Quark's speech about Ferengi values and how "the line must be drawn here; this far, no further" was a deliberate tribute to Patrick Stewart's in Star Trek: First Contact (1996).
In a deleted scene, Garak, Damar and Kira get drunk in Tain's basement.
This is the only episode of the series in which Jeffrey Combs plays both of his major recurring characters, the Ferengi liquidator Brunt and the Vorta administrator Weyoun. On two occasions, he does so in consecutive scenes. It should be noted that the characters never met on screen.
Ron Moore has stated the original intent was to rename USS São Paulo the USS Defiant-A but, budget constraints meant it would cost too much to create new footage of the ship with the A. Stock footage of the first Defiant were ultimately used without the A.
Like Avery Brooks, Patrick Stewart also directed the penultimate episode of his series, Star Trek: The Next Generation; "Preemptive Strike".
