In one of the biggest spoilers we've seen to date , The Joker was seen being hauled away in the back of a police cruiser while laughing like a maniac. In all honesty, this could be something which happens at the halfway point but it's hard not to wonder if these shots could ultimately be from the final act as the cops finally catch up to Gotham City's new Clown Prince of Crime.We'll have to wait and see but I don't think the plot will be as simple as The Joker being arrested and being made to pay for his crimes! My guess is he's the one who kills Thomas and Martha...
