This has been nagging at me since last night. I hadn't watched 'The Mark of Gideon' in a long time and it was one of the episodes that I had seen the least number of times over the years. I thought I remembered how it ended, but I was way off, so what I am remembering must come from a different story....somewhere:
Captain Kirk was in a short but deeply heartfelt relationship with a woman who then died. It affected him so deeply that Spock and McCoy got together and decided that the best thing to do was to use the Vulcan mind meld to erase all memory of her from Kirk's mind....at a time when Kirk would not be aware of what Spock was doing. And they would also take the step of altering the Enterprise's memory banks as well, to remove all trace of her so that Kirk would not find out anything about her by accident.
At the time, I recall thinking that such a plan on their part seemed out of character and quite a stretch. And it also didn't seem all that likely that Kirk would suddenly more or less fall to pieces after having made it through other personal tragedies in reasonably good shape.
I know this was not 'The Paradise Syndrome' or 'The City on the Edge of Forever' and the more I think about it, the more I feel that it may have been in one of the novels or short stories.
Does it ring a bell with anyone?
