Man vs polar bear - His Dark Materials

Is she? Settle thy way, child. You have to stop. There are innocent people here. They have taken one of my bears. What do you want? I want to fight you. In single combat. If I win, you leave these people alone. If I lose, you do whatever you want with them and me. You wish to fight me? It would be shameful to fight you. You are as weak as an oyster out of its shell. Let's make it a fair fight then. You have all that armor. I have none. Give me a piece. Anything you want. We'll be better matched then, won't we? Do you know what you are doing, boy? Sky Iron, am I right? Impenetrable, I heard. That's surprising. I guess I have to fight you without armor after all. I cannot fight that. That knife is too strange. You win, boy. Free that bear now. You heard the boy? Do it!
