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 it was unclear whether Dax and Enina were about to kiss. It was decided at the time that it was not appropriate, although the writers had hoped that there would be a time when the viewers would accept such a relationship. This theme was eventually realised 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 at the time, citing both "Rejoined" and the Mirror Universe episodes as examples, even if the presented bisexuality is problematized.
