A criminally underrated line of foreshadowing in The Lion, the Witch, and the Wardrobe is this:
“The coats were rather too big for them so that they came down to their heels and looked more like royal robes than coats when they had put them on.”
I just love that image. Right at the start, Lewis tells us that these four children look like kings and queens, and I think too often we just skip over it.
