Chief Bromden, change in character?

Chief Bromden, is the narrator of One Flew Over the Cuckoos Nest and begins as mostly an observer. Chief then begins to change as the story developes and begins to release his potential power he gained through being an observer. Cheif begins a transformation from "deaf and dumb", "small", quiet, and coward like to courageous and big. How did Chief release this potential energy?

Chief begins the story as a scared observer, who plays out to be "deaf and dumb". As the staff members, including Miss Ratched and the black boys, know this they allow him to clean during there meetings. This then gives Chief the potential advantage as he learns all the secrets, but he is still too belittled to use his power.

Chiefs advantage is not soley informational, but also physical as he is described by McMurphy. McMurphy tries his best to make friends with Chief and talks to him. One day Chief replys and begins to warn McMurphy, because he cares for him. Chief grows as a more dynamic and active part of the acute community, going so far as to defend one. As Chief and McMurphy are sent to disturbed Chief becomes stronger, and more courageous as McMurphy trains him. McMurphy helps Chief change into a more outgoing character, who transforms his potential energy to kinetic.
