After getting into an argument with the librarian after she mistook him for a mad scientist, Dr. White was just leaving the grand library with a book on anatomy under one arm, ready to drown his fustrations in coffee. Yes, he might have been seen around Halloween, but he's not wearing the plague doctor costume at the moment so he might not be recognizable at first.

He made it to the coffee machine when the man who was covered in mud spoke up and got his attention.

"... I have no idea," the doctor admits. He has met two Jim Kirks, but never bothered to get their names. "But here's a better question for you: where have you been? You look like you got a bucket of mud dumped all over you." Gross.
