I am sitting and watching Batman:Mystery of the Batwoman for the twenth time with my boys at the moment. And I been meaning to track this done and find out when this devolped.
In the beginning of the movie Barbara and Bruce had a brief phone converstion,
It was implied that they had either startted a relationship/flirtation with each other. But my question is: Was this a one time character devolpment, or was there a exchange that happened in another story and if so which one?
