[Bruce] sees a lot of himself in [Batman], you know? You could argue that something even worse than what happened to Bruce happened to [Duke's] parents, who are now Joker-ized*. They're not just gone or irretrievably lost. And I'm NOT curing them, so you can put that out there! There's no relief from that.

First of all, what made him [Duke in "Zero Year"] captivating is this sense of somebody who wants to save the city regardless of whether Batman wants to or not, but has been inspired by Batman. He's always been - not combative with Batman or anything - but I think he has a sense that what Robin is and what heroism is in Gotham is something that's inspired by Batman and sort of separate from Batman.

Duke is a character who believes that heroism and the Robin mantle can exist entirely separate from Batman himself.

Vampires as creatures have evolved over time as different vampire bloodlines have hit different populations of humans. Every once in a while the blood will make something new and mutate into a new species with different powers, abilities, weakness, physical characteristics, and so on. I don't want to give anything away, but there are whole species and branches that date all the way back to pre-modern times.

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.

One of the things that's great is that Batman is a character that lends himself to very personal stories.
