Carter looked back over his shoulder and was very pleased by what he saw there. Dinah. Arrived and looking gorgeous. The dress was shorter, but that only made sense with the weather. He turned his body to her, and offered his arm as he gave her a nod.
"It's good to see you, Dinah." If it bothered him that she was a little late, he did not show it in the least.
He held the door open so that she could go inside before him. Once inside he led her through the throng of Gotham elite. It kind of surprised him how many of them he knew from his various lectures and work through the museum, and as he walked in he made all the appropriate introductions.
When they reached their table, he pulled out her chair and waited until she took a seat before moving around to find his own.
