How does chapter twenty-three clarify the conflict of the nevel?

Manipulation and control are the themes here. The other patients calm Billy as the patients return to the ward. Chief Bromden walks beside McMurphy and can tell that he is afflicted with some great worry. McMurphy asks Sam, one of the boys, if he can stop by the canteen to get cigarettes. At the canteen, McMurphy buys several cartons. During the meeting that afternoon, Nurse Ratched brings up their behavior several weeks ago. She claims that she waited too long to deal with it and give the men a chance to apologize. She claims that her discipline now is entirely for their own good. She is taking away tub room privileges. McMurphy says nothing. He stands up and walks with his normal swagger to the Nurses’ Station and punches the glass in order to get his cigarettes. He sarcastically says that the glass was so clean that he completely forgot it was there.
