WARNING: SPOILERS AHEAD

How did season two end?

For those who need a little recap of how Silo season two ended, Juliette made a surprise return to the Silo, but as she re-entered she is met by Bernard, when they were both engulfed in a huge fire in the airlock.

Just as their fate was left hanging in the balance, the next scene showed a flashback to the Before Times in Washington DC in the darkness, and pouring rain. Congressman Daniel Keene (Ashley Zukerman) is seen arriving at a bar, where he has his radiation levels checked by a doorman, before sitting down and chatting to a journalist Helen Drew (played by Jessica Henwick).

Congressman Daniel thinks they're meeting for a date, but it's soon apparent that Helen has a different agenda, as she asks him about the dirty bomb that was detonated on US soil, and if America will retaliate. Daniel also gives Helen a Pez - which Silo fans will know has had significance throughout the series.

Here we take a look back at each of the season three episodes so far...

Episode one - 'Who Are You?'

As fans are left wondering if Juliette is going to survive the huge fire at the end of the second season, viewers' questions are put to rest in the opening scene of episode one.

Set three months after the rebellion, Juliette, now mayor, is suffering from amnesia and helped by someone in her apartment, who reminds her: "The Silo is at peace because of you, because you came back". Juliette then meets with Camille where she finds herself having to make an appearance in the cafeteria, surrounded by the members of the Silo. And that's all before the titles roll.

For the first time in the entire series we get a proper insight into the Before Times. Congressman Daniel Keene meets up with his sister, Charlotte 'Charles' Keene (pictured below) who is a US Navy pilot. The pair discuss Daniel's failed 'date', with Charles telling her brother to get onto Senator Rosalind Thurman's committee for military action against Iran.

Back in the Silo, Juliette is beginning to ask questions about how she survived the fire, and Bernard didn't, however the answers she is getting from Robert Sims are not the truth. She also meets up with Shirley hoping for some answers, but Shirley cages up and doesn't give any.

Meanwhile, back in the Before Times, Charles is sent to Iran to retaliate against the dirty bomb they dropped in the US, leaving her brother, the Congressman, concerned for her safety. Charles' plane crashes and the Navy pilot ends up at a special hospital being treated for her injuries including amnesia, where she's visited by her brother, but sadly she doesn't recognise him.

The episode ends with Juliette receiving a bowl of soup, which contains a note in a capsule. The note says: 'Want to know the truth? Leave your bowl upside down. Go to the marketplace at 2. BURN THIS!'

Episode two - 'It's All Good'

Despite the note saying to burn it, Camille knocks on the door forcing Juliette to stop. Suspecting something, Camille asks why she can smell smoke, but Juilette fobs her off saying she reheated some pizza. However, when Camille later goes to The Algorithm, 'he' tells her about the note.

Meanwhile, in the Before Times, Congressman Daniel spends time with his sister in hospital, hoping to bring back some of her memories by talking about their childhood, and their parents who passed away when they were young.

After meeting Charlotte’s ‘doctor’, Victor Crnokovich, he tells Daniel: “I’m afraid to tell you that I’m the reason she doesn’t remember you.” The pair then discuss her treatment, where Victor explains that she’s being given medication to stop her remembering, and they will decide when to stop the medication, and which memories they’ll bring back.

Daniel later bumps into his ‘date’ Helen telling her inadvertently which hospital Charlotte has been moved to, leaving it open for Helen to pay her an expected visit.

Back in the Silo, Orla Kent (the Shadow to the Head of Supply) has gone missing, after she spoke at the first Silo council meeting. Her sister arrives at the Sheriff’s office demanding him to follow-up on the missing person’s report.

Juliette starts to have flashbacks and decides to do what the note says, hoping to find out more answers. She makes a quick get away from her security, ending up in a room with the fugitives, Patrick Kennedy, Danny, and Sandy. Juliette is told that the helmet she was wearing was not from Silo 18 (The Silo), but another called Silo 17, and that the sign she held up outside was not her handwriting.

In the Before Times, Helen arrives at the hospital to chat to Charlotte, taking her for a walk, but Charlotte begins to have a seizure. When Daniel arrives and finds Helen there they begin to argue, before Helen reveals that she was asked by Charlotte to find out more about the Iran mission.

Season three episode three will arrive on Friday 17th July 2026.
