4x22 - Hercules: The Legendary Journeys

While Iolaus paid a visit to his mother, Hercules explored Olympus. He was hurt to learn the real reason his father had brought him there: Zeus needed protection from Hera and the other gods, who were conspiring against him. But Hercules couldn't turn his back on his father. Then Zeus allowed Hera to rip away his godhood in order to save Alcmene's spirit from eternal hell. Hercules went to the dark side of Olympus, where he overcame Apollo and Hera in battle. Zeus' godhood was restored, Alcmene returned to the Elysian Fields, and Hercules became a half-mortal again.
