The scene in which Quark meets Nava is a homage to the opening scene of the film. Like Vito Corleone, Quark scratches his ear, pets an animal and sits in front of a window with Venetian blinds while someone asks for his help. Quark expresses his reservations regarding Nava's previous lack of loyalty in the same way as Don Corleone does regarding Bonasera.
At the end of the episode Quark tells Rom that he is going to reward him for his treachery by promoting him to Assistant Manager for Policy and Clientele, which Quarks admits he just made up. In Star Trek: Deep Space Nine: A Call to Arms Rom stays on board the station after the Dominion takes possession of it, working as a spy for Star Fleet. He tells Quark that he reporting for duty as the Assistant Manager for Policy and Clientele, which he is using as his cover.
