The writers intended for the character to make only two guest appearances in the third season, which left Ferris "a bit surprised and at Ellen's lack of involvement. However, her initial return was scrapped due to the 2007–2008 Writers Guild of America strike, and the actress declined a guest appearance in the finale because the lackluster offer "could cost [her money and work." The opportunity to return for the fifth season surprised her due to the large time span since her previous appearance. Though she expected her character to eventually die, a devastated Ferris was surprised at how quickly it occurred. However, after speaking to director Phil Sgriccia—he told her that Ellen was the "perfect fodder" for the "kick" that the series needed, and would "go out in a blaze of glory"—the actress came to realize that the character's death made sense. Ellen's last words to Dean—"Kick it in the ass."—was an improvised homage to the late "Supernatural" executive producer and director Kim Manners, who had died the year before and would often recite the phrase before filming a scene.
