 On this, "Supernatural" co-executive producer Ben Edlund mentioned his view of Azazel as one of "a little cult of demonic true believers" that encompasses many of the important demon characters in the series.For Azazel's first full appearance on the series in "Devil's Trap", the writers initially could not decide which Winchester—Sam, Dean, or John—to have the demon possess.However, actor Jeffrey Dean Morgan's busy schedule made them realize that having John kidnapped and possessed, and therefore absent from much of the episode, would be the only practical choice.
