A viewscreen comes on and displays a pre-recorded message from Losira, a Kalandan who had been the last survivor at the outpost. She had programmed the computer to defend the outpost and it used her likeness for the assassins. The recorded Losira explains that while creating the planet they also created a deadly organism. McCoy surmises that the disease spread throughout the Kalandan race and drove them to extinction long ago. Kirk suggests that the landing party had survived only because the image of Losira was so complete that it experienced regret about killing.
