TUC followed up on the story elements from TWOK, TSFS, and TVH, but did not have Saavik. From MA:
So, what is your opinion? Would you have liked to see Saavik return and play the traitor? Or were you happy with the (somewhat obviously guilty because she was new) character of Valeris being the traitor?
Also, if you chose Saavik, who would you want to play the role?
Saavik was to have reprised her role in Star Trek VI: The Undiscovered Country, but was replaced with Valeris, reportedly because Gene Roddenberry was concerned that fans had become so fond of Saavik that they would react negatively to her turning out to be a traitor. Also, no one wanted to have to cast a third actress to play the same role.
