Invisible-->Gradual Realization-->Visible only to himself, but not blind-->Invisible
The narrator's story seems like a cycle. In the beginning, he was naive and docile. He took his grandfather's words literally. He gradually realizes his naivety through the Brotherhood, and finds out that he is visible only to himself. However, he knows that he should not be blind (betrayal). At the end of the book, he comes back to being invisible again- this time, he is not naive, but knowledgeable.
