Later in the season, John is captured by demons, and the brothers manage to rescue him. However, they soon learn that the demon who killed their mother is in possession of their father's body. Though John begs Sam to kill him, Sam instead shoots John in the leg using the Colt, and the demon escapes. As Sam drives his father and a badly wounded Dean to a hospital, a truck driven by a demon-possessed man crashes into them, totaling Dean's Impala and gravely injuring the Winchesters.
