After giving the apple to Aslan, Digory feels more content, peaceful. C. S. Lewis wrote the Chronicles of Narnia to be Christian fiction therefore this scene symbolizes giving up temptation(s) to God. Digory was tempted to take the apple to heal his mother, to eat the apple, to take part of the apple to his mother. He was relieved of all this temptation when he gave it to Aslan, who let him take one from the new tree that sprouted from the one Digory had brought back to heal his mother.
they are different! icing is thicker, like the thing you use on cakes, and it is more fluffy. glaze is thin and it is something you would put on donuts!! glaze hardens over time but frosting doesn't!
