Zatanna/Bruce (open to Selina if available!)
Zee was well aware of the differences between Bruce and the real person beneath the mask. Just as she was quite good at the smile that had given her quite a lot of attention when she was starting out. The difference was that Zatanna's smile was usually real where as she knew what lurked beneath Bruce's facade all too well.
"Mr. Wayne, it is a pleasure to see you again." She could play the game just as well as he could, although her smile was definitely genuine when he finally had time to sneak away from being very busy and important to speak with her. "I have to say that I was delighted at the last minute invitation. And you've outdone yourself again tonight with the decor and the spread, even with the storm." And Zee had no problem giving to the charity event given that situation. If anything, it was another incentive to make an appearance just for that.
Zee was quick to tuck her arm into his, taking advantage of their familiarity without hesitation. It was Bruce, after all. "It's good to be back."
