 A pretty girl, Salia, comes aboard the Enterprise with her diminutive guardian. She is to be taken to her home planet where she will fulfill her duty as the one to bring peace to the warring factions. Wesley falls for the girl and is no good to anyone as he woos her. Later we find she and her guardian are allomorphs, what in later sci-fi series are called shape shifters. Her guardian transforms into a monster that takes on Worf, and wins. Salia s natural form is something not as attractive to Wes, souring his ardor.
