Chihiro: "Haku, listen. I just remembered something from a long time ago, I think it may help you. Once, when I was little, I dropped my shoe into a river. When I tried to get it back I fell in. I thought I'd drown but the water carried me to shore. It finally came back to me. The river's name was the Kahaku river. I think that was you, and your real name is Kahaku river."
Haku: "You did it, Chihiro! I remember! I was the spirit of the Kahaku river."
Chihiro: "A river spirit?"
Haku: "My name is the Kahaku river."
Chihiro: "They filled in that river, it's all apartments now."
Haku: "That must be why I can't find my way home, Chihiro, I remember you falling into the river, and I remember your little pink shoe."
Chihiro: "So, you're the one who carried me back to shallow water, you saved me... I knew you were good!"
