"'Maze': Bartender, Bodyguard, Demon???" "'Dr. Canaan': Therapist, Brother?, Angel??", "Church aware of Father Frank's past?" "Mazikeen Smith can't be her real name" "Charlotte Richards: Lover? Sister? Step-Mom? WTF?"
Before Netflix acquired the series, this and the pilot were the only episodes which did not start with "Previously on Lucifer...". Season 4 does not use recaps, instead trusting the audience will be able follow storylines within the binge streaming format.
When Lucifer introduces Reese, he exclaimed, "Ah, owner of the Pieces." He was referring to Reese's Pieces, the candy brand manufactured under The Hershey Company.
