“If you’re thirsty, you may drink.”
They were the first words [Jill] had heard since Scrubb had spoken to her on the edge of the cliff. For a second she stared here and there, wondering who had spoken. Then the voice said again, “If you are thirsty, come and drink,” and of course she remembered what Scrubb had said about animals talking in that other world, and realized that it was the lion speaking. Anyway, she had seen its lips move this time, and the voice was not like a man’s. It was deeper, wilder, and stronger; a sort of heavy, golden voice. It did not make her any less frightened than she had been before, but it made her frightened in rather a different way.
“Are you not thirsty?” said the Lion.
“I’m dying of thirst,” said Jill.
“Then drink,” said the Lion.
