5x11 - Hercules: The Legendary Journeys

Dahak, chained to the altar in the body of Ioalus, hatched a plan to kill Ares, which would give him the power to break his bonds. Meanwhile, the demon showed Hercules how he had seduced Iolaus at the moment of death. Apppearing as Hercules, Dahak promised Iolaus the power to set everything right in the world. With time running out, Hercules was sucked into the spiritual world, where he found the real Iolaus. The two friends fought side-by-side once more, sending Dahak into a fiery chasm. Then they siad good-bye, and Iolaus disappeared into a shaft of light.
