Whatever she was expecting behind the door, this... wasn't exactly it. Dinah turned her attention to Zoe, the realization hitting her in waves. Her first instinct was to ask if Zoe had somehow taken up the mantle of Batgirl or Batwoman. But there hadn't been a Batgirl or a Batwoman around the City. No, the only hero that was around the City when his alter-ego wasn't was...
"Batman," she said aloud. She looked over at Zoe. "You're... Batman?"
There were a lot of questions as to how, but Dinah had no doubt that it was possible. It was actually a pretty brilliant ruse, really. Who would ever guess that anyone besides Bruce was behind the mask? And if they did, no one would suspect a woman. Not even one who seemed to be close to Alfred and important at Wayne Enterprises.
