On the emotional side:
- Her father wants to reconcile their differences and Kate isn't ready for that. (It's important to read Batwoman: Elegy first to understand the backstory in Hydrology.)
- Her cousin Bette -- aka Flamebird -- is trying to convince her that she will be a good sidekick.
- Her romantic involvement is with a member of the police force, which increases the danger should her vigilante identity be revealed.
- Two different organizations are attempting to learn Batwoman's civilian identity.
- Children are disappearing from Gotham City.
I loved the La Llarona element, however. Who knew dripping water could hold such menace? Readers with a fear of water might find this story especially scary.
Williams III is also the author, along with co-writer W. Haden Blackman. The story isn't quite as substantial as that in Greg Rucka's Elegy, but Hydrology certainly held my interest. I look forward to future issues.
