Daniel survived for centuries through repeated periods of cryogenic sleep and memory manipulation. He now lives under the name Troy and works inside Silo 1, where he helps control the other silos. His personality has also changed dramatically, which becomes clear when he authorizes the killing of thousands of people during the Silo 17 rebellion.
However, parts of Daniel’s original memories remain. Troy repeatedly sees flashes of a woman he cannot identify, suggesting that the memory treatment never completely erased his past.
Who is The Algorithm?
Another major reveal concerns The Algorithm, the mysterious authority that has been communicating with Camille Sims.
The person behind it is Dr. Victor Crnkovich, who was involved with memory suppression before the silos became humanity’s permanent home. Victor has remained part of the operation across the centuries and has been directing events inside Silo 18.
Camille eventually learns that Silo 1 plans to activate the Safeguard and kill everyone in Silo 18. She turns against the system and secretly helps Juliette’s allies block the pipe designed to release deadly gas.
That decision saves Silo 18, but Juliette knows their safety will only be temporary.
Why does Juliette want to attack Silo 1?
Juliette reaches the underground tunnel previously discovered by Lukas and communicates with Troy. He offers Silo 18 a deal: stop contacting other silos and Silo 1 will leave them alone.
Juliette appears to accept the offer, but she has already reached another conclusion. Rather than waiting for Silo 1 to attack again, she wants to use the underground tunnels to reach the command center and destroy its ability to control the silos.
Season 4 will therefore center heavily on the coming conflict between Juliette and Silo 1.
What does Victor’s final message to Troy mean?
The final scene gives Troy an important piece of his forgotten life.
Before dying, Victor records a message revealing that the woman Troy keeps seeing is Helen Drew, Daniel’s wife and the mother of his child. Troy breaks down as the name begins bringing those buried memories back.
The reveal also sets up another major Season 4 mystery: what happened to Helen after she entered Silo 18?
With Juliette preparing an attack on Silo 1 and Troy beginning to remember his old life, the final season now has its two biggest storylines moving toward each other. What do you think Juliette should do next, and can Troy eventually remember who he really is? Let us know in the comments.
