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.

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

What Batman is saying is that, "I want to try something new that's more about this era and this moment." And I do think that it speaks to a modern take [as opposed] to a 90s take or a 2000s take being maybe the older program about having a sidekick.

I always, always got to be the last man standing.

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?

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

You take the thing that is the worst thing that could have happened to you, the worst challenge in your life, and you turn it into fuel. You don't give up. And that's what Gotham is about.
