In Star Trek II: The Wrath of Khan, Spock tragically sacrifices himself to save the Enterprise. During his funeral, his body is jettisoned from the ship onto the planet Genesis.
In the following film, Star Trek III: The Search for Spock, Sarek criticizes Kirk for not bringing his body to Vulcan instead.
Sarek: Why did you leave him on Genesis! Spock trusted you. You denied him his future!
Kirk: I saw no future.
Sarek: Only his body was in death, Kirk. And you were the last one to be with him.
Kirk: Yes, I was.
Sarek: Then you must know that you should have come with him to Vulcan.
After Kirk asks questions about what he means, Sarek clarifies.
Sarek: I had assumed he mind-melded with you. It is the Vulcan way ...when the body's end is near.
However, Lt. Saavik, another Vulcan, was aboard the Enterprise when all this happened. Why didn't she ask these same questions about whom Spock might have mind-melded with? Why didn't she investigate more into this and advocate for bringing Spock's body to Vulcan, rather than jettisoning it to the planet?
