The Fallout Season 2 Finale, Explained Amazon Prime Video

Spoilers below.

The more the Fallout universe expands, the harder it is to tie all the threads together, from the various factions to more complicated elements of world-building. The show also frequently jumps from one timeline to another, showing the pre-nuclear war world and, this season, the rise of tech maniac Robert House (Justin Theroux). House seems to be behind many of Vault-Tec’s innovations, but season 2 also introduced The Enclave, an even more evil and shady organization experimenting on the populace. With all that in mind, season 2, episode 8 does its best to converge these storylines, answer a few questions, and present more mysteries for next season, which has already been renewed.

The episode opens with an explosive fight scene, with a Lacerta Legate (Macaulay Culkin) of Caesar’s Legion finding a note on his former leader’s corpse that does not name a successor. He stabs his compatriot, hides the note, and takes the crown. He is the new Caesar, promising to take over New Vegas.

New Vegas, however, is not looking so hot. The Ghoul (Walton Goggins) is there, confronting a video version of Robert House that seems to be sentient. (The House always wins!) He lives on through screens, having found the human body too vulnerable. The Ghoul wants to know what will happen if he destroys the source of House’s power, perhaps by shooting it. House warns him that blowing up the infinite energy diode to kill him might explode the planet. But the Ghoul still says he’ll do it unless House directs him to his family’s vault. To do that, the Ghoul puts on a portable screen wristband and starts following directions.

Meanwhile, the Deathclaws are making their escape through the soldier-shaped hole in the wall of their enclosure that Maximus (Aaron Moten) created last episode. He discovers new aspects of his suit and starts shooting off missiles as the townspeople hide. But there are ultimately too many Deathclaws to fight and they’re on the loose through the city.

Lucy (Ella Purnell) is confronted by the head of the unfortunate congresswoman who helped trick Cooper into giving up the diode 200 years ago, powering all the mind control units. The head is alive and attempting to communicate. She begs for death, but that is not something Lucy wants to do.

“Why does everyone want me to kill them all the time!” she screams, before whacking the congresswoman with a crowbar and bringing the room to a stop.

The newly awakened Vault 31 executives are dragging Norm (Moisés Arias) to his death and end up injuring their coworker, Claudia, in the elevator bay. The elevator doors open, and a swarm of massive, deadly roaches enter and start killing, which is perhaps one of the most horrible ways to die in Fallout. They’re soon all over everyone. The execs attempt to keep Norm out of the safe room, and he ends up being the only survivor as the roaches flood their lounge and he hides under a coffee table.

House is telling the Ghoul all about his evil plans and how he rigged Vegas for control as the Ghoul makes his way to his family’s cryo-chambers. However, this vault belonged to investors, not to Vault-Tec, and they were ahead of him, releasing the Deathclaws on Vegas. House tells the Ghoul that he was responsible for handing off the diode to the president and thus, The Enclave, not House.

Lucy wanders the same Vegas vault where she is confronted by her father, Hank (Kyle MacLachlan). He explains House’s plans to make everyone an automaton and attach devices to people that control their minds. But Hank wanted to make them a bit more lively. His goal is miniaturization, or in other words: making House’s original mind control device so tiny you won’t even know who is being controlled. And Lucy is going to be his next experiment and become his “little girl again.”

In a flashback, Ghoul as Cooper and his wife, Barbara (Frances Turner), are making plans to leave Vegas, perhaps for Colorado, when they meet young Hank and Stephanie, who are engaged. Stephanie (Annabel O’Hagan) was a maid at the time and Barbara says maybe she can help find her a job with Vault-Tec. In the penultimate episode, Stephanie was seen escaping Canada for the U.S. with her mom, becoming a ruthless killer to survive. How she ends up on Hank’s arm isn’t yet clear. As Cooper and Barbara walk through the lobby, all the pay phones start ringing at once.

In the present, Maximus is still getting wailed on and the townsfolk of New Vegas are taking bets on how long he will last. His only friend, Thaddeus (Johnny Pemberton), bets 500 caps that Maximus will survive. Of course, if Maximus loses, everyone dies. He manages to kill one Deathclaw, but more and more keep coming, and his suit is taking a lot of damage. Thaddeus climbs up on a roof, sniping the monsters, but it’s not enough. Maximus thinks of his family when he was a kid, encouraging him to be a “good man.”

Scooting out of his suit, he takes on a Deathclaw with a pole and a roulette wheel as a shield. The townsfolk see him for the first time and want to fight with him. (Well, some of them do.) But thankfully, yet another sniper is up on the roof that starts exploding Deathclaw brains. It’s the army of the New California Republic.

The Ghoul gets through the vault and manages to just save Lucy from brain control surgery. He lets her decide what will happen to her dad, kicking a gun over to her. Instead of shooting Hank, her eye wanders to the brain control device. She attaches it to him and walks him out of the vault. She tells him how much she used to dream of leaving the vault with him. He says he dreamed of returning. But he knows they won’t.

Hank warns her that the Legion is coming to New Vegas and they’ll massacre everyone—but he can help. She demands to know what he was really doing in New Vegas before she uses the device to turn him back into the father she thought he was. He tells her that the surface is the experiment, not the vaults. The people he controls are already out, and no one can recognize them. They have their orders and he hits the switch to activate them, which seems to trigger his own device as well. Hank goes catatonic after telling Lucy he loves her.

When he opens his eyes again, Hank does not know who she is. Weeping, she leaves him behind. But she doesn’t seem sure where to go.

Then, Maximus appears. The pair is finally reunited.

Back in Vault 32, Stephanie is in her office and the Vault folk are banging on her door and getting worked up about sending a message to Management—a deadly one. She opens the “keepsake box” she got from Betty, revealing a wrist monitor. She puts it on and starts emergency protocol, calling herself Hank’s wife. She tells an unseen listener to “initiate phase 2.” The message is received at a bunker covered in satellites, which seems to be receiving all sorts of information. Who is listening?

Back at the roach massacre, Norm surveys the death toll, though it’s unclear where the roaches ended up. Claudia is alive, barely. He drags her out and away.

The Ghoul is still searching for the cryogenic chambers containing his wife and daughter, Janey (Teagan Meredith), as House warns him there is nowhere for a reunited family to go. In the flashback, Cooper answers one of the ringing pay phones. It’s a phone call from House, who tells him he is not responsible for whatever is about to happen. He and his wife are surrounded by sinister men. They arrest him for Un-American Activities, taking him from Barbara, who he wants to sell him out. He tells her to insist she didn’t know anything about any of his activities.

In the present, he enters the chambers, seeing Barbara’s name and Janey’s above her. House opens them, but there’s no one inside. There is, however, a postcard that reads, “Colorado was a good idea.”

House tells the Ghoul he bet on hope for no reason. The Ghoul insists he was right. Now he knows Barbara left him a message and could be alive. He leaves the House monitor behind and heads out to find his family.

The Legion is marching on New Vegas. Lucy and Maximus enter House’s apartments, but the monitor where he appeared reads “Signal Lost.”

Looking below, they see war approaching. He takes her hand, and they turn to face it together.
