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?

The thing with Superman is that he's completely emotionally open to the reader. Meaning what he tells you is what he's feeling; there's a transparency there. And what he tells other characters is usually as transparent as can be. What he says he believes in. So there's an honesty that is both really inspiring writing the character. One thing I love about Clark Kent is that there is a badassery that you don't see a lot. Even as Superman, he's always kind of restraining himself. When you challenge him, I think there's nobody that has a stronger spine than Superman.

Does it matter how long they were together that night? To lovers, an hour can last a century. But even for lovers, every hour ends.

It's one of the worst nightmare situations we could create for a young character, having the people who are supposed to believe in you keep telling you you're nothing.

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.

If I know what something's about, and I can always have that touchstone, I feel like I can reach for really ridiculous humor and also go really dark in terms of the things I'm afraid of.
