Theme
Sarek confronts Kirk about Spock's katra (living spirit), stating: "He asked you to bring him to us and you denied him. You will find a way." The theme is established: the needs of the one outweigh the needs of the many - the inverse of Spock's sacrifice in Star Trek II.
Worldbuilding

McCoy begins acting strangely, speaking with Spock's voice and mannerisms. David Marcus and Saavik investigate life readings on Genesis, discovering rapid evolution.

Resistance
Kirk debates whether to defy Starfleet orders. Sarek pleads with him to help. Kirk attempts to get official permission but is denied. Meanwhile, on Genesis, David and Saavik discover a resurrected young Spock rapidly aging. Klingon Commander Kruge observes Genesis as a potential weapon and plans to seize it.

ConfrontationFirst Threshold
Kirk makes the active choice to steal the Enterprise and go to Genesis, defying Starfleet orders. He tells his crew: "The word is no. I am therefore going anyway." This irreversible decision launches them into their mission to save Spock.
Mirror World
Kruge and the Klingons represent the thematic counterpoint - they see Genesis purely as a weapon of destruction, while Kirk's crew fights to preserve life. Kruge destroys the Grissom and kills its crew, establishing the mortal stakes of opposing philosophies.
Premise

Midpoint

Opposition
Kruge captures Saavik, David, and the now-adolescent Spock on the disintegrating Genesis surface. The planet's destruction accelerates. Kruge demands Kirk beam aboard or watch his crew die.
