Our geriatric duo is now going after Junius Watts. Watts has been expecting them—he’s the one who’s been surveilling Wayne. Watts helped Hoyt raise his daughter, Isabelle after he lost his wife. Isabelle went to college and met a man, with whom they had a child, Mary. The Hoyts were happy until the husband and child skidded off a mountain on their way to meet Isabelle. Isabelle became worse than sad and started taking lithium. One night, Isabelle takes a car and tries to smash it up. Harris James helps them keep it quiet.
Then in 1979, at an employee picnic, she sees a little girl, and goes out and tries to grab her. Watts pulls Lucy (Mamie Gummer) aside and talks to her about letting Miss Isabel play with Julie. Lucy says it’s OK, but she wants money, and she wants the brother to be there to keep an eye on her. For a little while that works. But then Isabelle wants to adopt the girl. Isabelle is confused because she’s stopped taking her meds and believes Julie is Mary (MARY JULY, y’all!).
A tug-of-war in the woods results in Will’s accidental death, and Watts is tasked with bringing him to the cave. It’s Julie who clasps his hands in prayer. Hoyt’s on safari and knows nothing about this. Harris James stages Woodard’s house with the backpack. Harris explains the accident to Lucy and offers her a lot of money in exchange for Julie.
Julie lives in the pink basement, happily, for a couple of years until Watts realizes Isabelle has been drugging her with lithium since she was 10 years old. When Julie grew up, she started asking questions and experiencing memories of her brother, leading Watts to help her escape the dungeon. He gave her a map to a meeting point, but she never showed up and he’s been looking for her ever since. After Julie ran off, Isabelle had a breakdown and killed herself.
In 1997, Watts finds out where she went. She’d been working in a convent and called herself Mary. She stayed for three and a half years. She had HIV. They took care of her, but in a few months, she was gone. According to her gravestone, she passed in 1995. Watts is ready to be killed or taken in, whatever these guys decide. Old Wayne and Roland put their guns away, deciding the best punishment for Watts is to let him live with his guilt.
Wayne and Roland visit Julie’s grave, apologizing for the shoddy job they did on her behalf. All of a sudden, Mike the caretaker of the convent, comes out to tell his daughter, Lucy, to stop running around. Can’t be a coincidence. The two go back to Wayne’s and start packing up the boxes of paperwork that Wayne has been pouring over. The two of them don’t feel any kind of closure…and with 30 minutes left of the finale, neither do we.
