Yeah, he did. She was in charge of the labyrinth I think, or maybe the sacrifices, I can't remember. Let's just say she did it because she didn't like people dying.

[Better, right?]

So she told Theseus the way to the center of the labyrinth and gave him a ball of string to unravel behind him so he wouldn't get turned around. He went into the maze with the sacrifices and led the way to the Minotaur, who didn't stand a chance because Theseus was so strong. He killed it like he promised, then escaped with the other Athenians and Ariadne and sailed home. But Theseus was an asshole, because the Greeks really have a thing for assholes, so he ditched Ariadne on an island on the way back and then forgot to put the white sails up. When his father saw the black ones, he threw himself into the ocean out of grief and died.

[A happy story!]
