Silo season 2 ending explained: Flashbacks, Juliette’s fate, and intriguing mysteries

The conclusion of Silo season 2 wraps up several ongoing storylines, but it also opens up new questions, especially with a captivating flashback. After facing numerous obstacles in her journey, Juliette finally has a breakthrough in the season finale. She not only assembles a makeshift firefighter suit but also manages to save her silo's inhabitants just in time before they leave.

However, the season ends on a cliffhanger, leaving viewers uncertain about the fate of Juliette and Bernard, who get trapped in the airlock of Silo 18. The show also hints at a shift in leadership within Silo 18, as the Algorithm designates Camille for an unknown role. The season finale of the Apple TV+ sci-fi show also includes a thrilling flashback that may set the stage for the origin story of the post-apocalyptic world in Silo season 3.

In Silo season 2, Bernard reveals that the silos were constructed 352 years ago, indicating that it has been more than three centuries since a catastrophic event forced humanity to seek refuge underground. Based on this, it's reasonable to assume that the flashback in the season finale, showing a meeting between Helen and the Congressman, takes place over 300 years before the current events of the show.

Helen, revealed to be a journalist with The Washington Post, seeks to understand the U.S. government's response to a suspected Iranian attack. The Congressman, portrayed by Donald Keene from the books, introduces himself as a representative from Georgia's 15th district. Initially thinking he's on a date with Helen, the Congressman eventually realizes her true intentions when she questions him about the "dirty bomb" attack in New Orleans. Though the Congressman seems to know more than he's letting on, he chooses not to share any details and leaves the conversation abruptly.

While the exchange between Helen and the Congressman doesn't directly explain the world’s fate or the origins of the silos, the flashback provides crucial clues. For example, before meeting Helen at the pub, a guard scans the Congressman for radiation, implying the U.S. is facing a radiological threat. He also holds a pamphlet featuring a hazmat suit and the words "The New Normal," suggesting his involvement in addressing the radiological event or in retaliating against a hostile nation.
