well we do get a glimpse of the actual two face (at the end he's wearing the split suit) but i think it could get even crazier, like introduce Harley Quinn as his psychiatrist and have her talk about her affairs with the Joker and have those two cause all the havoc
after seeing Heath's portrayal of the Joker i still cannot believe he died after such a masterful acting job
Except Joker kinda fucked up by saying that everyone would blow up at 12. He should've said that if neither one presses it by 12, they walk away, but if both press it, everyone dies.
