this, the original teaser depicted the supernatural deaths of Bobby's children; while eating dinner with his family, his children's throats are supernaturally slit, and they would ask him, "Why, daddy, why did you let this happen?" However, the writers could not determine where to go from there. Following Humphris' earlier pitch of Bobby being an expert exorcist because of a previous failed exorcism, the focus changed to Bobby's torment about killing his demonically possessed wife. Other planned dream sequences were drastically altered due to production issues. One such scene, made to look like 80's-style film stock, had Dean being confronted by serial killer Jason Voorhees of the Friday the 13th film series. After production cleared the rights to use the character, Kripke made everyone view Friday the 13th: The Final Chapter to help them create the "perfect facsimile" of Jason. However, the film studio that had granted permission realized a few days before filming that it did not actually own the rights. In dire need of a new concept, the writers recalled Sam's dream sequence with Bela; since Sam is revealed to be a "horn dog" underneath, the writers wanted Dean to be the opposite. Dean secretly desires a normal family, so they had Cindy Sampson reprise her role as Lisa Braeden—Dean's love interest from "The Kids are Alright". On retrospect, Kripke preferred this scene over Jason because it is more illuminating of Dean's character. Dean's other dream is a major turning point in the character's storyline, after which he starts gaining self-respect and realizes that he truly wants to live. He begins the season with little self-worth, and the writers realized that this outlook stems from his father, John Winchester. Initially, they planned to have Jeffrey Dean Morgan reprise his role as John, who would browbeat Dean within the dreamscape. When they learned that Morgan was busy filming Watchmen, the writers instead found inspiration in the junkyard scene from the film Superman III, in which good and evil versions of Superman confront one another. Kripke noted, however, that the conversation between the two Deans still focuses on John. Filming Principal filming took place in Vancouver, British Columbia, with Bobby's hospital scenes being filmed at Eagle Ridge Hospital in Port Moody, British Columbia. To distinguish the dream sequences, director of photography Serge Ladouceur used full blue lighting in the backgrounds—he normally uses half. The seamless transitions between dream scenes were
