In "Cruel Tribute,” which character’s actions most advance the development of the plot?

Theseus’s decision to join the Athenian youths sent to Crete and confront the Minotaur sets the central action in motion. His choices inside the Labyrinth lead to the conflict’s resolution, so Theseus’s actions most advance the plot. Ariadne helps him, but she is not the character driving the main events.
