"He has tried to betray them and joined the White Witch, O Aslan," said Mr. Beaver. And then something made Peter say:
"That was partly my fault, Aslan. I was angry with him and I think that helped him to go wrong."
And Aslan said nothing either to excuse Peter or to blame him but merely stood looking at him with his great golden eyes. And it seemed to all of them that there was nothing to be said. (12.18-20)
Peter immediately, without any prompting, takes responsibility for his part in Edmund's alienation and betrayal. Perhaps because Peter is so willing to recognize his own faults, Aslan sees no need to punish him.

"The potatoes are on boiling and the kettle's singing and I daresay, Mr. Beaver, you'll get us some fish."
"That I will," said Mr. Beaver. (7.46-47)
Mr. and Mrs. Beaver are the ideal Narnian couple. While Mrs. Beaver attends to the sewing and cooking, Mr. Beaver provides the food and keeps the house repaired. They're very much out of the time when C.S. Lewis was writing – the late 1940s, post-World War II.
