While Kes pursues a romantic interest,
the Doctor attempts to improve his program by including elements of the personalities of famous people he admires; as taken from holocharacters of them. As it turns out, the darker, less well-known sides of these people's personalities form a second, evil personality within the doctor. This evil version of the Doctor takes over and attempts to murder an alien from the planet which
Voyager is currently visiting, by pushing the alien off a cliff. The evil twin also temporarily paralyzes
Lt. Torres when she discovers his existence. At the episode's climax, the evil version of the doctor jumps off a cliff with
Kes but they get beamed back to
Voyager while falling. Upon returning to the ship, the Doctor's program is restored to normal. Summarily, just before the end credits, the Doctor is heard reciting part of the
Hippocratic Oath (the medical professional's pledge) which begins with the solemn promise to "do no harm." ==Reception==
