5x8 - Hercules: The Legendary Journeys

Hercules and Morrigan were enjoying life on the island of Eire until they found the Druids slaughtered. Recognizing the work of the demon Dahak, Hercules and Morrigan returned to Sumeria. There, they found Nebula had been bothered by waking dreams of her dead love, Iolaus. When Hercules visited Iolaus' tomb, he found it empty -- and turned to find Dahak behind him, in the body of Ioalus. As they fought, hercules could not bring himself to slay his friend, even though he knew it was no longer Iolaus. Dahak escaped, with Hercules, Morrigan and Nebula in hot pursuit.
