Completely agreed about Spock's emotional journey. It's also important to note that Spock's relationship with the crew of the Enterprise is far more familial and personal at this time than it is TOS. Look at how Ortegas and Uhura tease him mercilessly on the bridge, and he indulges them with an air of bemusement. I think that by the time he becomes Jim Kirk's first officer, years from now, he will have seen this close-knit group of officers move on one by one... and as friends come and go, he'll adopt a more distanced, some might say more professional attitude, one that he considers befitting of an executive officer.
