“Well, I do think someone might have arranged our meals,” said Digory.
“I’m sure Aslan would have, if you’d asked him,” said Fledge.
“Wouldn’t he know without being asked?” said Polly.
“I’ve no doubt he would,” said the horse. … “But, I’ve a sort of idea he likes to be asked.”
Answer: The answer is He likes it, He may have pre-planned that we’d ask, and to change us.
