In the beginning Theseus was determined to get to the Athens.
Theseus began defeating many demigods winning the heart of ladies and leaving them behind. He had beat the the minotaur with a sword and got out of the maze with a string. Theseus forgot to change the black sails to white sails.
In the end Theseus got back to the Athens and Aegeus thought that he had died so he threw himself off a cliff.
