^ Very interesting! This explains a lot. Thank you, Therin of Andor!
Vonda McIntyre hit several assumption problems when novelizing ST II, because at the time it wasn't a given there'd be a ST III, or that she'd be novelizing it.
In the ST II novelization, Jedda is a bald Deltan (as suggested by the script). Saavik is attracted to David Marcus and a relationship develops. IIRC, Spock had taped a will requesting burial in space. Impulsive half-Romulan Saavik reprograms the burial tube to head to Genesis, where she assumes it'll burn up on entering its atmosphere. The book was written before the end scene of the tube on Genesis was added to the movie.
This was all tweaked for the ST III novelization, IIRC. The tube unexpectedly soft-lands, and is discovered by Saavik and David on Grissom, which reports it to Starfleet. Sarek had no idea Spock had baulked at his katra going into the Hall of Ancient Thought, but seemingly Spock had changed his mind by transferring it to McCoy. Amanda is studying to become a priestess and is not to attend the ceremony (or what ended up being the ancient Fal-Tor-Pan ceremony, a Refusion of a katra with its unexpectedly living body). We don't see her onscreen till ST IV. The Saavik/David romance as written in the books was complicated because
this film required the Saavik/Spock pon farr scene. Also, Saavik is treated
onscreen as a full Vulcan now, not the feisty half-Romulan of the ST II script and McIntyre's novelizations.
In the ST IV novelization, a male Deltan encountered by Carol Marcus has long hair (connecting back to explain the appearance of the actor John Vargas in ST II, who of course had no need to shave his head to play a generic Genesis scientist). This also caused confusions about Efrosians (ST IV and VI)
I elaborate on the Deltan/Efrosian dilemmas here:
