It's not the first time that closeups and establishing shots differ - this sort of impromptu "angle change" crops up all over the place. Just two that spring to mind are McCoy & Kirk's initial conversation in Amok Time (McCoy's closeups do not match) and in Is There In Truth No Beauty where Spock and Miranda are carrying the Medusan to his cabin for the first time. The camerawork is lovely, but the marrying of the footage between Spock's closeups, Miranda's closeups and the medium shot of them both is way off. This is just one of those things I intend to "squint" at, because otherwise it is a continuity nightmare!!!
