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.

[Duke] is the same way that Harper Row is a character who doesn't want to know who you are beneath the mask, and that makes her interesting. She'll show up and help Batman, but she never wants to know if he's Bruce Wayne.

I love The End of the Batman story. I have my original copy, the hardcover, at my house from when I was a kid, whenever that was,'88 or '89. It was very influential to me because it was so explicit in touching on the notion that Batman might be mad and that he might belong in the mad house.
