Passionate Woman at fundraising party

This woman was in Bruce Wayne's bedroom at the fundraising party, with her middle-aged boyfriend.

They were apparently in bed together when the sound of gunfire from downstairs from The Joker startled them into getting dressed. As Bruce walked through the room and entered the Batcave, she was relieved that Bruce had a hidden "panic room" in the wall. She prepared to follow him along with her lover, but the door had closed before they could even approach, much to her disgust.
