One of the things which is most intriguing about 'The Galileo Seven' is the way it splits up Spock and Kirk, but (almost uniquely for TOS) it leaves Kirk on the Enterprise bridge dealing with the bureaucratic nonsense instead of being the one down on the planet in the thick of things.
It also put Scotty in the role of being the balance between passion (McCoy) and reason (Spock). Unlike Kirk, though, Scotty isn't in charge. This is how engineers often see the world. The crew is carrying on irrationally about Spock not understanding their feelings. Spock seems dogmatic about his logical view of life and oddly unable to deal with irrational people. Spock just focuses on fixing the shuttle.
