Bluebeard's Castle is the tenth and final episode of the first season of You. It is the tenth episode of the series overall. It aired on November 11, 2018 on Lifetime.
Synopsis[]
Beck's deepest truths are revealed; Joe pushes the limits of what he'll do for love.
Plot[]
The episode begins with Guinevere Beck imprisoned in the glass cage beneath Mooney’s bookstore, placed there by Joe Goldberg after she discovered his collection of mementos from his victims. Joe attempts to justify his actions to Beck, claiming that his previous murders were acts of protection or justice. He provides her with a typewriter, urging her to write a story that explains their situation from his perspective.
Beck feigns compliance, crafting a narrative that portrays her therapist, Dr. Nicky, as a manipulative figure responsible for the deaths of her friends. She uses this fabricated story to gain Joe’s trust, ultimately managing to escape the cage and lock Joe inside. However, her attempt to flee is thwarted when she discovers the basement door is also locked. Joe had anticipated such a scenario and had hidden a spare key inside the cage, allowing him to free himself and recapture Beck. Subsequently, Joe murders Beck and frames Dr. Nicky for her death, using the manuscript she wrote as evidence.
In a subplot, Joe intervenes in the life of his neighbor, Paco, whose mother, Claudia, is hospitalized after an altercation with her abusive boyfriend, Ron. Joe confronts Ron and kills him to protect Paco. Later, when Beck pleads with Paco for help while imprisoned, Paco, recalling Joe’s previous assistance, chooses not to intervene.
The episode concludes with a time jump, showing Joe back at the bookstore, where Beck’s posthumously published work is on display. A woman enters the store, revealing herself to be Candace, Joe’s ex-girlfriend, previously presumed dead. Her unexpected return sets the stage for the next season.

Trivia[]
- The title “Bluebeard’s Castle” is a direct reference to the French folktale about a murderous nobleman who hides the bodies of his wives in a locked room—paralleling Joe’s hidden crimes and the glass cage.
- The episode marks the death of Guinevere Beck, making her the final major victim of Season 1. This outcome mirrors the original Caroline Kepnes novel, in which Beck also dies.
- Beck’s attempt to manipulate Joe by writing a manuscript from his point of view was a narrative device added for the show and is not present in the book.
- The revelation that Joe had anticipated Beck’s escape and planted a key in the cage reflects his deeply methodical nature and planning, reinforcing his psychological dominance.
- Dr. Nicky, portrayed by John Stamos, is framed for Beck’s murder, setting up a major storyline in Season 2 involving wrongful imprisonment and justice.
- Beck’s posthumously published book being displayed in the bookstore creates a dark irony—Joe is benefiting socially and professionally from her death.
- Paco’s refusal to help Beck, despite hearing her cries for help, is a pivotal moral moment in the series, showing how Joe’s influence has corrupted even a young child.
- Ron’s off-screen death at Joe’s hands brings closure to Paco’s storyline and represents Joe’s ongoing pattern of removing perceived threats under the guise of protection.
- Candace’s return in the final scene was a surprise reveal not present in the book, serving as a cliffhanger that confirms she is alive and sets up the central tension for Season 2.
- The glass cage used throughout the season is symbolic not only of Joe’s obsession with control but also of how he tries to preserve people, as if they’re rare objects or texts.
