Cass will be rather interested in this 'Batwoman' when she eventually shows up. Wonder if the two of 'em will get along in costume.
Any friend of Dick's is a friend of hers, as far as Cass is concerned. We'll have to figure out how much Babs is aware of Cassandra, since she has a peripheral involvement in the Wayne family, being Leslie Thompkins' daughter figure. And she teaches awesome self-defense at the Park Row Clinic & Community Center, so there is that.
