You have to remember that You Only Live Twice is the novel after OHMSS, Bond is still an emotional wreck, then he is sent to Japan.
That’s what threw the whole movie franchise off, because exclusive film fans don’t realize YOLT should be occurring AFTER OHMSS. I’m struggling to remember at the moment if they intended to film OHMSS immediately after TB (which should’ve said in the end credits, “JB will return in...”). They had to use the opener of DAF to make it look like JB was finally out to avenge his wife’s murder, when he buried alive the cosmetically-altered Blofeld double, with his line, “See you in hell...”
Confusing as well is that it seemed like JB wouldn’t have been “introduced” to Blofeld in YOLT since he would’ve already met him face to face in OHMSS (and the scene in YOLT would’ve been the first time he’d have met Blofeld in the film franchise). That’s the problem when they alter the novels to fit the films, of course.
