Quote 1
"Who said anything about safe? 'Course he isn't safe. But he's good. He's the King, I tell you." (8.26)
Mr. Beaver distinguishes between being fundamentally good and being gentle or "safe" to be around. Aslan is good, but he's also terrible, awesome, and powerful. In this book, good is not going to just lie down and turn the other cheek. Well, OK, it is, but it's going to be pretty awe-inspiring at the same time.
Quote 2
"The reason there's no use looking," said Mr. Beaver, "is that we know already where he's gone!" Everyone stared in amazement. "Don't you understand?" said Mr. Beaver. "He's gone to her, to the White Witch. He has betrayed us all." (8.53)
Mr. Beaver isn't prejudiced by a family relationship to Edmund, and he's able to recognize right away that Edmund's sudden disappearance means trouble and danger.
Quote 3
"I didn't like to mention it before (he being your brother and all) but the moment I set eyes on that brother of yours I said to myself 'Treacherous.' He had the look of one who has been with the Witch and eaten her food. You can always tell them if you've lived long in Narnia, something about their eyes." (8.61)
Like most people in Narnia, Edmund wears his heart on his sleeve. OK, well, nobody falls in love here, but you know what we mean – he wears his thoughts on his face. Appearances are rarely deceptive in this world, and if Peter, Susan, and Lucy had known what to look for, they might also have realized what was happening to Edmund.
Quote 4
"Aslan a man!" said Mr. Beaver sternly. "Certainly not. I tell you he is the King of the wood and the son of the great Emperor-Beyond-the-Sea. Don't you know who is the King of Beasts? Aslan is a lion – the Lion, the great Lion." (8.22)
Narnian mythology suggests that the great Lion Aslan has a strange and powerful father, the "Emperor-Beyond-the-Sea," who remains mysterious but sounds totally awesome.
Quote 5
"Down at Cair Paravel – that's the castle on the sea coast down at the mouth of this river which ought to be the capital of the whole country if all was as it should be – down at Cair Paravel there are four thrones and it's a saying in Narnia time out of mind that when two Sons of Adam and two Daughters of Eve sit in those four thrones, then it will be the end not only of the White Witch's reign but of her life. (8.41)
The arrival of Peter, Susan, Edmund, and Lucy in Narnia is not a mere accident or a convenient occurrence. Instead, it is the fulfillment of an ancient prophecy, with deep spiritual overtones for good Narnians like the Beavers.
Quote 6
But amidst all these rejoicings Aslan himself quietly slipped away. And when the Kings and Queens noticed that he wasn't there they said nothing about it. For Mr. Beaver had warned them, "He'll be coming and going" he had said. "One day you'll see him and another you won't. He doesn't like being tied down – and of course he has other countries to attend to. It's quite all right. He'll often drop in. Only you mustn't press him. He's wild, you know. Not like a tame lion." (17.23)
Aslan's ways are not the ways of men (or Narnian creatures), and there will always be something inexplicable and mysterious about him. He can't be tied down to a regular schedule and he won't ever do things in quite the way you expected.
Quote 7
"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.
Quote 8
"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.
