Fallout Season 2: Lucy's Big Decision In Episode 7, Explained

Warning, Wastelanders: This article contains spoilers for "Fallout" season 2, episode 7.

To anyone under the impression that "Fallout" isn't the most wholesome show currently streaming, how do you explain an entire storyline in episode 7 dedicated to a daughter bonding with her long-lost dad? Okay, fine, that might be overstating things. The scenes between Lucy MacLean (Ella Purnell) and her wayward father Hank (Kyle MacLachlan) are only as nice and sweet as this post-apocalyptic wasteland will allow — which means, of course, not at all.

Fresh off her hands-on demonstration with those brain control chips from last week, proving that Hank is far more dangerous that she ever thought, Lucy spends much of the episode (titled "The Handoff") agonizing over one particularly tricky moral dilemma. While Lucy recognizes that stripping away free will from people is obviously wrong, she begins to see things from her father's perspective. Activating the brain chips narrowly prevents some grisly bloodshed involving the members of rival clans in Vault-Tec's headquarters, after all. And, compared to the cheerful efficiency of all the former Wastelanders who now work under Hank's careful eye, doesn't that beat the alternative of the bloodthirsty Legion killing and enslaving countless innocents on the surface?

These pesky rhetorical questions build and build until culminating in one of Lucy's biggest moments of the season so far: Whether to join her father or bring him to justice, as she planned all along. Give her this much credit, at least; when she commits, she commits. During an otherwise unassuming supper, Lucy lulls Hank into a false sense of security before handcuffing him to an oven, making her escape, and setting her sights on taking down the mainframe that will end these horrors once and for all. Let's dig into how she arrived at this conclusion.

For all the zany concepts and post-apocalyptic violence that make up every idiosyncratic detail in the world-building of "Fallout," from bottle caps to radioactive ghouls to oversized monsters itching for a fight, one key aspect has stayed in focus throughout both seasons. At its core, the Prime Video series remains a character-driven story about Hank and Lucy, two go-getters with very different ideas of how to get things done.

In the excellent "Fallout" season 2, this MacLean vs Maclean drama takes on an even greater sense of import. No matter what the Wasteland throws at her, Lucy has stubbornly refused to compromise on any of her values. Not even Walton Goggins' rough-and-tumble gunslinger The Ghoul could shake her loose from her ideals. The one person who's come closest, it appears, is her own father. And she very nearly crosses that line until one figure from the recent past shows up again at a crucial turning point. It seems inevitable that Lucy will reluctantly side with Hank, even going so far as to ditch her Vault jumpsuit and don a yellow dress — a visual reminder of happier days with her dad. But when a serving man under Hank's mind control obediently pours water for them, Lucy realizes that this is the same soldier from the New California Republic that she and The Ghoul encountered back in episode 4.

Even the most harmless members of the surface world aren't safe from Hank's obsessive quest to save the world, apparently, and that finally gives Lucy enough evidence to make her final choice. Under the guise of freeing her father, she instead handcuffs him to an oven and runs for the mainframe. Unfortunately, things are never quite so simple in "Fallout."

Let's not lose our heads or anything, folks. Remember that earlier point about how "Fallout" isn't exactly a feel-good story? Well, that tendency to opt for the darkest, most absurd scenario imaginable rears its horrible head again at the conclusion of this subplot. Just when Lucy delivers a stand-up-and-cheer moment by staying true to her own moral code, we're served yet another gut-punch ending. After unlocking the vault protecting the mainframe and bursting inside to put an end to Hank's shenanigans, Lucy is met with an unsettling sight: a decapitated head kept alive by electrical wires and some sort of a breathing tube.

Well, so much for any sense of triumph. Worse yet, we actually know who that head belongs to and the implications are ... not great! While this storyline has been unfolding in the present, a series of flashbacks take us through Cooper Howard's conspiratorial arc in Las Vegas before the bombs ever dropped. He once again meets with one Representative Diane Welch (Martha Kelly), the political figure who has been one of the few outspoken voices against the tech leaders running the world. She confides to Cooper that she's able to broker a meeting with the President of the United States himself (certain to be a familiar face to video game fans) and can be trusted to be given the cold fusion device causing all this havoc. Well, so much for that. The decapitated head turns out to be Welch, leaving Lucy horrified by the fact that there appears to be no bottom to Vault-Tec's (and her father's) depravity.

We'll find out exactly where this is all going when the season 2 finale of "Fallout" streams on Prime Video Tuesday, February 3, 2026.
