someone you love and having that person restored to you some time afterward. Following the death of Jadzia in the sixth season finale, "Tears of the Prophets", Farrell suggested that the symbiont could be moved to a male character resulting in a similar situation as "Rejoined" between the new Dax host and Worf, as the two were in a relationship at that point. Instead, the symbiont was placed in a new female host called Ezri, as the producers did not want Kira Nerys to be the only female main character. The prejudice against re-association first highlighted in "Rejoined" was mentioned in seventh season episodes such as "Afterimage". Visual effects and guest stars Visual effect supervisors Gary Hutzel and Glenn Neufeld were busy completing post-production work on the opening episode of the fourth season, "The Way of the Warrior". In their place, visual effects coordinator David Takemura led on the visual effects work on both "Rejoined" and "The Visitor".

VisionArt combined these shots with the force field and footage of the engineering set on board the Defiant, while a staff animator added a "plasma glow" around her feet as she made contact with the field.

Farrell praised Thompson's part in "Rejoined", calling her a "wonderful actress and a joy to work with". Themes Writers on Deep Space Nine had previously hinted at a potential same-sex relationship in the first season episode "Dax", when Jadzia Dax says goodbye to Enina Tandro, a former
