Batman and the Flash have a whole lot in common behind the mask. They've both experienced loss, know forensic science, and are both a bit introverted. In 'Flashpoint,' Thomas Wayne thinks Barry is crazy, but Barry thinks Thomas is crazy. It'll be really fun seeing those two trying to figure things out.

I really explored self-awareness and emotions through 'Green Lantern.' It might sound goofy, but I do believe that emotions have power. We're all driven by something, and most of that is emotional reaction. For me, it was about recognizing my self-awareness.

I tend to like writing long stories in comics. I worked on 'Flash,' 'Teen Titans' and 'JSA' for years. I always like diving into characters.

The truth is, we're all cyborgs with cell phones and online identities.
