the Kirk-android's orders, it repeats the insult Kirk had used. Spock, realizing that this is not Kirk, forms a security team to follow the Kirk-android back down to Exo-III. When it reaches the planet, the Kirk-android encounters Andrea, who destroys him when he refuses to kiss her. The real Kirk convinces Ruk that Korby is a threat to his existence. Ruk begins to recall the clash between the "Old Ones" and the androids that led to his civilization's demise centuries ago. Korby enters, and Ruk confronts him, but Korby destroys Ruk with a phaser. Shortly afterward, in a struggle with Kirk, the skin of Korby's hand is torn, revealing that he is also an android. It is now revealed that Korby, dying of frostbite, had transferred his mind to an android body. He begs Chapel to believe that he is still the same man, but Chapel is repelled by what he has done to himself. Andrea, realizing she loves Korby, kisses him, and in despair, Korby fires Andrea's weapon between the embracing pair, destroying them both. Spock arrives with the security force, but finds that the crisis has passed. When Spock inquires about Dr. Korby's whereabouts, Kirk replies, "Dr. Korby was never here." Chapel decides to stay on with the Enterprise and finish out her tour of duty. Spock tells Kirk about his dismay of using the term "half-breed" to warn that something was wrong. The captain says he will remember this should he find himself in a "similar situation." Production The episode was written by Robert Bloch, but received rewrites during shooting by Gene Roddenberry.
