Orell Peattie (played by Billy Drago) was the father of Lynette Peattie, who was mortally wounded in a bus accident and given a lethal dose of morphine from Dr. Robert Wieder. Shortly after Wieder and his family returne home from an awards ceremony, Peattie used a poppet to kill Wieder's father-in-law, Irving Thalbro, who was found in their home with a slit throat hanging from a noose. Mulder and Scully were called in to investigate when signs of hexcraft were found on the premises. Soon, Peattie struck Wieder's wife with an intense outbreak but she was able to survive long enough to make to a hospital. At the hospital, Peattie confronted Wieder and told him to remember Lynette Peattie, but Wieder had no idea what he was talking about.
Peattie returned to the hospital with Mrs. Wieder was scheduled to have an MRI done. Peattie placed a poppet of her inside a microwave, and she was grilled alive inside the MRI machine. Mulder and Scully learned that Lynette Peattie was a Jane Doe handled by Wieder in late 1999. The agents realized that Peattie was using an Appalachian magic-like power to seek revenge by attacking Wieder's own family. Wieder and his daughter were sequestered with Scully to a cabin far from the city with the hope that Peattie would not be able to use his power against them. The agents had learned that Peattie used a charm as the source of his power. Mulder was able to find the charm - his daughter's corpse - inside Peattie's apartment, but the skull was missing. Peattie had indeed followed Wieder and Scully.
Peattie made another poppet, this one of Scully, and used to blind her while he entered the cabin and took her gun. He then used a poppet for Wieder to inflict terrible chest pain while his daughter screamed for mercy for her father. Mulder arrived shortly thereafter and found the skull. Depriving Peattie of his power, Scully regained her eyesight and shot Peattie in the back, saving Wieder's life. Peattie was grievously wounded, but survived. (TXF: "Theef")
