""The first person I ever revealed my identity to was Dick Grayson. He was about the same age I was when my parents were killed. His parents -- circus acrobats -- had been murdered. And I... wanted to make a difference in his life... The way, if my parents had lived, they would have made a difference in mine... Through the years, I've debated whether it was fair of me to take him in. Train him. Give him another identity to hide behind. But, I've learned that Dick wasn't like me. He didn't come from a world of privilege. He was a performer. Gifted in that way. And while, at the time, the transition from Robin to Nightwing was... difficult for us both -- it was a day I had long prepared myself for because... Dick was born to be in the center ring." - Batman (Batman #615, 2003; Jeph Loeb)."
