What happened in Silo Season 3 Episode 3?
Spoilers ahead for Silo Season 3 Episode 3.
Episode 3 places Camille Sims in control of IT after the Algorithm decides that her ability to manipulate people makes her suitable for the role. She learns that the system wants the memories of all 9,913 Silo residents erased unless she can stop the threat developing inside the structure.
Meanwhile, Juliette enters the mines with Knox as she continues looking for Lukas Kyle. Camille releases poison gas in an effort to force Lukas out, leaving Juliette close to death. Lukas eventually rescues her before a group of Outsiders takes him away.
The Algorithm later sees Juliette’s possible death as a way to calm the population. Camille reluctantly accepts an order to have her killed, placing Juliette in immediate danger heading into Episode 4.
What to expect from Silo Season 3 Episode 4
Episode 4 will likely focus on Camille’s assassination order and whether she follows the Algorithm’s instructions. Although Camille has repeatedly protected the Silo’s system, her decisions in Episode 3 show that she still questions its extreme methods.
Juliette may also begin investigating Lukas’ disappearance after recovering from the gas attack. The Outsiders who rescued Lukas appear to know more about the Silo, its surveillance system and the safeguard protocol. Finding them could give Juliette the information she needs to challenge the Algorithm.
Sheriff Paul Billings is also investigating a murder connected to the mines. His discovery that Kat Billings is an Outsider adds another personal conflict, especially as tensions between Silo residents and the hidden group continue to rise.
The “Before Times” storyline should move forward as Congressman Daniel Keene and journalist Helen Drew investigate the mysterious recording and the conspiracy surrounding the pilots. Season 3 uses two timelines to explain how the underground silos were created more than 350 years earlier.
How previous seasons led to Season 3
The first two seasons followed Juliette as she uncovered the truth about Silo 18 and learned that other silos existed nearby. Season 2 ended with Juliette returning home and becoming trapped with Bernard Holland as cleansing fire filled the airlock.
Season 3 begins with Juliette alive but suffering from memory loss. She now serves as mayor while Robert and Camille Sims use her condition to control the Silo. At the same time, the historical storyline explores the decisions that created the underground system and the catastrophe that forced humanity below the surface.
Silo Season 3 Episode 4 arrives on Apple TV on July 24. Will Camille carry out the Algorithm’s order, or will she help Juliette uncover the truth? Let us know what you think will happen in the comments.
