* A flashback to the Waynes' murders has Thomas tell Bruce that someone like Zorro would be locked up in Arkham, something that was also seen in ''ComicBook/GrantMorrisonsBatman'', which retconned that "Zur-En-Arrh" wasn't the name of an alien planet, but a corruption of some of Thomas's last words, "Zorro in Arkham". [[spoiler:Some of the Red Hood endings have Jason facing down the "Batman of Zur-En-Arrh".]]

* In one timeline, Batman talks to [[spoiler: {{Franchise/Superman}} [[WebAnimation/HowItShouldHaveEnded in a cafe]]]].

* The mere concept of Jason becoming either Hush or Red Robin. Originally, Hush was supposed to be Jason himself [[note]]and sort of was, in that later issues revealed that Bruce initially ''had'' been facing him in the graveyard scene[[/note]], with Thomas Elliot being a RedHerring SacrificialLamb, but editorial got cold feet and vetoed the idea, giving way to Tommy Elliot being Hush. As for Red Robin, Jason took up that specific identity during the events of ''ComicBook/CountdownToFinalCrisis''.

** The use of [[spoiler:flashbacks that are only black, white, and red in the "Batman dies and Jason still becomes Red Hood" route evoke those in both the special edition of ''ComicBook/TheKillingJoke'' and [[WesternAnimation/BatmanTheKillingJoke its animated adaptation]].]]

* The Joker [[spoiler:giving up on crime after killing Batman and adopting a civilian identity]] is probably a reference to the 90's story arc Batman: Going Sane. In which [[spoiler:the Joker does the same after seemly killing Batman. Although the comic's story was played up more tragically, with the Joker not remembering his past and trying to live a normal life while dealing with his psychosis until Batman's return drives him mad again. Here he's completely aware of his past actions and seemly only quit being the Joker to avoid repercussions and because without Batman the game was boring. Additionally how Batman dies in this route is quite similar to how he dies in the Going Sane story, getting caught in an explosion in a rigged warehouse, albeit Batman survived in that story]].

** [[spoiler:Right before Joker dies, he wipes his disguise facepaint off, revealing his true face underneath. This seems to reference Film/Batman1989, where Vicki Vale splashes Joker with water and washing off his guise.]]
