Yeah, Theseus wasn't very cool with it, so he offered to go to Crete to kill the monster. His dad really didn't want him to go, because Theseus was his only son, but Theseus begged him until he agreed, but he made Theseus promise to use white sails on his ship on the way back if he was safe. If the crew came back and Theseus was dead, they'd use black ones. So, Theseus went to Crete, but he had no idea how to get through the labyrinth. Minos' daughter showed up one night and told him she could help him kill the Minotaur, but if she did, he'd have to marry her.
