Jack Ewing left Dallas to continue his travels and get away from J.R., midway through season 10, and returned a final time for two episodes towards the end of the season. While there has been no official reason as to why actor Dack Rambo was written out of "Dallas", Rambo himself later stated that he believed the reasons to be his bisexuality and/or his conflicts with Larry Hagman, which Rambo said had particularly intensified during his last season on the show (season 10). Before "Dallas", Rambo and Hagman had worked together on "Sword of Justice" in the late 1970s. Hagman later denied any involvement in Rambo's dismissal from "Dallas".
