This episode marks the directorial debut of Andrew J. Robinson (Elim Garak). Unfortunately, this is the only episode of Star Trek: Deep Space Nine that he would directo. He would go on to direct two episodes of Star Trek: Voyager.
When Jadzia is talking to Worf in Ops, she mentions that to the best of her knowledge the time on Qo'noS was the last time that Quark saw Grilka. When she says this, the camera is showing her hands on her hips. As she finishes her sentence, she crosses her arms. In the next shot, from her right side, her right arm is positioned so that her hand would again be on her hip (farther away from her torso and arched slightly behind her body) even though there was no break in the scene for her to shift from her arms being crossed. In the next shot, while continuing to talk to Worf, the camera shows her from the front again with her hands crossed.
It has been readily apparant since their first meeting in "The Way of the Warrior", all the "battles" that they partook of in the holosuite, and other moments spent together that Jadzia had feelings for Worf. Her quote to Worf when they first met in the aforementioned episode, "Louk, a jeek CHIM-ta law" ("Yeah, but I'm a lot better looking than [Curzon] was.") and Jadzia's initial sparring match with Worf in the holosuite a while later would eventually lead to the events in this episode.
