In Warrior... Princess, Diana's father asks Xena for help with his daughter's marriage etc.
Xena takes over the role of Diana, and Diana takes Xena's role, and also runs into Gabrielle, whom she finally convinces, that she's Diana, not Xena. In Warrior... Princess... Tramp, Diana's royal position, as well as family are threatened by a 'tramp'--another lookalike, named Meg, (also played by Lucy Lawless), and of course Xena comes to the rescue but there are some big mix-ups.........
