What Are Little Girls Made Of?

In Robert Bloch's original script, a wealthy socialite named Margo hired the Enterprise to look for Doctor Korby, whom she greatly admired. In his script re-writes, Gene Roddenberry felt the role would be better filled by Korby's wife or fiancée, which would play well with the doctor's alleged intimate relationship with Andrea and his emotional coldness. Finally, he wrote the part to feature Christine Chapel, who was previously featured in The Naked Time (1966) (and was played by Roddenberry's lover, Majel Barrett). In any case, money is no longer widely used, certainly not by the Federation, so it is hard to see how someone could hire the Enterprise.

One close-up of Kirk during his last conversation with Ruk is flipped. Notice that his hair is parted the opposite way and the colors of the costume are reversed.
