Dinah had felt someone enter the room, and had spotted Zee out of the corner of her eye. So she wasn't startled by her friend's presence. She looked up and swept some of the hair that had come loose from her ponytail out of her eyes and grinned.
"Not exactly a who. It's more of a general frustration," she said with a smile.
She took her ponytail out and then retied it and went over to get a drink of water.
"How are you doing, Zee?" she asked.
She knew that Zatanna considered the mayor a friend and she could only guess how hard she was taking this. Dinah was taking it hard herself, and she'd only just briefly met Jack a few times.
