A dark-haired woman in a bright red jumper holds a phone to her ear on open grassy ground as a flash lights the far horizon and a towering wall of dust rolls toward her.
The opening of the silos near Atlanta: Helen Drew, on the phone to Daniel Keene, sees the flash and the dust coming. She was touring Silo 18, and is pulled underground; what became of her is held back.

Silo, season 3

Ten episodes from Shift, more or less: a mayor who has forgotten everything, and a Washington about to end.

Season 3 of Silo premiered on Friday, July 3, 2026, one episode at a time, and ran weekly to its finale on September 4: ten more episodes run by Graham Yost, the third of four. Yost calls it the Shift season, but Shift is a hard book to build around the series’ star: “Juliette doesn’t appear until like the last page, right?” So the season runs on two tracks. In Silo 18, three months after the uprising, Juliette is mayor and remembers nothing, and the story is a thriller about drugs and memory with a murder underneath. In Washington, in what Apple called the “Before Times”, Congressman Daniel Keene and the journalist Helen Drew chase a conspiracy to the end of the world.

That Washington is Shift’s opening moved into our own time: not the book’s 2049 but, in Yost’s words, “basically contemporaneous with us, give or take five years in the future.” Its people are renamed and rebuilt. Donald Keene is Daniel; his wife Helen is a reporter he has only just met; Senator Paul Thurman is Senator Rosalind Thurman; Charlotte flies for the Navy; and an invented trillionaire, Per Stensen, pays for the silos. The thread ends when the silos are sealed, and jumps once, in the finale, to Silo 1, where Daniel wakes as Troy. Much of the Silo 18 half is the series’ own, with pieces of Dust worked in.

Each episode below says what it draws from the books and what the series changed or invented. The frames paint the series’ version of each moment (a sunlit Washington, brighter by design, against a silo as dim as ever) in the walk’s own charcoal; they show characters, never performers.

Episode 1

Who Are You?

Silo 18 is calm, and Juliette is its mayor. She cannot remember the last months, her cleaning, or that other silos exist: Camille Sims, now head of IT, has been feeding her “vitamins” on the orders of the voice in the vault, which the recaps call the Algorithm. A flashback shows Bernard surviving the airlock fire too, and Robert Sims seemingly finishing him off. Patrick Kennedy is missing, and the Outsiders hang a banner saying it is nice outside. Then Juliette’s cook sends up soup with a note in a capsule: turn the bowl over, burn the note, go to the market. In Washington, the Navy pilot Charlotte “Charles” Keene urges her brother Daniel onto Senator Rosalind Thurman’s Iran committee as the United States strikes back for a supposed dirty bomb. Over a mountain facility in Iran, a strange cloud swallows her squadron. She is the only survivor, and does not know her brother.

From the books: Wool’s Juliette becomes mayor with her memory intact; Yost says “the only way Juliette could stay alive is if her memory was wiped.” Shift’s Washington begins with a freshman congressman from Georgia summoned by Senator Paul Thurman, whose daughter is Anna. The Iran war, the cloud and a woman senator are the series’; Shift’s Charlotte flies drones for the Air Force.

A fair-haired woman with tattooed forearms sits alone at a table in a spare concrete room, holding a tiny capsule of paper found in her bowl of soup.
S3 · 1 Soup for the Mayor Juliette is mayor of Silo 18 and cannot remember why. Camille Sims, on the orders of the voice in the vault, has been dosing her with “vitamins”, and the silo she governs is calm. Then her cook sends up chowder with a note hidden in a capsule: turn the bowl over, burn the note, go to the market. It is her first free choice in months. Wool makes Juliette mayor too, with her memory intact.
A fighter pilot in a helmet looks up in alarm as thick black ooze spreads across the inside of her cockpit canopy, other jets vanishing into a strange cloud over mountains.
S3 · 2 Into the Cloud The United States is striking back at Iran for a supposed dirty bomb in Washington, and the Navy pilot Charlotte Keene flies with the squadron sent against a mountain facility. A strange cloud swallows the jets, black goo seeps into the cockpits, and the planes go down. She is the only survivor, and wakes in a clinic not knowing her brother. Shift’s Charlotte flies drones for the Air Force; the war and the goo are the series’.
Episode 2

It’s All Good

The note was no secret: the vault watches Juliette’s rooms. Orla Kent of Supply misses a check-in, and Sheriff Billings starts looking. At the market a disguised Sandy leads Juliette to the Outsiders, Patrick and Danny, who believe the truth of what she saw outside is being hidden; Patrick guesses she is drugged, and Knox tells her about Lukas, missing, who may have answers. She stops taking her pills, and the Algorithm plans to put the “vitamins” in the main water supply: a memory reset of the whole silo. In Washington, Dr. Victor Crnkovich offers Daniel a drug that works as a “drawbridge” to Charlotte’s memory, and suggests he choose what to give back. A journalist, Helen Drew, is caught sneaking in to question Charlotte, who had fed her doubts before the mission, and asks Daniel to help her find the truth.

From the books: Shift’s Victor is the psychiatrist who doles out Silo 1’s pills of forgetting, and Shift’s Silo 18 is reset rather than killed, its memories wiped. The Outsiders and Orla are the series’; so is Helen as a reporter who comes to Daniel through his sister. In the book she is his wife.

A grey-haired doctor in a white coat talks quietly to a man in a navy suit beside a fair-haired woman who sits looking past them in a bright clinic room.
S3 · 3 A Drawbridge to Memory Daniel tells Charlotte their family history, and nothing comes back. Dr. Victor Crnkovich, who treats veterans free, describes a drug that works like a drawbridge to memory, and suggests Daniel choose which memories to give her. Once she calls him “Donald” by mistake, the series’ nod to the book. Shift’s Victor is the psychiatrist who doles out Silo 1’s pills of forgetting; this one begins by offering memories back.
Episode 3

A Dark Web

Off her pills, Juliette slips away to find Lukas, and Camille lets her go. Guessing that Lukas is in the mines digging toward another silo, Camille has them fumigated as rat control. Juliette and the miners are caught in the smoke; Lukas pulls her out and vanishes into the dark, and Billings identifies Orla among the dead. The vault suggests letting Juliette die, a martyr to keep the peace. In Washington, Daniel learns that the squadron was ordered onto old radios, and Helen is fired. They trade Daniel’s congressional badge to a dark-web hacker for twenty seconds of the pilots’ last chatter on a cassette; when they come back for a copy, his warehouse has been ransacked.

From the books: digging toward another silo is Dust’s, but there Juliette digs from Mechanical with a buried machine. The gassing, the martyr plan, the hacker and the tape are the series’.

In a smoke-filled mine tunnel, a grimy man with a cloth hood pushed back drags a half-conscious woman away through the haze by lamplight.
S3 · 4 Smoke in the Mines Camille has guessed where Lukas is: in the mines, digging toward another silo. She has them fumigated as rat control, and the miners and Juliette, who came down looking for him, are caught in the smoke. Lukas pulls her out and vanishes into the dark. Afterwards the vault suggests letting her die, a martyr to keep the peace. In Dust the dig to Silo 17 is Juliette’s own, from Mechanical, with a buried digging machine.
A man in a suit and a dark-haired woman lean close over an old cassette player in a cluttered warehouse while a third figure sits in the glow of monitors behind them.
S3 · 5 Twenty Seconds of Tape At a memorial for a pilot, Daniel learns that the squadron was ordered onto old radios, and that the military holds their last words. Helen, just fired over her Iran story, takes him to a dark-web hacker who has twenty stolen seconds of those words on a cassette. The price is Daniel’s congressional badge. When they come back for a copy, the warehouse has been ransacked. In Washington Shift’s Donald asks no such questions.
Episode 4

Whatever You Do, Don’t Go Home

Camille decides Juliette must die. Nurse Amy, who has been quietly lowering the dose, gets her out through a hidden passage, and Shirley takes her down to the Digger Void, the hideaway she shared with George. There, burned across the face and alive, is Bernard. Orla, it turns out, was murdered and dumped in the mines. In Washington the hacker is gone, and a fixer, Henry, leans on Daniel and Helen to stop, with bribes dressed as favours: a job at the New York Times for her, proper care for Charlotte. Helen wavers, Daniel refuses, and they part, until a call from his Pentagon friend Sam Ramsey sends him back to her. Hugh Howey called it “one of the most brilliantly shot, acted, directed, written episodes of the entire show.”

From the books: none of the intrigue; in Washington Shift’s Donald investigates nothing, and is recruited to design the silos. Wool’s Bernard dies in the airlock fire. “In the books, Bernard dies,” Yost said. “We thought, ‘No.’”

In a dark cavern beneath the rusted legs of a giant machine, a woman with a lamp stops short before a tall grey-haired man with burn scars on his face, sitting up on a camp bed.
S3 · 6 Bernard Alive Camille has decided Juliette must die, and nurse Amy, who has been quietly lowering her dose, gets her out through a hidden passage. Shirley takes her down to the Digger Void, the hideaway she shared with George, and there, burned across the face and very much alive, is Bernard. “In the books, Bernard dies,” Yost said. “We thought, ‘No.’” In Wool he burns in the airlock, sent out in Lukas’s place.
Episode 5

Memory

A flashback to the end of season 2: Knox, Shirley, Hank and Billings break into the burning airlock, and Juliette is winched down the stairwell on a door while every landing watches. In Medical, Sims holds a plastic bag over Bernard’s head, then cuts a hole in it, and Bernard tells him about the Safeguard. Sims hides Bernard below and has the silo talk Juliette up for mayor, so that she will be too beloved to kill; Bernard teaches Walker that Silo 1 can trigger the Safeguard in every silo. Relics stir only fragments in Juliette until, climbing back up, Sims gives her George’s PEZ dispenser, and it all comes back. In Washington, Sam’s tip names Per Stensen, a champion of AI control mixed up in the Iran mission, and on the way to meet a source Daniel’s car takes the wheel.

From the books: Shift’s Order, the founders’ manual, was written by Victor; fifty silos, and one that can kill the rest, are the books’ system. Sims’s change of sides is the series’. Per Stensen has no counterpart: the books’ founders are Thurman, Victor and the engineer Erskine.

A woman lying on a door is lowered on ropes down the open shaft of a vast spiral stair while people lean over the rails of the landings to watch.
S3 · 7 Out of the Fire The episode goes back to the end of season 2. Fire fills the sealed airlock, and Knox, Shirley, Hank, Billings and others break in and smother it. Juliette is laid on a door and winched down the stairwell to Medical while people on every landing watch. Bernard comes through too, and in Medical Sims holds a plastic bag over his head, then cuts a hole in it. In Wool the fire kills Bernard, and Juliette comes through badly burned.
On a dim landing of a vast concrete stair, a broad man in a leather jacket presses a small toy candy dispenser into the hand of a fair-haired woman.
S3 · 8 The PEZ Dispenser Sims has played his wife’s enforcer while hiding Bernard and making Juliette too beloved to kill. The relics he and the others bring her, a page from the nature book and George’s watch, stir only fragments. Climbing back up, he breaks down and gives back George’s PEZ dispenser, which he kept as a comfort. The dam breaks. It is the same duck Daniel Keene gave Helen Drew in Washington, the one object that crosses both timelines.
Episode 6

The Drive

Juliette comes to the rebels remembering everything, with a plan: Silo 17 blocked its Safeguard pipe, and since the silos are identical, 17’s plans can show where 18’s runs. She surrenders and bargains with the vault to send someone to 17. Knox and Shirley: “Request denied.” Lukas and Patrick, whom the Algorithm wants dead, are approved in seconds, and Camille has already put the drug in the water. In Washington the driverless car carries Daniel and Helen toward nowhere, and Helen confesses she lost her job taking the blame to protect a source. Police surround the car only to escort it, led by Henry, to a private hangar, where Senator Thurman asks if they want to help save the world.

From the books: that every silo is built alike, and that Silo 1 can gas any of them, are the books’ premises. The bargain and the car are the series’.

A fair-haired woman stands facing a large glowing monitor in a clean steel vault while a dark-haired woman in tailored dark clothes watches from one side.
S3 · 9 Request Denied Juliette has a plan: Silo 17 blocked its Safeguard pipe, and since the silos are identical, 17’s plans can show where 18’s runs. She surrenders and bargains with the voice in the vault to send someone there. Knox and Shirley: “Request denied.” Lukas and Patrick, whom the voice wants dead, are approved in seconds. Camille has already put the drug in the water. Silo 1’s power to gas any silo it likes is the books’.
At night a man in shirtsleeves sits in the driver’s seat of a speeding car, hands lifted off the wheel as it turns by itself, a dark-haired woman watching from the back seat.
S3 · 10 The Drive Daniel was driving to meet a source who could tell him about Per Stensen, a champion of AI control mixed up in the Iran mission, when his car swerved and took over. Now it carries them both toward nowhere. In the back seat Helen confesses she lost her job by taking the blame to protect a source. Police surround the car only to escort it, to a private hangar where Senator Thurman asks if they want to help save the world.
Episode 7

Radio

Juliette sends Lukas and Patrick out early, at night. Over the radio the others hear them marvel at a sky full of stars, then a buzzing, gunfire and silence. Teddy’s alternative is to bomb Judicial and cap the pipe, bystanders or not. Juliette refuses until Gloria Hildebrandt, of the Flamekeepers, now taken off the drug, reads from the diary of a porter named Mission, written while the silo was dosed 140 years ago: he cannot remember himself, and people starve or throw themselves from the stair. At the brink, Patrick’s voice on the radio stops the attack: he and Silo 17’s children are all right. In Washington, Daniel and Helen sign NDAs and fly with Charlotte, Anna and Victor to Stensen’s project in Georgia, where an enormous drill bores into the ground: the first silos.

From the books: Shift’s Mission Jones lives through Silo 18’s Great Uprising and ends memory-wiped; the series keeps him only as a diary. Georgia is the books’ site too, in Fulton County, but there Donald designs the silos himself.

Two figures in bulky hazard suits stand on a dark, barren hillside at night, their helmets tilted up toward a sky crowded with stars.
S3 · 11 Under the Stars With the drug already in the water, Juliette sends Lukas and Patrick out early, at night. Over the radio Walker and the others hear them mourn the wrecked land and marvel at a sky full of stars. Then a buzzing, gunfire, silence. In Dust the crossing to Silo 17 is made underground, through Juliette’s tunnel; the series sends two men over the hills and into someone’s sights.
An older woman reads aloud from a worn notebook by lamplight while a fair-haired woman and a tall, burn-scarred grey-haired man listen in a cluttered room.
S3 · 12 Mission’s Diary Teddy’s plan to reach the pipe means bombing Judicial, bystanders and all, and Juliette won’t approve it until Gloria Hildebrandt, of the Flamekeepers, now taken off the drug, reads from the diary of a porter named Mission, written while the silo was dosed 140 years ago. He cannot remember himself; people starve or throw themselves off the stair. Juliette says yes. Shift’s Mission Jones lives through Silo 18’s Great Uprising and ends memory-wiped; here he survives only on paper.
Episode 8

Gray Goo

Lukas, shot, and Patrick reach Silo 17 across a field of dead, and teenagers let them in. Jimmy “Solo” Conroy fixes their radio, and behind a welded panel they find his mother in a cleaning suit with her welding torch: she sealed the Safeguard pipe from inside. In Silo 18, Camille’s raiders arrest Juliette and lock her up with Robert; a secret elevator built to hide supplies comes to light, and so does Orla’s killer, Mike, who was stealing. In Georgia, Stensen and Thurman explain: fifty silos, human seed banks, against self-replicating nano-weapons that could reduce every living thing to gray goo. The Iranian dirty bomb was cover. Charlotte stays to fly for them; Helen calls them “Morlocks” and refuses, and so does Daniel, and in the departing helicopter they kiss.

From the books: the nanos are Shift’s reason for the silos: Thurman warns Donald of machines too small to see in 2049, but the whole truth comes from Erskine in Silo 1 in 2212, long after the end. In Shift Jimmy’s father is killed outside the server-room door, and his mother is dragged there as a hostage. Stensen’s “seed banks” are not the book’s Seed, a bunker beyond the dust.

In a dim, ruined concrete passage lit by a lantern, a long-haired bearded man and a wiry man in a brown jacket stand before an opened panel where a figure in a hazard suit lies slumped.
S3 · 13 The Welded Panel Shot on the way, Lukas reaches Silo 17 with Patrick across a field of rotting dead, and teenagers let them in. Talking with Jimmy Conroy in code, Juliette asks how his mother died stopping the Safeguard. Behind a welded panel they find her, in a cleaning suit with her welding torch: she sealed the pipe from inside, and Jimmy agrees at last to a funeral. In Shift Jimmy’s father is killed outside the server-room door, his mother dragged there as a hostage.
Beside an immense drilling machine boring into raw earth, a silver-haired woman in a dark suit and a greying man in a casual jacket talk with a man in a navy suit and a dark-haired woman.
S3 · 14 Fifty Silos Up close Stensen’s drills are vast, and he and Thurman lay it out: fifty silos, human seed banks to repopulate the Earth, against self-replicating nano-weapons that could turn every living thing to gray goo. The Iranian dirty bomb was cover, and Charlotte’s squadron was sent to test what Iran’s nanotechnology could do. Charlotte stays to fly for them. Helen calls them “Morlocks” and refuses, and so does Daniel. In Shift Thurman warns of the nanos in 2049; Erskine tells the rest in Silo 1, long after the end.
Episode 9

Farewell

Bernard gives himself up to Camille as a distraction, and the voice in the vault orders him out to clean without a suit. First he tells Juliette that the voice is a person in Silo 1: “the wizard is nothing more than a man behind a curtain.” The silo crowds the screens as he walks out and dies beside a dead tree, while Knox’s crew rides the secret elevator down with explosives toward the pipe. In the Before Times, time has moved on: Helen is pregnant, and Charlotte has married Anna. At the opening of the silos near Atlanta, Peter Gabriel, playing himself, sings “Here Comes the Flood”. Helen is sent on a tour of Silo 18, Daniel to Silo 1. On the phone to each other they see a nuclear flash and a wall of dust rolling toward the silos, and they are pulled underground into separate silos: Daniel into Silo 1, Helen, it seems, into the Silo 18 she was touring. Her fate is left open.

From the books: this is Shift’s 2052 convention on top of the finished silos: flashes on the horizon, crowds herded underground, Donald hauled into one silo while Helen goes into another, Silo 2, where she lives out her life married to Mick. The concert, the pregnancy, the marriage and Helen’s road to Silo 18 are the series’.

A tall grey-haired man in plain worn clothes and no protective suit walks slowly up a barren brown hillside toward a lone dead tree under a grey sky.
S3 · 15 Out Without a Suit Bernard gives himself up to Camille to cover the others, and the voice in the vault orders him out to clean without a suit. First he tells Juliette to be the leader the silo needs, and that the voice is a person in Silo 1: “the wizard is nothing more than a man behind a curtain.” The silo crowds the screens as he walks out, defiant, and dies beside a dead tree. Wool’s Bernard dies in the airlock fire.
Episode 10

Troy

Silo 1, some thirty-five years before the present. Daniel wakes from a bed of gooey liquid, and Victor calls him Troy. He is a crisis specialist for the Project, under its director, Thurman, and remembers nothing but flashes of a woman. Outside Silo 17 its rebels are breathing the open air, unharmed. The drone commander, “Susan”, who is Charlotte with her memory gone, refuses to fire, citing the Pact; Troy dismisses her and has the crowd poisoned and shot down by drones. In the present the Algorithm turns out to be Victor. About to gas Silo 18, he gives Camille five minutes, and she uses them to let Knox and Shirley clamp the pipe. Victor wakes Troy after thirty-five years and takes his own life. Under the silo, Juliette and her friends find a massive door, the “Forward Vault”. Troy offers peace if Silo 18 calls no other silo; Juliette accepts, and tells her friends they will attack Silo 1. Victor’s last video names the woman Troy remembers: Helen Drew.

From the books: Shift opens with Troy waking in a frosted coffin in 2110 and ordering Silo 12 gassed while he watches; Victor shoots himself; Silo 17 dies inside, gassed by Silo 1; and at the end Juliette answers Donald’s call. “We made him Daniel, but we kept him as Troy waking up,” Yost said. A massacre in the open air, Victor as the voice, “Susan” and the door are the series’.

A dazed dark-haired man sits up, dripping, in a shallow steel bed brimming with thick liquid while a grey-haired man in a white coat leans over him.
S3 · 16 Troy Wakes Daniel wakes in Silo 1 from a bed of gooey liquid, and Victor calls him Troy. He asks how long he has slept: seven years. He is a crisis specialist for the Project, under its director, Thurman, and remembers nothing but flashes of a woman. “We made him Daniel, but we kept him as Troy waking up,” Yost said. Shift opens with Troy waking in a frosted coffin in 2110, handed pills to forget.
In a dark control room lit by a wall of screens showing a crowd from high above, a fair-haired woman stands up from her console while a man in grey coveralls stands over her and an older man watches from the back.
S3 · 17 The Refusal Outside Silo 17, the rebels who walked out are breathing the open air, unharmed by it. On a monitor the drone commander, “Susan”, who is Charlotte with her memory gone, sees two of them kiss, is stirred by a memory of Anna, and refuses to fire, citing the Pact. Troy dismisses her and has the crowd poisoned and shot down by drones; Wikipedia counts 9,835 dead. Shift’s Silo 17 dies inside, gassed by Silo 1.
Standing in dark water, a fair-haired woman lays her hand on a colossal steel door set in a thick concrete wall, a small camera above it, three companions behind her.
S3 · 18 The Forward Vault The voice in the vault was Victor all along. About to gas Silo 18, he gives Camille five minutes, and she uses them to let Knox and Shirley clamp the Safeguard pipe. Victor wakes Troy and takes his own life. Following Lukas’s route, Juliette and the others find a massive door under the silo, which Silo 1 calls the Forward Vault. Troy offers peace if 18 calls no other silo. Juliette accepts, then tells her friends they will attack Silo 1.
Alone in a dim room, a dark-haired man in grey coveralls sits before a screen showing an older man’s face, tears on his cheeks.
S3 · 19 Helen Drew Victor leaves one last video. He was relieved, he says, when the Safeguard failed; and the woman Troy keeps asking about is Helen Drew. Troy weeps. Helen, pregnant, was touring Silo 18 when the bomb fell, and Den of Geek read a close-up of his eyes, matched to Juliette’s, as a hint that she may descend from him. In Shift Donald stops taking his pills and remembers on his own, and finds that Helen lived and died in Silo 2.

Continuity notes

  • Juliette ends the season with her memory back, still mayor, having accepted Troy’s truce at the Forward Vault and told her friends they will attack Silo 1. At the start of Dust the book’s Juliette is mayor too, burn-scarred and digging toward Silo 17; she later sets out for Silo 1 with dynamite, and uses it on the Seed’s door instead.
  • Bernard dies outside, suitless, in episode 9, nearly a season after the season 2 finale’s airlock fire, the point where Wool’s Bernard burns.
  • Lukas and Patrick are in Silo 17 with Jimmy Conroy and its young survivors; Lukas has been shot and patched up. Dust’s Lukas, head of IT, dies in Silo 18 when Silo 1 gasses it.
  • Camille Sims has turned against the voice; Robert Sims has been on Juliette’s side since he spared Bernard. Both turns are the series’ own, and Camille has no book counterpart; Dust’s Sims dies in the gassing.
  • Knox and Shirley clamped the pipe; Shirley is pregnant. Wool’s Knox dies in the uprising, and Dust’s Shirly stays behind to seal the tunnel, and dies with Silo 18.
  • Billings has solved Orla Kent’s murder (Mike, arrested); Dust’s Peter Billings dies in the gassing. Martha Walker and Carla McLain are alive; Dust’s Walker walks out to the Seed.
  • Silo 17: Jimmy has agreed to bury his mother, who sealed its pipe. Its rebels, who walked out some thirty-five years before the present (season 2’s opening scene), died outside, poisoned and shot down by Silo 1’s drones, not killed by the air.
  • Silo 1: Victor is dead by his own hand, as in Shift, where he shoots himself at his desk before Donald’s second shift. Troy, revived and remembering Helen’s name, is the voice now. Director Thurman is awake, visibly older. Shift’s Donald poisons Anna and shoots Thurman in 2345, and Dust revives Thurman to die when Silo 1 falls; none of it is in season 3’s episode summaries.
  • Charlotte (“Susan”) was dismissed for refusing to fire, some thirty-five years before the present. The book’s Charlotte is woken by Donald, escapes Silo 1 as it falls, and walks to the Seed.
  • Helen Drew, pregnant, was touring Silo 18 when the bomb fell, and was pulled underground. “You will find out what happened to Helen,” Yost promised. Shift’s Helen lives out her life in Silo 2 as Karma Brewer, married to Mick.
  • Still to come in season 4, the last: war with Silo 1, which is the series’ own (“Well, it is going to be war,” says Yost). From Dust, if the series follows the book at all: a dig and a crossing between 18 and 17; Silo 18 gassed and lost; Charlotte and Donald’s bomb, which brings Silo 1 down; the walk through the dust; the dome; the Seed; and the green world beyond.

The teaser shows Billings telling the other silos that one silo controls the rest, Juliette firing at a drone, and Juliette meeting Daniel in a tunnel and demanding to know who he is; he doesn’t know. Per Yost it adapts Dust.
