"I'd love to be your redemption, but I am just a man. I may never be a hero, but I'm a rock you can lean on."
She saved him, in so many ways had she saved him. She'd physically saved him from a gruesome fate many times. She'd saved his sanity more times than he could count. And she'd saved his heart. He had vowed never to let anyone close, not wanting to feel the same pain he felt when his parents were taken from him. Above all, he wanted to be the one to save her, and he had. He may have been a mere mortal, but he would gladly go to hell and back if that's what she asked, if that's what he needed. Not that she would ever ask him that, but that's how deep his devotion to her ran. He knew as Batman he was a symbol, for justice, for hope. But he was mortal, fragile compared to her, and wasn't looked on very fondly as a hero. Just a vigilante, but he was the vigilante who had captured her heart, and he intended to keep it that way for as long as he possibly could. He'd show her how much he loved her, or he'd die trying.
