In the book Prince Caspian Reepicheep is a very brave, albeit proud mouse who loses his tail in battle. He is horrified and begs Aslan, the Great Lion, to give him his tail back. Aslan is not so sure, it seems that Reepicheep is a bit too fond of his tail for Aslan's liking. However, when the rest of Reepicheep's troop declare that if their leader cannot have a tail, they will forsake theirs as well, Aslan grants Reepicheep's wish saying:
"Ah, you have conqured me. You have great hearts. Not for the sake of your dignity, Reepicheep, but for the love that is between you and your people..."
I am thinking that perhaps the Great Lion sometimes disguises himself as a Japanese Elementary School Teacher.
