Zeniba: "I'm sorry my sister turned you parents into pigs, but there's nothing I can do. Its just the way things are. You'll have to help your parents and Haku by yourself. Use what you remember about them."
Chihiro: "What? Can't you please give me more help than that? It feels like I met Haku, but it was a long time ago..."
Zeniba: "That's a good start! Once you've met someone you never really forget them. It just takes a while for your memories to return."
