Hey. I've seen a lot of moaning about joker leaving Harley in the car to drown. Imo they have it all wrong. They were being chased by Bats who is FAMOUS universally (literally) for NOT killing. When they crashed Harley was clearly alive. She had a knife ready to attack bats. So joker left because if they are both caught they can't rescue the other. He knew she was 1. Alive 2. Armed 3 would be rescued. He was so upset later after realising she wasn't in Arkham where she was supposed to be. 1/2
GOD BLESS YOU,ANON!I think the main thing why peope think this, is because the scene was cut. This scene somewhere in the world exists in extended version and I am sure that extended version show us something more about it. Your view of the thing is very similiar to mine. He left her there, because he knew she was okay and that she will kick bat’s ass (which unfortuntely didn’t come by the plan a bit). But of course he right after that wanted to rescue her.
