Aww I feel like crying too batman... and I totally agree with that, the end of the games story, just ugh, I've thought of alot of different ways it could end myself, carried on the story in my head, but nothing like this, I'm so glad i found this. Joker and batman complete each other in a weird way and you seem to describe it perfectly.
I just couldnt help it after being filled with so many feels for Batman and Joker at the end of the story. It's just too much for someone to let go, as specially if they fel the need to write it all out. Hahaha.
