Where Have You Gone?
This is some speculation about what happened to some supporting
and guest characters after we stopped seeing them on their respective
Spock's child from their mating on the Genesis Planet, and then much
later married him (was originally the plan in ST:IV but not shown but
in TNG it's mentioned that Picard attended the wedding of Sarek's son).
Later went on to become a Captain and an Admiral according to some
novels. Thankfully the plans to have the treacherous Vulcan in ST:VI be
Saavik were dropped in favor of creating a new character, Lt. Valeris.

with Picard and crew. Opposed Shinzon's coup, and took several dozen
Warbird's under her command to a secret location once he launched his
attack on the Romulan Senate. Returned months later after Shinzon was
killed and the USS Titan's task force had left Romulan space (she had
spies observing the whole time), and allied with Commander Donatra to
bring down the government of Praetor Tal'Aura (yes, the same Senator
that planted the Thalaron Bomb in Nemesis) and Proconsul Tomalak (the
new heads of state were named in "Titan: Taking Wing") and established
herself as Praetor with Donatra as Proconsul.
