Quote #4
Down below them, spread out like a map, lay the flat hill-top which they had struggled over yesterday afternoon; seen from the castle, it could not be mistaken for anything but the ruins of a gigantic city. (8.118)
The children and Puddleglum don't recognize the forest for the trees, so to speak, when they are struggling over the ruins of the giant's city through the storm on the previous day. The bigger problem here is that they've botched yet another of Aslan's signs and will have an even harder time completing their mission.
Quote #5
"Narnia? What land is that? I have never heard the name. It must be a thousand leagues from those parts of the Overworld that I know. But it was a strange fantasy that brought you seeking this—how do you call him?—Billian? Trillian? in my Lady's realm." (10.153)
This is a double transformation: Rilian has been enchanted and believes that he is the Black Knight (and that the Lady is a good Queen), and he is twisting the idea of Narnia and the lost prince to fit into his understanding of the situation. The Queen of Underland will take this re-shaping of the universe to a whole new level when she arrives on the scene.
Quote #6
"Every night there comes an hour when my mind is most horribly changed, and, after my mind, my body. For first I become furious and wild and would rush upon my dearest friends to kill them, if I were not bound. And soon after that, I turn into the likeness of a great serpent, hungry, fierce, and deadly." (11.156)
Rilian explains the need for the silver chair to the children and Puddleglum, but we're about to see that his understanding of the situation has been highly manipulated by the wicked queen. The transformation into a snake, of course, is reserved for the queen, but there is a change of mind during Rilian's fits: He actually becomes dis-enchanted and knows himself properly.
