Season 2: Episode 116

After an explosion rocks the auto plant, Texas admits to Vernon that it was the result of his bomb, not the noxious fumes reported by Mary. Howie receives a death threat warning him to stop his secret society investigation, and Cathy suspects him of being a virgin. Mary, George, and Tiny are trapped beneath the rubble of their collapsed work area. At the Capri, Lila shows Wanda's diary to Texas, but Martha swipes it. Texas and Vernon spot a convenient scapegoat for the bombing: Dewey, the auto plant's black janitor.
