I just rewatched the movie again today. A few points.
- Spock's character arc with respect to his battle between logic and emotion is depicted in the film as lasting his whole life, at least from the time when he is a little boy being bullied at school to after the time when Vulcan is destroyed. When Spock is a little boy, after the bullies taunt him into displaying emotion, Sarek lies to him about why he married Amanda, claiming it was the logical thing to do. This is in the context of a lecture about why Spock should control his emotions, lest his emotions control him. Then, we cut immediately to a meeting between young adult Spock and his mother right before he goes to the Vulcan Science Academy to decide his future. Spock expresses concern that Amanda will approve of his decision should he proceed with Kolinahr and purge all emotions. Finally, after Amanda's death, Sarek confesses to Spock the true reason he married Amanda, which is that he loved her. It is at this point that Spock has his epiphany, and stops being a Herbert. In fact, at that point the whole bridge crew reaches, and becomes one.
