- Actor Allusion:
- This isn't the first time Troy Baker and Laura Bailey have been Ship Teased.
- Nor is it the second.
- This isn't the first time that Steve Blum has voiced the leader of a revolution in a corrupt city either, nor the first time he's voiced the secret identity of a masked villain.
- Beam Me Up, Scotty!: Alfred is accused of forcing a sadistic choice on Bruce on whether to remain Batman or retire so Alfred will stay, despite the fact Alfred never actually makes Bruce choose. The closest Alfred actually gets to actually doing that is merely mentioning that Bruce can do good in other ways besides being Batman and even mentions he believes that Bruce would never give up the crusade. It's BRUCE himself who makes this decision and if he gives up being Batman, Alfred himself will be surprised at what Bruce is considering.
- Casting Gag: Troy Baker voicing Bruce Wayne this time around has to be intentional, considering he previously voiced Two-Face, The Joker, Tim Drake and Jason Todd, and Dick Grayson.
- Fake Brit:
- Subverted. American Jason Spisak as Oswald Cobblepot, who much like The Penguin in the Arkham games is from Gotham, but was raised in England.
- Another possible subversion (or perhaps inversion) in Riddler's case. He's voiced by Robin Atkin Downes, who uses an Americanized version of his normal London accent, yet his regular accent sometimes slips through. This version of the Riddler is established as an international terrorist, however, so this may be him picking up an accent from his travels.
- Fake Nationality: Once again, we have French-British JB Blanc voicing South American Bane.
- Meme Acknowledgement: The [Grapple Away] choice from the first season reappears in The Enemy Within, mostly because the developers noticed how much it amused Matt and Woolie from Two Best Friends Play.
- The Other Darrin: Renee Montoya's voice actress changed from Krizia Bajos to Sumalee Montano in season two.
- Playing Against Type: Erin Yvette has made a name for herself in playing heroic female characters in adventure games, such as Snow White in The Wolf Among Us, Sasha from Tales from the Borderlands, and Alex in Oxenfree. This makes her reveal as the psychopathic Big Bad Lady Arkham sting even more.
- Production Posse: Standard operating procedure for Telltale. The leading trio from Tales from the Borderlands, Rhys (Troy Baker), Fiona (Laura Bailey) and Sasha (Erin Yvette), return as Batman, Catwoman and Vicki Vale, respectively. In fact, Erin Yvette has worked with Telltale for a long time, previously as Snow White in The Wolf Among Us and Bonnie in The Walking Dead.
- Promoted Fanboy: As Anthony Ingruber reveals in a Season 2 featurette, though he was already an established voice actor, his impressions of Heath Ledger and Mark Hamill's Jokers on YouTube were what prompted Telltale to cast him and encourage him to put his own spin on the character.
- Real-Life Relative: Harvey Dent and Selina Kyle/Catwoman's voice actors are also a married couple in real life. Bruce's voice actor (Troy Baker) is Willingham's best friend, and was their Best Man at the wedding.
- Role Reprise:
- Schedule Slip: The release on Seventh Generation consoles was delayed to a tentative "Later in August", after Episode 1 came out on August 2nd for PC and Eighth Generation consoles. The episode failed to arrive on the Seventh Generation consoles before September 14th, the same day as the release of the final episode of Minecraft: Story Mode.
- What Could Have Been: According to Kent Mudle on his Tumblr, Iman Avesta was originally going to be a romantic interest — as indicated by her blatant crush on Batman. However, this was ultimately scrapped.
- Word of Bi: Kent Mudle confirmed on his tumblr page that John is bisexual and interested in both Harley and Bruce (with a slight preference for Bruce). He says John would be thrilled if he could convince both of them to have some sort of three-way relationship.
