season, Morgan became frustrated at times due to his character's avoidance of his sons, stating, "It pissed off everybody, it pissed off us as actors, it pissed off the audience watching, because none of us really knew where we were gonna go." However, he reasoned that John's motivation for his actions was due to having knowledge that nobody else had. During production of Supernatural's first season, Morgan was also working on the shows Weeds and Grey's Anatomy, so he was often traveling back and forth between Los Angeles and Vancouver, British Columbia. This interfered at times with Morgan's acting, as he had trouble getting "Winchester-y enough" after portraying the nice character of Denny Duquette on Grey's Anatomy. Morgan commented, "I was stuck in Denny-land, where I was being too nice. Winchester's harder to find. Denny's more me. He's an intense guy, John is. And Denny, for a guy who's having trouble living, he's just a charming dude." Morgan was at first reluctant to return for Supernatural'''s second season due to his role on Grey's Anatomy.

Nevertheless, both Kripke and writer Sera Gamble have stated that they "would love to have him back." The scheduling conflict has continued into the sixth season of Supernatural, with executive producer Robert Singer revealing that the writers had considered bringing the character back in the alternate reality episode "My Heart Will Go On" instead of Ellen Harvelle, but due to concerns that they would not be able to secure Morgan's return, they ultimately chose Ellen for the deceased character they would have (temporarily) return in the episode. During the production of the fifth season, Morgan had an interview with MovieWeb in which he stated that no one from the show had contacted him about making another appearance, and expressed the desire to return for at least one more episode in what was then-believed to be the show's final season, as he had enjoyed working with Ackles and Padalecki, and he felt that John's storyline had ended too soon. Reception While critics praised Morgan for his performance in the role, their reaction to the character has generally been mixed. Don Williams of BuddyTV felt that John is a "rather divisive character", with some fans
