Why does John’s presence cause such disorder?

The Director's predicament in the chapter is an example of irony. The Director enters the room with a high regard for social programming and belief in the good of science, state regulation, and conformity in all social practices. However, the Director becomes the chief example of non-conformity when the others learn that he himself exhibited the most embarrassing behavior in society by fathering a child. The Director, who is normally responsible for the creation of life and ordering of class, is also responsible for a sexual act that goes against this dystopian society.
