Legion is a cluster of multiple demons that was implanted into Amy Dukane by a single demon entity.

The demon later used Amy's body to commit further violence, including killing her boyfriend Robby.

Foreshadowing: The demon's attack on the burglar, which involved disembowelment, foreshadows the invasive nature of how it would later embed Legion into Amy.

The cursed lumber originally came from 112 Ocean Avenue, the famous Amityville house that was previously haunted. Father Jonas performed an exorcism there that ended with his death. Charles Humes, a general contractor, took wood from that house and used it in his own home and other properties. The demonic entities from 112 Ocean Avenue then spread through this lumber, infecting multiple houses and the people living in them.

Foreshadowing: Charles reveals that he added the tainted wood to his own home and other properties, setting up the widespread haunting that Father Benna must later address.

Father Jonas, Father Benna's brother, performed the exorcism on 112 Ocean Avenue that ended with his death. The demon killed him during the attempt to cleanse the house.

Foreshadowing: Benna's lingering guilt over Jonas's death is established early, foreshadowing the danger he faces during Amy's exorcism.

While Amy was walking in the woods, the demon possessing her took control and attacked a photographer who was in the area. Under the demon's influence, Amy was responsible for the photographer's death. This event demonstrates how the demonic possession extended beyond the house, allowing the entity to harm people nearby.

Foreshadowing: The demon's earlier attack on the burglar showed its ability to act through Amy outside the home, foreshadowing the photographer's murder.

Jeremy Dukane, Amy's abusive alcoholic father, became a target of the demonic haunting after initially remaining skeptical about the supernatural activity. The demon tormented him with visions of his deceased wife Bonnie, who died in a drunk-driving crash that Jeremy himself caused. These terrifying visions were meant to break his resistance and deepen his psychological suffering.

Foreshadowing: Jeremy's backstory establishes that he caused Bonnie's death, which the demon uses against him during the haunting.

During the exorcism, the demon that implanted Legion in Amy taunted Father Benna. In response, Benna drew a cross in his own blood, blood from a wound Amy had inflicted on him. The bloody cross was able to banish both the individual demon and Legion back to Hell, freeing Amy from possession. This desperate act became the turning point that defeated the demonic force.

Foreshadowing: Benna's willingness to sacrifice himself echoes his brother's earlier sacrifice, completing the thematic arc of religious redemption.
