Warrior...Princess

S1 E15: Because of her startling resemblance to King Lias’ daughter Diana, Xena is asked to pose as the princess to help flush out a band of would-be assassins. When Xena responds to a summons for help from King Lias, she is attacked moments after entering the castle by the vicious Timus, whom she overpowers. The King orders his men to go after the deadly intruder and explains to Xena that the attempt on her life was meant for his daughter, Diana, who someone is trying to kill before her impending wedding to Mineus of Liberium. When Diana enters the room, Xena is stunned to see that she looks so much like the princess; they could pass for identical twins. Lias pleads with Xena to masquerade as his daughter in order to flush out the would-be assassins and she agrees to help. The real Diana, now disguised as Xena, leaves the palace in search of Gabrielle.
