what she says: i’m fine
what she means: in Star Trek II: The Wrath of Khan, spock performs a mindmeld with dr. mccoy, depositing his katra, or soul, into the latter’s mind. the katra transfers at the moment of the mind-meld rather than at the point of the original holder’s death. spock gives mccoy his katra before he enters the radiation chamber. when kirk arrives to the scene, spock asks him ‘ship… out of danger?’ to which kirk assures him that all are safe. then spock tells him ‘i have been and always shall be your friend’ and dies. in Star Trek III: The Search for Spock, once spock’s katra is reintegrated with his body, he approaches kirk and asks him ‘ship… out of danger?’ again, clearly not remembering any of the events after he placed his katra in mccoy’s mind. however, soon after, he tells kirk ‘i have been and ever shall be your friend,’ a clear echo of his previous ‘i have been and always shall be your friend,’ which he should not be able to remember. there is no in-universe explanation for this, UNLESS kirk was thinking of spock’s death and how he said ‘i have been and always shall be your friend’ and those thoughts transferred through a vulcan marital bond to spock’s mind, in which case spock’s vocalisation of those thoughts, which was said in a questioning manner, could have been a test to see if their marriage bond were still in place.
