Despite the informality of the event and the fact that Herbert didn't rsvp in any way, Herbert is a stiffly formal figure, walking around in his suit with a pencil and notebook out. He doesn't pay any attention to the food, or approach when a crowd gathers around the flashier displays. All he's doing is jotting down notes, occasionally sitting down to write something down faster.

Eventually, he approaches someone the moment they're by themselves.

"Excuse me," he says, and sets his pencil to paper if they turn around. "How would you describe, your magic's methodology, or function?"

This, of course, excludes Foster, who he holds his gaze with briefly but doesn't approach, and Strange, who he looks away from dismissively upon any eye contact.
