well when i was watching Amok Time again I realized that this whole friendship angle was maybe not as one-sided as it first appeared to me because it's set up very quickly so you can miss it but T'Pau says that Spock is basically dead to the world because of "blood fever" and so Kirk won't be able to talk to him. but he actually does through sheer force of will manage to snap out of it to beg T'Pau (eloquently) to make an exception and not make Kirk fight. even she is surprised he's able to speak at all.
