Ahsoka Tano: Master Yoda has a saying. “Old sins cast long shadows.” Do you know what he means by that?

Anakin Skywalker: He means your past can ruin your future if you allow it. But you forget it was Master Skywalker who said, “I don’t want to talk about my past.”

Ahsoka Tano: Okay, fine. There is so much more we can talk about out here. Like the sand.
