Hereditary Ending Explained

Ari Aster’s Hereditary (2018) concludes with a disturbing ritual sequence that reveals the true nature of everything that has happened throughout the film. Here is the complete breakdown.

Who Is Paimon?

Paimon is one of the eight Kings of Hell in demonology. The cult, led by grandmother Ellen, has been working for decades to summon Paimon into a human host. Paimon requires a male host from Ellen’s bloodline. Charlie was the original vessel, but Paimon needs a male body — which is why Charlie had to die so the demon could ultimately transfer to Peter.

The Final Sequence

Annie, now possessed, chases Peter through the house. Peter sees naked cult members standing in shadows throughout the home. Annie floats to the ceiling and decapitates herself with a wire. Peter jumps from a window and lies motionless. A light enters his body — Paimon has found his male host.

Peter/Paimon walks to the treehouse where a headless mannequin wearing Ellen’s body sits on a makeshift throne alongside Charlie’s severed head. The cult members bow. Joan crowns Peter/Paimon as the King of Hell. The ritual that began with Ellen’s death is complete.

What Was Real?

Everything was orchestrated by the cult from the beginning. Ellen’s death, Charlie’s accident, Annie’s grief spiral, the seance — all were stages in the summoning ritual. The family never had a chance. This is the film’s most disturbing element: not the horror itself, but the realization that free will was an illusion throughout.

Frequently Asked Questions

Was Charlie always possessed by Paimon?

Yes. Paimon inhabited Charlie from birth (Ellen “claimed” Charlie as a baby). But Paimon requires a male host to reach full power, which is why the cult engineered events to transfer the demon from Charlie to Peter.
