When Sarek visited Kirk and asked him to bring Spock's katra to Mount Selaya, why was it neccesary for Kirk and his crew to steal the Enterprise in order to do it? At the time that they were stealing the ship, Kirk & co. had no idea that Spock had been rejuvenated on the Genesis planet. As far as Kirk was concerned, Spock's body burned up in Genesis' atmosphere, so there was nothing to recover on Genesis. Spock's katra, at the time, resided within Dr. McCoy. If Sarek wanted the katra returned to the Hall of Thought (from the books) at Selaya, then all Kirk needed to do was bring McCoy to Vulcan and perform the ceremony. It wouldn't have beeen illegal for Kirk and McCoy to do so. Did I miss some dialogue? Why were they going to Genesis?
