Re: Could the Joker and Bane work together?
I like the idea of Bane keeping the Arkham inmates in Arkham and blowing the access to the Asylum. Then he throws Batman in there after breaking him, and the Pit scenes are Bruce surviving an Arkham Asylum-esque scenario with Joker and Scarecrow plus the inmates. His recovery can be something to fight for, since he'd need to find a safe place to barricade himself.
Don't let the death of the three horses be in vain-see The Hobbit: An Unexpected Journey.
