Susan asks about Aslan:
“Is he quite safe? I shall feel quite nervous about meeting a lion.”
“That you will deary, and make no mistake,” said Mrs. Beaver. “If there’s anyone who can appear before Aslan without their knees knocking, they’re either braver than most or else just silly.”
“Then, he isn’t safe?” said Lucy.
“He’s not safe, but he’s good.”
