Superman: We’re going to bury all of them, y’know. Everyone on Earth. Everyone we know. Everyone we love. They’re going to die and we’re just got to go on. It scares me so much. They’re all a part of me. A bit of me dies with each of them. What happens to a man like me… When my grief outweighs my humanity? What happens when it’s easier to feel nothing than… this. What do I become?
