Re: Stuff you like to believe happened in Nolan's series
I like to think that Joker was taken into federal custody after TDK. It makes more sense than him being the only patient in Arkham. I like to think Gotham is a level of Limbo and all the characters are facets of Cobb's personality at different stages in his life.
"..the mere intimation that there might be more to a heroic narrative than the heroes are the Good Guys, the villains are Bad Guys and the heroes should Win a rousing Victory appears to be in itself such an offensive contention that it arouses a kind of defensive knee-jerk hysteria just by surfacing." - Richard K Morgan
