Capt Levara, a Romulan smuggler, was named after LeVar Burton of Star Trek: The Next Generation (1987), director of this particular episode, as a way of getting his name into the show.
This is the first appearance of Elim Garak since the fourth season episode Broken Link (1996) where he was sentenced to six months in prison for sabotage and assaulting Worf. Apparently, this episode is set six months after the aforementioned episode.
This is the first time a character uses the pejorative "spoon heads" in reference to the Cardassians, taken from the resembling design on their foreheads.
This episode was directed by LeVar Burton, who played Geordi La Forge in Star Trek: The Next Generation (1987).
In this episode, Worf refers to "runabout pad 1." In all other episodes, runabout pads are identified by letter, not number.
