The moment when the letters "Atlanta" appear on pieces of meat in a butcher window at the beginning of the episode might be a reference to the credits of the movie Delicatessen by Jean-Pierre Jeunet and Marc Caro. Amélie, another movie by Jean Pierre Jeunet, is mentioned by Van later in the episode.
Besides having a facility for the German language in a previous episode, Helen (2018), Zazie Beetz demonstrates a good command of French as well. The actress was named after the main character of the film "Zazie dans le métro", a French movie which, like this episode, is set in Paris.
Xosha Roquemore, featured in this episode, is the mother to the first child of LaKeith Stanfield, who plays Darius throughout the series.
Banlieue (pronounced BAN-LEW) is the outer suburb of a major Metropolitan city in France which is composed of subsidized housing developments (called cités) designed for lower-income communities, and it typically houses migrants and guest workers. These districts tend to have a reputation for crime and a state of disrepair, and its residents have trouble finding gainful employment, the moment their home address is listed on a job application. In English, these areas would be referred to as : Housing Projects, Housing Estates, Slums, or even No-Go zones.
