Crowley and Dan
The demon could see the confusion the man's face. He brushed it off. Humans were constantly confused. It was their thing. Interesting and amusing things often followed. Like that one time when deputy chief inspector Roger Karrington had seen a man in a black suit - Crowley, to be specific - walk out of a burning building unsinged. It had certainly confused him. It had also made him have a completely bizarre conversation with another more helpful man - Aziraphale, to be specific - shortly afterwards where he had slowly and steadily talked himself out of ever seeing the man in the black suit at all.
"Crowley," he said and downed the drink in front of him. He tapped next to the empty bottle on the table. "Another one," he shouted to the waitress - owner - whatever. "Been here longer than I want to. I can only say, hell, it's boooooring! Is there even anything to do in a medbay?" Sure, humans got sick all the time but even they spent most times outside of hospital.
