McMurphy, Chief, and Cheswick are taken to another ward in the hospital. A nurse comes by and gives pills to each of them. Then she asks Mr. Cheswick to follow her. Cheswick screams as some orderlies lead him away.
McMurphy is left alone with Chief, and he offers the guy a stick of Juicy Fruit. He thinks he hears Chief say, "Thank You," so he offers another stick.
The second time, Chief clearly reads out the name "Juicy Fruit."
At this moment, McMurphy realizes that Chief has been faking his deafness the entire time. He just does it to be invisible to people.
McMurphy is insanely happy to find out that Chief has fooled everyone so badly.
He tells Chief that the two of them need to escape. Chief thinks Canada as the place to go.
Some orderlies come out with a stretcher and wheel an unconscious Cheswick past them. We don't know what's happened to Cheswick, but it doesn't look good.
The nurse from earlier comes out and asks McMurphy to follow her.
A team lays McMurphy on a white table and gives him electroshock therapy.
