The homecoming scene is actually a six minute one shot unbroken take.
The episode is named after the Otis Redding song "You Don't Miss Your Water", that plays an important part in the episode.
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.
