featured an emotionally raw scene between the two, alone in the ruins of the old lighthouse. There were confessions. Tears. A kiss. The next morning, Simone was gone.

If Rowan is the father, the narrative becomes Shakespearean: a child born of enemies, forced into alliance. It’s the kind of drama SIRENS excels at.

Fan Theories Are Spiraling Out of Control

Naturally, the fandom isn’t sitting idle. Theories are flying across Reddit, TikTok, and Twitter (or rather, X), ranging from the plausible to the outlandish.

Some believe Simone isn’t pregnant at all, but undergoing a ritual transformation unique to her bloodline. Others are convinced the pregnancy is a vision — a metaphor for her internal struggle or a prophecy yet to be fulfilled.

A popular crack theory suggests the baby is not Simone’s, but that she’s acting as a surrogate for the Sea Mother — a sentient oceanic force hinted at in Season 1.

Another camp of theorists believes this is all part of a larger political plot: Simone’s pregnancy could be used as leverage in the brewing war between the sirens and the surface dwellers. Could she be a pawn? Or the queenmaker?

Why This Twist Works

One of SIRENS’ greatest strengths is its ability to surprise without betraying its own logic. Simone’s pregnancy may be shocking, but it doesn’t come out of nowhere. Season 2 has been quietly laying the groundwork: the themes of legacy, identity, and transformation have been threaded through every subplot.

Simone herself has always been a cipher — emotionally layered, morally complex, and fiercely loyal. To place her at the center of a mystery with such biological, political, and possibly spiritual weight only enriches her arc.

Plus, Milly Alcock delivers a subtle, devastating performance in the reveal scene. Her expression — a mix of fear, wonder, and quiet defiance — tells us everything we need to know. Simone didn’t ask for this. But she’s ready to face it.

What This Means for the Rest of the Season

With just four episodes left in the season, fans are expecting answers — and soon. Will the show continue to tease, or will it deliver a clear reveal?

Here’s what we might expect:

Episode 7: Flashbacks to Simone’s time away between seasons — a gap in her timeline that has never been fully explained.

Episode 8: A confrontation between Simone and Rowan that shakes alliances and unveils hidden motivations.

Episode 9: A new threat rises — possibly connected to the child.

Episode 10 (Finale): The child’s father is revealed in a devastating twist, setting up a shocking cliffhanger for Season 3.

Of course, SIRENS has never been predictable. That’s part of its magic.

Final Thoughts: The Ocean Is Hiding Secrets

Simone’s pregnancy is more than a twist. It’s a narrative earthquake that reframes the stakes, challenges character loyalties, and opens up vast new storytelling terrain.

Whether the father is Kael, Elias, Rowan — or someone (or something) else entirely — one thing is certain: SIRENS is doubling down on what it does best. Emotional stakes. Mythological mystery. And moments that spark online obsessions.

As the waves crash harder and the plot thickens, fans will be watching every frame, analyzing every glance, and speculating right up until the season finale.

Until then, we wait. And we wonder.

Who’s the father? What’s the child’s destiny? And what is Simone hiding still?

One thing’s for sure — this is no ordinary pregnancy. And the truth will change everything.
