4x18 - Hercules: The Legendary Journeys

Autolycus convinced his former girlfriend, Cupcake, that he wanted to fix her up with Prince Alexandros at a royal ball. In truth, Autolycus wanted to steal the sapphire of Antioch from the prince. Introduced to Alexandros as Hermia, princess of Carpathia, Cupcake inadvertently delayed a war from breaking out between Carpathia and Antioch. But the traitor, prime minister of Antioch, stabbed Prince Alexandros. Finally King Georgas of Carpathia arrived and established peace, while the wounded Prince proposed marriage to Cupcake -- even though he knew her true identity. Too late Autolycus realized he was still in love with her.
