I think, at the end of part one, McMurphy has the upper hand. When she reads his history out loud, he explains himself. The others seem to find it funny and look up to him when he does this. He even gets Hardings to agree that she is a horrible women. Having all these people on his side definitely makes him seem like he has the upper hand even though Big Nurse has alot of control. I can't rely on Chief that much because I think his view on things and how he tells the story can be misleading or over exaggerated. He doesn't seem very important at the moment. Chief has become more interested and involved (as best as he can be) with the rebellion against Big Nurse with the arrival of McMurphy. At this point, I am rooting for McMurphy. He interests me and Big Nurse is mean and awful seeming and it makes you not want to root for her.
