Is Helen’s Baby Related to Juliette in Silo? The Pregnancy Theory Explained

Silo Season 3 Episode 9 finally confirms that Helen Drew (Jessica Henwick) is pregnant when the old world collapses, immediately giving viewers a new question to obsess over: is her child an ancestor of Juliette Nichols (Rebecca Ferguson)? The show has not confirmed that connection, and there are several generations separating Helen from Juliette, so calling the baby Juliette’s direct ancestor would be premature. Still, “Farewell” piles up enough circumstantial evidence to make the theory worth taking seriously. Helen is stranded near Silo 18, Daniel Keene (Ashley Zukerman) is separated from her at Silo 1, and the duck PEZ dispenser that once belonged to Helen eventually survives inside Juliette’s silo.

Full spoilers follow for Silo Season 3 Episode 9, “Farewell.” The identity and future descendants of Helen’s unborn child have not yet been confirmed by the series.

Is Helen’s baby related to Juliette in Silo?

Silo has not confirmed that Helen’s baby is related to Juliette, but Episode 9 deliberately creates several connections that make Juliette one of the most obvious candidates for a distant descendant. Helen’s pregnancy, her placement at Silo 18, and the PEZ dispenser all connect her family to the same underground community where Juliette lives centuries later.

The important word here is “distant.” Helen and Juliette are separated by hundreds of years, so the unborn child cannot simply be Juliette’s mother or grandmother despite some of the more enthusiastic theories circulating among viewers.

What the show could reveal is that Helen and Daniel begin a family line inside Silo 18 that eventually leads to Juliette. That would turn Season 3’s Before Times storyline from a historical explanation into something much more personal for the show’s main character.

There is also a neat storytelling reason to do it. Juliette has spent three seasons trying to reconstruct a history deliberately removed from Silo 18, while Helen spends Season 3 risking her life because she refuses to stop investigating that history before it even becomes forbidden.

Making them part of the same family line would be very tidy. Perhaps suspiciously tidy, but Silo has never been afraid of letting one little relic carry several centuries of dramatic weight.

When does Silo confirm that Helen is pregnant?

Episode 9 confirms Helen’s pregnancy after the Before Times storyline jumps forward and shows that she and Daniel have built a life together. They return for the completed silo project’s opening event with Helen visibly several months pregnant and apparently expecting the child with Daniel.

The development matters because Episode 8 had ended with Daniel and Helen rejecting Per Stensen’s attempt to pull them deeper into the silo project. They wanted out, only for “Farewell” to reveal that life has moved forward and the silos are now completed.

Their return does not mean they have suddenly embraced Stensen’s worldview. Daniel is surprised they were invited at all, which helps maintain the sense that the pair are visitors rather than willing members of the inner circle.

Pregnancy changes the stakes anyway. Helen and Daniel are no longer deciding only whether they personally would accept life underground, because every calculation now includes the survival of their child.

The timing becomes brutal when the nuclear explosion occurs. Helen is several months pregnant, Daniel is on the other side of the complex, and both suddenly have seconds rather than years to decide where their family will survive.

Why does Helen ending up at Silo 18 matter?

Helen ending up beside Silo 18 matters because it places her and her unborn child inside the exact community whose history Juliette spends centuries later trying to uncover. Daniel, meanwhile, is forced toward Silo 1, creating two separate family and political threads at the birth of the silo era.

Helen was originally attending a tour rather than preparing to become a permanent Silo 18 resident. Once the nuclear blast occurs, however, planned assignments and personal preferences become irrelevant. Daniel cannot reach Helen in time. She cannot cross the complex to him, and the nearest possible shelter is Silo 18.

If Helen survives the blast and gets inside, her baby would presumably be born among Silo 18’s earliest generation. That would immediately create the possibility that at least one present-day character descends from Helen and Daniel.

Juliette is an appealing candidate because of the parallels between the two women. Both are stubborn investigators who keep asking questions after authority figures make it abundantly clear that curiosity is hazardous to one’s health.

That personality similarity is not genetic evidence, obviously. It is, however, exactly the sort of character echo television writers like to build before revealing a family connection.

Does the PEZ dispenser prove Juliette is Helen’s descendant?

The PEZ dispenser does not prove that Juliette is Helen’s descendant, but it strongly suggests that Helen’s story becomes part of Silo 18’s hidden history. The relic creates a physical chain between Daniel and Helen’s relationship and Juliette’s present-day investigation.

Daniel originally gives Helen the duck-shaped PEZ dispenser during the Before Times storyline. Long after ordinary knowledge of their world has disappeared, a matching relic exists inside Silo 18 and eventually belongs to George Wilkins (Ferdinand Kingsley).

George’s PEZ later becomes central to Juliette’s own story. In Season 3, Robert Sims (Common) gives it back to her after Vitamin D+ has damaged her memories, and touching the object helps reconnect her to George, Silo 17, and the Safeguard. That makes the relic one of the show’s most deliberate bridges across time.

Episode 9 now places its original owner beside Silo 18 at the precise moment humanity goes underground. The simplest explanation is that Helen, or someone with her during the evacuation, carries the PEZ inside.

What the object does not tell us is who inherits it afterward. A relic can move between friends, families, smugglers, collectors, Flamekeepers, and generations without following a direct bloodline.

The PEZ proves a connection between Helen’s world and Juliette’s silo far more convincingly than it proves shared DNA. That distinction is worth keeping until the show gives us an actual family tree.

Could George be Helen and Daniel’s descendant instead of Juliette?

George could theoretically be a descendant of Helen and Daniel, and the PEZ dispenser gives that theory a different kind of logic. The relic is associated with George long before it becomes emotionally important to Juliette, so a family inheritance route through George cannot yet be ruled out.

George also shares Helen’s refusal to accept official explanations. His investigation of the silo’s history, the hidden door, relics, and the hard drive eventually sets Juliette on the path that transforms the entire series.

If the PEZ had been preserved within one family for generations, George possessing it would be meaningful. His connection to people who protected forbidden history could also fit with Helen becoming one of the earliest residents unwilling to accept memory suppression.

There is no direct evidence for this theory either. George could have acquired the relic through the illegal relic trade just as easily as through inheritance, and the show has already established that such objects circulate secretly.

Another possibility is that Helen’s descendants are people we have already met without the series making the connection obvious. Juliette, George, Allison, Walker, or even an entirely different family could eventually be tied back to her child.

The smartest thing “Farewell” does is make the pregnancy important without immediately telling us why. The finale now has an easy way to turn a historical storyline into a bloodline mystery without locking itself into the most obvious answer.

Why do viewers think Juliette is the most likely descendant?

Juliette is the most popular candidate because her personality, engineering instincts, connection to the PEZ, and position inside Silo 18 all create parallels with Daniel and Helen. None of those clues individually establishes ancestry, but together they make the theory easy to understand.

Helen contributes the investigative side of that equation. She is a journalist who cannot stop following uncomfortable questions, even when powerful people threaten her career and safety.

Daniel contributes the technical and political connection to the silo project. He understands the engineering behind the diggers and becomes increasingly entangled with the people constructing the underground network.

Juliette combines both tendencies. She is an engineer by profession but an investigator by temperament, which makes her feel like a character assembled from qualities the Before Times pair possess separately.

There is also a broader dramatic symmetry. Helen investigates how the silos are being created, while Juliette investigates why they exist and what their creators hid. One woman stands at the beginning of the lie and another at the end of it.

My read is that the show wants viewers to consider the connection, whether or not Juliette ultimately turns out to be Helen’s descendant. The repeated similarities are too useful as misdirection if nothing else, especially with one episode left in the season.

Could Helen’s child explain why Silo 18 keeps rebelling?

Helen’s child could theoretically become part of a family line associated with Silo 18’s repeated resistance, but Episode 9 does not establish any genetic reason for rebellion. The more grounded explanation is that Helen may carry knowledge into Silo 18 that the authorities later try to erase. That possibility is more interesting than the idea that rebelliousness simply passes through DNA.

Helen knows that the silos were constructed before the catastrophe. She knows Per Stensen, Daniel, Senator Thurman, the nanotechnology threat, and enough of the conspiracy to understand that Silo 18 was never merely an isolated shelter built by mysterious ancestors. If she survives inside Silo 18, that knowledge becomes dangerous almost immediately.

We already know the later system depends upon forgetting. Relics are banned, books disappear, history becomes inaccessible, and Vitamin D+ can suppress personal memory when the population becomes difficult to control.

A woman like Helen entering the first generation with direct knowledge of the outside world would be exactly the kind of resident that such a system eventually needs to silence.

Her child could inherit stories even if later generations lose the details. The PEZ itself may survive because someone understood that objects can preserve memory when official history cannot.

That offers a more compelling reason Helen’s family could matter to Juliette’s era. Their inheritance may not be a special gene but a habit of refusing to forget.

Does Helen and her baby survive the nuclear blast?

Episode 9 does not confirm whether Helen or her unborn baby survives the nuclear blast, although the final moments give her at least a possible route into Silo 18. A guide reaches Helen as the shockwave closes in, but the episode cuts away without showing her safely underground.

Jessica Henwick’s continuing involvement with Silo means Helen’s story is not finished from the audience’s perspective. That still should not be treated as confirmation of physical survival because the series is already comfortable moving between time periods.

The PEZ dispenser provides stronger story evidence than casting information. If Helen carries it into Silo 18, the show has a clean explanation for how Daniel’s gift survives hundreds of years and eventually reaches Juliette. Her pregnancy adds another unresolved connection.

As the nuclear cloud swallows the complex, Daniel runs toward Silo 1 while Helen is pulled toward Silo 18. The couple who uncovered the beginnings of the project are separated at the exact moment it becomes humanity’s new reality.

Whether Juliette carries Helen’s blood is still only a theory. What Episode 9 makes much harder to dispute is that Helen, her unborn child, and Silo 18 are now part of the same unfinished story.
