Part 2 Cuckoo's Nest

In part two of "One Flew Over the Cuckoo's Nest", we start to see a clearer picture of McMurphy. His file is revealed and we discover the charges and accusations against him and that another doctor has diagnosed that McMurphy could be a psychopath. It is interesting to see how his character shifts throughout this section of the book as well as the entire book. Here we are introduced to a more calm and relaxed side of him. It is encouraged by his want of getting out there faster, but it also a result of him showing more of a deeper care for those around him as he gets to know them.
At one point, he is extremely quiet while he sits by himself because he is so confused and sad for the younger guys in the ward after finding out that they are there as voluntary patients. They are not committed like him. So at any time they feel ready to leave they can. They just will not because they claim they do not have the courage or the 'guts' to survive in the Outside World. At this point, it seems McMurphy would give anyting to trade places with them.
At the beginning of part two, a meeting is called by Nurse Ratched concerning McMurphy's behavior. With the Doctor present, they talk about what might be best for the ward. Should McMurphy be sent up to Disturbed or not? Everyone agrees that he should, and even Nurse Ratched at one point. But all of sudden she's not so sure. I wonder what made her change her mind? Was it that she didn't want to make it seem as though she gave up and was unable to get him to follow orders, and she would keep him down here until she had won her battle with him? Or was it that she knows he may not be a psychopath or that he is not uncontrolably dangerous? I get the sense that it is a bit of both.
