I actually wonder if a smarter way to handle Arkham nowadays to avoid all sorts of negative stereotypes and cliches about mental health and criminality/violence might be put the Asylum early in Batman’s career only, and have Strange go “Monster Men” on some of the inmates to justify keeping them there, with Crane’s help.
Incidentally, my preferred idea for Magpie would be to have her be Strange’s attempt to replicate Catwoman, with Magpie’s far more blatant kleptomania and screwed up approach to her sexuality being terrifying signs of what Strange thought goes into Selina.
