"I do believe!" said Susan. "But how queer. They're nibbling away at the cords!"
"That's what I thought," said Lucy. "I think they're friendly mice. Poor little things – they don't realise he's dead. They think it'll do some good untying him." (15.12-13)
This may seem like a small incident, but Aslan won't soon forget the compassion of the little mice in the field. Even though he is magnificent and important, Aslan values the smallest creatures in his kingdom.

"Oh, Aslan!" whispered Susan in the Lion's ear, "can't we – I mean, you won't, will you? Can't we do something about the Deep Magic? Isn't there something you can work against it?"
"Work against the Emperor's magic?" said Aslan turning to her with something like a frown on his face. And nobody ever made that suggestion to him again. (13.48-49)
Susan still doesn't get it – the real point is not just to win and free Edmund and go home, but to do what's right. Aslan will do anything possible to help Edmund, except for undermining the spiritual foundation of the world. That would be too much to ask. Sorry, Susan.
Quote 3
The children were walking on hour after hour into what seemed a delicious dream. Long ago they had left the coats behind them. And by now they had even stopped saying to one another, "Look! There's a kingfisher!" or "I say, bluebells!" or "What was that lovely smell?" or "Just listen to that thrush!" They walked on in silence drinking it all in, passing through patches of warm sunlight into cool, green thickets and out again into wide mossy glades where tall elms raised the leafy roof far overhead, and then into dense masses of flowering currant and among hawthorn bushes where the sweet smell was almost overpowering. (12.1)
Peter, Susan, and Lucy have an innate appreciation for the beauties of nature.
