This case was a...peculiar case for Booth and Bones, the victim was into puppy play which confused and disturbed Booth who was a straight laced Roman catholic who thought any kink was morally wrong. And they had to have one of the victims friends called Stefan help them throughout the case and while Bones was fascinated and was asking genuine, anthropological questions Booth was constantly uneasy trying to reconcile his Catholic values with his growing attraction to a man and a man who liked acting like a dog no less. At the end of the investigation they found the victim fraternising with a new handler with the old handler finding out and killing him out of jealousy.
