"Son of Gotham" had a lot of Gotham mythology in it, with the Order of St. Dumas finally being officially named in the show (more on that in a moment). There weren't a ton of easter eggs, but a few notable ones, and here's what we caught!
Check out the references and what they mean in the slides that follow, and rate the episode with a click above!
Theo Galavan is locked up in Blackgate Penitentiary at the start of the episode. It's been mentioned and seen a few times before on the show, and as an institution, is straight out of the comics.
An Island Prison in Gotham Bay, Blackgate has typically played host to the dangerous more mob-oriented criminals of Gotham City, while Arkham contains the criminally insane members of Gotham's rogues gallery, though some have swapped between the two. Interestingly, it was also mentioned on The Flash this season, giving the two a very small and tenuous connection.
Order of St. Dumas
We've spoken at length about the Order of St. Dumas before, but this is the first time they've been officially mentioned and named by characters on the show.
The Order, a splinter group of the Knights Templar, eventually has splinter groups of its own. They have had two main warrior titles that have been passed down through the generations: the Dumas and the Azrael. With Theo Galavan displaying considerable fighting skill and calling himself "Dumas," we may be getting a take on that in his character. Characters bearing those titles have been both ally and enemy to Batman.
When interrogated, Silver says that the man who killed Bruce's parents was "Malone. First name started with an M."
This is an obvious reference to Matches Malone, Bruce Wayne's most frequently used alias. He typically uses it to go undercover and talk with the criminal underworld. It was the name of an actual criminal first, though.
In the comics, he had nothing to do with the murder of Thomas and Martha Wayne; he was small-time only, and when he died, became one of Bruce's many weapons in his arsenal as the Batman.
Alfred the Fighter
Bruce Wayne's butler has a past that includes more than just service to the Wayne family. Alfred Pennyworth was also a member of Britain's Secret Intelligence Service.
That's been used in various degrees in the comics. Often, the focus is more on his combat lifesaving skills, rather than his combat training. In the Batman: Earth One graphic novels by DC Entertainment CCO Geoff Johns, though, Alfred gets considerably more hands-on. He's been training Bruce, and now we see why!
Bruce and Selina
Bruce tells Selina in this episode that he has a special bond with her that will never go away. Indeed, for decades and across basically every media and interpretation of the character, Bruce Wayne and Selina Kyle, and likewise Batman and Catwoman, have had an on-again, off-again romantic relationship, but almost always a very close friendship. She understands him and his choices more than most seem to. This alludes to that and implies they'll have a future on Gotham, too.
