Worf's poem to Jadzia in Klingon reads: "Open your gates, Stovokor. Welcome Jadzia to your halls. Welcome this honored warrior. Welcome her, Stovokor, for all eternity."
A few months after this episode aired, the Mojave Desert filming location used for the surface of Tyree was seen again as the surface of a Delta Quadrant class D planet in Gravity (1999), including the Joshua Trees.
This episode features Casey Biggs (Damar) as Dr. Wykoff, continuing the concept of people in Sisko's Benny Russell visions being played by series regulars or recurring guest stars without prosthetic make-up. Also, in a scene with Odo, Nana Visitor (Kira) appears in two closeup shots without her Bajoran nose ridges, as she did in the previous Benny Russell episode, but here this is unintentional, a mistake.
The novel given to Kira by Odo is Mickey Spillane's 1952 Mike Hammer novel Kiss Me Deadly.
Nicole de Boer (Dax) and director Allan Kroeker knew each other very well from the TV series Beyond Reality (1991), where they had shot ten episodes together. Neither was aware however that the other was working on Deep Space Nine until they met on-set on the first day of shooting this episode.
