During Spock's funeral, Saavik has quite a bit more to do. There are a few added lines here and there in the script that Spock is setting her up to be the Enterprises' First Officer. This is the first time Kirk addresses her with that same mindset.
So with the movie over and some of the changes annoted, there are a some things there that absolutely should hae been removed (the dumb bastard joke and some on-the-nose moments), but some things I'd like to have seen kept (Saavik being given a more "young leader in training" role).
Saavik in the movie comes across as just a new character, and in the script she seems to be set up as a replacement for Spock in future sequels. I also like that there is the BEGINNING of a David/Saavik relationship, and that it's not capped off at the end. Again, the feeling of setting something up for future movies.
This is the only draft of Wrath of Khan I was ever able to find, which is the Nick Meyer shooting script so sadly I can't do a comparison like I did with ST:TMP. If you have any of the early drafts, I'd love a copy/loan of them so I could do that comparison. Wrath of Khan also has an interesting (if much less volatile) history to its scripts. :)
Annnd Saavik ruins the moment by referencing a line from earlier during Kirk and David's fight to the death. For a joke.
