The narrative reaches its turning point when Rebecca discovers that the demonic possession is not accidental: Raymond intentionally lured her into the facility because the demonic entity had marked her. Following Raymond's occult instructions, Rebecca identifies the demon's sigils, applies them to the correct corpse, and burns it in the mortuary crematorium retort, believing she has broken the curse. However, she is promptly pushed down the stairs by a manifestation of her father Ben, revealing a repressed memory: years earlier, when she nearly drowned while intoxicated, Ben broke his neck while saving her life, a catastrophe manipulated by The Mimic. In her unconscious state, Rebecca meets Ben's spirit, who urges her to stop reliving his death and forgive herself.
Upon regaining consciousness, Rebecca investigates the forbidden basement and discovers Vallery, a woman kept locked in a coffin. When Rebecca unlocks the container, the possessed Vallery attacks her, only for Raymond to intervene using occult sigils tattooed across his chest to subdue the demon. Raymond confesses that Vallery's demonic blood is the crucial reagent used to keep the entity from spreading, admitting that he needs Rebecca's help to sustain this ritual. Although Rebecca initially attempts to leave River Fields Mortuary, she steps outside only to spot The Mimic watching her from across the street; realizing that running away will never free her from its grasp, she chooses to re-enter the mortuary and stand her ground alongside Raymond.
