well aware that this is common knowledge but it'll always kill me that bruces grief will last forever. Batman is a concept, a character in a comic book and because of the nature of comic books lasting for like ever he's going to repeat the same plots and learn the same lessons over and over and over. Closure quite literally doesn't exist for Bruce Wayne because he'll be in that alley for eternity, he'll keep holding his kids in his arms as they die and failing to save people for eternity. Concepts are eternal, batman is eternal. His grief will last forever.
