Odin's lost eye reveals more secret history to Thor. Odin is forced to give up Idunn to the Storm Giants, but thanks to Loki's trickery they're willing to give her back for the Rhinegold. Odin, Thor, and Loki confront Alberich, who has fashioned the Rhinegold into the Ring of Nibelung. They defeat him and win the horde, but not before Alberich curses the ring. Odin reluctantly turns over the ring to the Giants and Fafnir kills Fasolt so he won't have to share the prize.
