Hereditary’s ending is a coronation, not a tragedy — at least not for the cult. After the Graham family is destroyed, the demon Paimon finally claims its intended male host: Peter. In the backyard treehouse, cult members crown him and chant “Hail Paimon,” while the headless bodies of his mother and grandmother bow before him.
Recap: The Graham Family’s Destruction
After the death of her secretive mother Ellen Leigh, miniature artist Annie Graham begins uncovering disturbing family history: her father starved himself, her brother died by suicide, and Ellen had insisted on nursing Annie’s daughter Charlie herself. Charlie, a strange 13-year-old, admits her grandmother always wanted her to be a boy.
The catastrophe begins at a house party. Charlie suffers a severe allergic reaction; her brother Peter rushes her home, and with her head out the car window, she is decapitated by a telephone pole. Annie joins a grief support group, where she befriends Joan — secretly a high-ranking member of Ellen’s cult — who steers Annie toward a séance.
The séance escalates the haunting: doors move, lights flicker, Peter is slammed face-first into his school desk by an invisible force. Annie discovers Ellen’s occult books, photographs of Ellen with Joan, and a decapitated corpse in the attic crawlspace. The final night, her husband Steve bursts into flames, and a possessed Annie saws at her own neck with piano wire.
The Final Act, Scene by Scene
The climax opens with Annie possessed, crawling along the attic ceiling and decapitating herself with wire, as Steve’s corpse burns behind her. Peter wakes, discovers his father’s body, and watches his mother’s floating, headless corpse pursue him.
Terrified, Peter climbs out of the attic window and jumps. He falls dead — and a small light drifts into his body. He stands, clicks his tongue (Charlie’s signature tic), and walks calmly toward the treehouse where Charlie used to sleep.
Inside the treehouse: naked cult members bow before a wooden mannequin topped with Charlie’s decomposing head, wearing a golden crown. The headless bodies of Ellen and Annie kneel in worship. Joan crowns Peter — addressing him as “Charlie,” then as Paimon, one of the eight Kings of Hell. The film ends on the cult chanting “Hail Paimon” as the camera pushes in on Peter’s blank, newly inhabited face.
What the Clues Were Telling You
The film plants its machinery in plain sight. Ellen was the cult’s leader — “Queen Leigh,” as her funeral placard reads — and her dying wish was a vessel for Paimon. Charlie was possessed by Paimon from birth, which explains her strangeness, her clicking tic, and why Ellen wanted her to be a boy: the demon requires a male host, and Charlie’s female body was always a temporary, unsatisfactory container.
Every horror set piece was the cult softening Peter up. Paimon needs a psychologically vulnerable host: the desk-slamming was the demon trying the door, and the grief, guilt over Charlie’s death, and the final night’s terror kicked it in. Aster described the film as “a story about a long-lived possession ritual told from the perspective of the sacrificial lamb.”
Competing Interpretations
The supernatural reading (Aster’s own). Aster has confirmed the cult’s plan is real within the film’s world: a multi-generational conspiracy to install Paimon in a male Graham heir, and it succeeds completely — from Ellen and the coven’s point of view, the ending is a triumph. The grief-and-illness reading. Others read the haunting as a metaphor for a family collapsing under inherited trauma and mental illness — the cult may be real or may be the shape Annie’s grief takes. The film never fully closes this door, which is why the ending lingers.
FAQs
Who is Paimon in Hereditary?
Paimon is a demon from real-world occult texts (notably the Ars Goetia), described as one of the Kings of Hell who grants knowledge and devotion to followers. Ellen’s cult worships him and spent generations preparing a male Graham heir as his vessel.
Why did the cult want Peter instead of Charlie?
Paimon requires a male host. The demon occupied Charlie’s female body for 13 years because Annie kept Peter away from Ellen, but the cult considered it a mistake to be corrected — hence Joan’s line about a “healthy male body.”
Is Peter dead at the end?
Effectively, yes. When Peter jumps from the attic window, his body dies and his consciousness is displaced so Paimon can take residence. The tongue-click and blank stare confirm Peter the person is gone; what walks to the treehouse is the demon.
Why does Joan call him “Charlie”?
Because “Charlie” was the only identity Paimon wore among the cult during its 13 years in her body — the name transferred with the occupant. Joan addresses the demon by the name it answered to, before proclaiming its true title: King Paimon.
Was the treehouse ending always the plan?
Aster settled on the ending very early, but it was originally scripted differently: Peter would go to the treehouse, the film would fade to black, and Joan’s crowning speech would be delivered in her apartment two weeks later.
What does “Hail Paimon” mean for the family?
It means the ritual worked exactly as Ellen designed it. Annie only ever had children to complete it — a fact Aster confirmed was intentional. The Grahams’ suffering was a decades-long harvest, and the final chant is the cult celebrating its success.
