Writers on "Deep Space Nine" had previously hinted at a potential same-sex relationship in the episode "", when Jadzia Dax says goodbye to Enina Tandro, a former lover of Dax's previous male host, Curzon. The first take of the scene resulted in a situation in which whether Dax and Enina were about to kiss was unclear. It was decided at the time to be inappropriate, although the writers had hoped that a time would come when the viewers would accept such a relationship. This theme was eventually realized in "Rejoined". Allen Kwan has argued that "Deep Space Nine" is the only series of "Star Trek" that resists the heteronormativity typical of the franchise, citing both "Rejoined" and the "Mirror Universe" episodes as examples, even if the presented bisexuality is problematized.
