Luke's field assistance to Ryan Wilder using the electric weapon stolen earlier might be a possible reference to his role as Batwing in the comics.
Horten Spence makes his debut this episode. In the comics, Spence was a photojournalist for Gothamite News who partnered with Vicki Vale.
Vesper calls Spence "Batwoman's Lois Lane", referencing the journalist character from Superman media, who appeared in season one's crossover Crisis on Infinite Earths: Part Two (2019).
About Enigma counseling Jacob, Caroline Dries quoted "In that moment, I would say Enigma as Evelyn Rhyme is just being a therapist," says Dries, explaining why she gave him actually good advice. "Enigma has her hand in all the cookie jars and good for her but it's going to get her in trouble but at the end of the day, she's a world renowned psychologist and psychoanalyst. So she knows what she's talking about, so I believe that was genuine therapy, that was genuine advice in that moment, and she didn't know the consequences of that."
Luke jokes that Black Mask could blame anyone for the loss of his daughter, name-dropping Aquaman.
