Perseus is talking to the gray woman and then he takes her eye. Then he refuses to give it back until she tells him where to find the nymphs of the north. He gave back the old woman her eye and found the nymphs and received their gifts.
Perseus just landed on the island with Medusa with the help of his winged sandals. He weld his sword and struck off her head with one swift swipe. He stuffed the head into his magic wallet.
After Perseus slayed Medusa, the other two gorgons heard her body thrashing around, they flew into the air in pursuit of Perseus but ultimately could not find him because he had on this cap of invisibility and flew off faster than wind in his winged sandals.
Now Perseus headed home for Hermes. On his journey he encountered a dangerous who hindered his journey but he ultimately slayed the sea creature. This creature was bout to devour a beautiful princess Andromeda.
Perseus sailed away to another island to watch the games that were happening. He sailed away with his mother, Danae, and his wife, Andomeda.
Upon arrival, Perseus picks up a discus and threw it. As it left his hand a wind picked it up and blew it into the grandstand. Which ultimately hit King Acrisius and killed him, which fulfilled the oracle at Delphi, which predicted that the king would be killed by his grandson.
