McMurphy has certainly had a big impact on the ward even in his short time there so far. He always seems to get around things and likes to have things his own way. He doesn't seem as easily influenced by the Combine as the other patients. For example, one morning McMurphy was the first one up and was going about singing loudly. The other patients were astounded because they hadn't heard singing in so long. Chief was wondering, "[The black boys]...never let anybody raise that much racket before, did they? How come they treat this new guy different" (Kesey 91-92) Then he realized, "...the new guy is different, and the Acutes can see it...He's just as vulnerable, maybe, but the Combine didn't get him" (Kesey 92). This just shows how different McMurphy is from everyone else there. So different, in fact, that Chief notices a new smell that no one else has. He smells of, "...dust and dirt from open fields, and sweat, and work" (Kesey 101). Quite literally, he would smell this way because of where he came from: a work farm. However, this is making a bigger statement and saying rather than the typical ward smells, McMurphy stands out and has retained pieces of himself still. These smells would be appealing to Chief because it would bring back memories from his Indian tribe and would be smells he used to be very familiar with. It would probably bring him comfort.
The Combine is what Chief calls the brainwashing, controlling, meticulous influence of the ward, the staff, and the Big Nurse. He experiences it as if it were a tight organization that is trying to control the patients' every little move, even to the point of controlling their thoughts and the most basic actions. Chief sees through it most of the time and is very aware of the controlling brainwashing that is going on. He sees the way his fellow patients are walked all over and the way McMurphy stands up to the unspoken rules just by being himself. I think McMurphy is aware that the Big Nurse is controlling everyone, but I don't think he tunes into all the little details in the way that Chief does. The other patients (at least the higher functioning ones) may be also aware that they are being strictly controlled and that the Big Nurse has to always get her way, but again, they probably don't realize the full effect of the Combine. For example, something simple like having the toothpaste locked up until a certain time is just a rule the patients are used to. If the Combine can control little things like that it can certainly begin to take over every aspect of the patients' lives. However, McMurphy challenges it. He asks, "What reason you suppose they have for puttin' something as harmless as a little tube of toothpaste under lock and key" (Kesey 93). He starts mocking one of the black boys about how people would be brushing their teeth whenever the spirit moved them and they (the Combine) wouldn't want that. He says, "And, lordy, can you imagine? Teeth bein' brushed at six-thirty, six-twenty - who can tell? maybe even six o'clock. Yeah, I can see your point" (Kesey 94). This to me proves that McMurphy is more aware of the Combine than the other patients because he realizes what they're trying to control just for the sake of having power. I feel like the other patients have gotten so used to the rules that even if they know in the back of their minds that some of it isn't right, they just move on and live their life almost indifferently each day.
