S1E1A Mechanical engineer with no law background is drawn toward the silo's secrets by George Wilkins.
S1E8Her mother Hanna took her own life after Judicial destroyed the unsanctioned magnifier she built - the wound that drove Juliette down to Mechanical.
S1E10Sent to clean, she refuses to wipe the lens, walks over the hill, and survives - proving the display is not the whole truth.
S2E3Reaches Silo 17 and meets Solo, its lone survivor. The silo is a flooded, decades-dead ruin.
S2E10Returns to Silo 18 amid a rebellion; the finale ends on an airlock/fire cliffhanger.
S3E3Resists the memory drug - spitting out her "vitamins" - and starts regaining pieces of herself, knocking on doors for Lukas. When Camille floods the mines with poison gas, Juliette gives up her mask to a miner, is struck down, and is saved by Lukas, who reveals himself. She ends the episode hospitalised again.
S3E4Camille sends Emerson to kill her, but Nurse Amy sedates him instead - and it emerges Amy had already been tapering Juliette's memory-suppressant. Cornered by Sims, Juliette is saved by Shirley and goes deeper into the silo, where she finds Bernard alive in the Digger Void. Her memories of George resurface - emotional identity returning, not just facts.
S3E5The amnesia arc pays off: Sims hands her the Pez dispenser and the rest of her memory floods back. She remembers that Silo 17 capped the Safeguard pipe and rushes to tell the others - back in active-protagonist mode, ready to restart the anti-Safeguard mission.
S3E6Full memory restored, she moves into strategy: she wants a team sent to Silo 17 to rescue its children and learn how Solo capped the Safeguard pipe. She offers Knox and Shirley first - and when the Voice rejects them and approves Lukas and Patrick, fans read it as Juliette baiting the Voice into her real choices. She pulls Camille somewhere "with no cameras," seeding a possible secret alliance against the Voice.
S3E7She sends Lukas and Kennedy out and lines up a reckless backup: if Silo 17 fails, blow open Judicial to expose the pipe system and cap the poison pipe before the silo dies - a plan that could kill huge numbers, marking her most desperate, ethically dark turn. When Kennedy's radio contact lands, she aborts the detonation seconds before it fires. Her real aim widens from rescuing children to extracting the Safeguard-pipe fix from Silo 17.
