I really wanted to make sure that if we set Duke up, that he's set up the right way and he's his own hero for the right reasons.

The hope that they have legs. That's the biggest fear you always have creating new people. You love them, but then they kind of dissipate. Sometimes you don't get to write them as much as you'd like, like me and Harper Row.

[Duke] is the same way that Harper Row is a character who doesn't want to know who you are beneath the mask, and that makes her interesting. She'll show up and help Batman, but she never wants to know if he's Bruce Wayne.

Having that North Star for every story [about Batman] is really key for me. It allows me to go farther and farther off the reservation.

There's nothing comparative to Damien [the current Robin] or any of the other characters. I love those characters. And this isn't, "This is better than that." I think a couple of people misread what we had said in the first issue about that stuff.

I think thing that makes Batman so endlessly interesting is that he's one of the most flawed and deeply human characters, even though he seems completely the most inhuman and infallible in costume. Psychologically he's one of the most complicated in both his strengths and his weaknesses. For me, one of his great strengths and weaknesses is that confidence. His emotional self-protection is one of the things that makes him heroic and sacrificing; he doesn't have a personal life. He sacrifices those to be the best hero he can be.

This one's like that because it's about these things that I think weigh heavily on me in terms of my own failings and the things that I worry about and my personal demons. Is the sum of my personal demons greater than the things that I like about myself? Is this moment - because it's a particulary high tension, scary moment for all of us in terms of the global climate - going to bring out the best or the worst in us?
