Okay I thought I had watched most if not all of Season 4 but I decided to start through the episodes tonight to be sure I have seen them all and I started with 4x02 because I knew I had most certainly seen 4x01.
Anyway at first I was uncertain of the ending and I honestly wasn't sure whether or not House had told NASA about POTW's condition, especially after listening to his conversation with Cameron at the end. He let the patient believe he had told them but actually didn't and I loved Cameron's theory as to why he didn't really tell them because it ascribes to the fact that House does indeed have a decent side and I love it because it means he got caught displaying it.
