...a general outline of the events of the period between TMP and TWOK...
As noted earlier, respectfully:
WHAT period between
TMP and
TWOK?
By internal evidence of the movies - leaving aside all comment or suggestion by or about the people who made and marketed the films, who decided to remove or replace the II in the title of
TWOK, etc., more than a generation ago - there is nothing to suggest any continuity between the two stories, other than the reuse of a little footage of spaceship models. All else is inference about the intent of Paramount, Meyer, et al. Of course the passage of time (as indicated by changes in uniforms, set decor, Kirk at a desk job again, etc.) is explicitly part of the story of
TWOK, but
there is no evidence to suggest this was time elapsed since TMP (rather than since the end of the original mission). I am sympathetic with the idea of Spock having evolved since what happened to him in
TMP, but he could have loosened up for other reasons.
Obviously people write, sell, and buy novels set in the period "between"
TMP and
TWOK. But to me that would be like trying to reconcile the two
Doc Martin TV movies with the series that followed - which, despite being shot in the same British seaside town and having the same lead actor, was utterly different in character. The producers and writers recognized that a complete reset was needed, and accomplished it successfully - quite analogous to the origin of
TWOK, seems to me, even though the latter didn't involve complete replacement of the supporting cast.
