Quote #10

Something Zachariah told me filled my mind and excited my heart: "A sailor," he said, "Chooses the wind that takes the ship from safe port... but winds have a mind of their own." (22.206)

The novel ends with Zachariah's words getting written down by Charlotte. That is, she quotes him and uses that quote as the novel's last words. Why is this significant? How do you think Zachariah and Charlotte need each other?
