The episode is named after the Otis Redding song "You Don't Miss Your Water", that plays an important part in the episode.
The homecoming scene is actually a six minute one shot unbroken take.
Peter Mullan (The Broker) & Lindsay Ayliffe (Mr Stout) also worked together on Ozark (2017) as Jacob Snell & Harry respectively.
While explaining why he won't take The Broker up on his offer Mac tells Arthur that he won't get killed under a car, thus foreshadowing Cliff's death.
