"Oh!" gasped Digory as if he had been hurt, and put his hand to his head. For he now knew that the most terrible choice lay before him.
"What has the Lion ever done for you that you should be his slave?" said the Witch. "What can he do to you once you are back in your own world? And what would your Mother think if she knew that you could have taken her pain away and given her back her life and saved your Father's heart from being broken, and that you wouldn't - that you'd rather run messages for a wild animal in a strange world that is no business of yours?"

Your Father need never know. No one in your world need know anything about this whole story. You needn't take the little girl back with you, you know."
That was where the Witch made her fatal mistake. Of course Digory knew that Polly could get away by her own ring as easily as he could get away by his. But apparently the Witch didn't know this. And the meanness of the suggestion that he should leave Polly behind suddenly made all the other things the Witch had been saying to him sound false and hollow. And even in the midst of all his misery, his head suddenly cleared, and he said (in a different and much louder' voice):
