During Dr. Carver's montage of speaking with Arkham inmates, the Riddler calls her "my deer girl." Typo? Or is Riddler aware that "Dr. Carver" is actually Jane DOE?
Trying the Insanity Defense in Gotham is insane, because if the jury buys it you are sent at Arkham with Joker and all the other monsters. That is why the jury accepted Warren's plea: he was clearly insane doing it there.
The Running Gag of psychopaths of Arkham and literal demons from Hell itself declaring Warren is "the worst man [they've] ever met" seems incredibly silly considering that fraud and embezzling money is Poke the Poodle compared to what they do on a regular basis. But the Arkham maniacs have the (very minuscule) excuse of being insane and the demons have the (again, very minuscule) excuse of being residents of Hell and arguably being Made of Evil. Warren, on the other hand, doesn't even have that, being a 100% sane (at first) regular human. And for the demons in particular, according to The Divine Comedy, those guilty of fraud will be condemned deeper in Hell than those guilty of murder.
Once you learn what Doodlebug's paint is made of, that scene from his prior escape, while initially little more than weird, becomes absolutely terrifying.
The inmates that are original to this story; they're not big names like Joker or Two Face, but they are just as horrifying. Death Rattle and Jane Doe are just examples of what a regular inmate is for Arkham Asylum. Now, think of how many times there's a breakout, allowing murderers like them — who don't have any fixation with fighting Batman — to unleash their mayhem.
