What is it about the Flash, as a fan and storyteller, that has kept you coming back for more and to hold him in such high regard? You've gotten the chance to write Barry Allen and Wally West and Jay Garrick with the JSA. One last question, Geoff: The Flash celebrates his 750th issue this month and you've said multiple times that he's your favorite superhero. To me, if you look at it in a very base level, you look at these characters and they've reacted extremely differently to events that have befallen them. They're all driven by grief and trauma and I think they each kind of personify something different there. In a way, I feel like the Bat Family symbolizes the Kubler-Ross Five Stages of Grief.

We've never seen a story that's focused - really, really focused - on these three specific characters and the pain that the Joker's caused them.

There are scenes between Bruce and Barbara and Barbara and Jason and Jason and Bruce that we've never seen. He has kind of both chaotic and specific motive in Three Jokers and we'll see that unfold in the prestige-format series. But it explores a lot of different facets of the Joker and of the Batman family and how these intersections have wounded it and how they evolved from that and what the Joker's ongoing mission is. You know, there's not a lot of Batman stories that are mysteries or detective stories and we really wanted to tell a detective story. And it just developed into this story idea that was going to explore, in a lot of ways, the pain that the Joker's caused, the healing and that process that results from it a different mental state for the Joker is something we're going to dive into, a mystery. Geoff Johns: This story came out of conversations between Jay Fabok and I about the Joker and the nature of his character and history and what he's done to Batman and his family and what he continues to do and how Batman responds, how Barbara dealt with it, how Jason Todd's dealt with it. You had written the Joker in a supporting capacity in books like Doomsday Clock before but how has it been putting the Clown Prince of Crime in the spotlight? The last time you and I spoke, you said Jason was in the middle of wrapping up Three Jokers.
