One of the people singing Christmas carols is Shameless actress Emmy Rossum, who is married to Sam Esmail, the shows director.
The surname of the lawyer portrayed by Jake Busey, Lomax, is a nod to the character Kevin Lomax in the movie "The Devil's Advocate." It could also be a nod to Jake Busey's father, Gary Busey's character Eddie Lomax in the movie, "The Firm".
Mr. Robot says to Freddy Lomax "stop looking around like you're a coked up Henry Hill." This is a reference to Ray Liotta's real life character in the movie Goodfellas (1990).
This will be the final season.
This episode is dedicated to Steve Golin. Golin was an Oscar winning producer, and an Executive Producer of Mr. Robot. He died on April 21, 2019 of Ewing's sarcoma.
