This article contains plot spoilers for the 2017 series of Twin Peaks.
Billy was Audrey Horne's extramarital lover.
One day, Billy witnessed Chuck stealing his truck and called the sheriff. The truck was later found without incident. The following week, however, Billy went missing. Chuck told Audrey that Tina had been the last person to see him. Audrey had a dream where Billy was bleeding from his nose and mouth.
Two days after Billy's disappearance, Audrey browbeat Charlie into going to the Roadhouse with her to look for him, even though Billy supposedly hated the place. Charlie called Tina to ask about Billy, but got some disturbing news.
At the Roadhouse, Tina's daughter Megan told Sophie that Billy had recently jumped over a six foot fence and run into their kitchen while bleeding profusely, holding his head in the sink before running out again. The episode, lasting about ten seconds in total, was witnessed by Tina and Megan, and possibly Megan's uncle.
