It's so ironic that the clues have been there all along. It's just that nobody either has thought to put them together, or come to the correct conclusion. I do think that if Dumbledore knew what my real long-range plans are, I'd be Obliviated and out of Hogwarts so fast that the speed of light would look rather slow and crippled. However, luckily for me, he never has Legilimensed me, and sees me as an adjunct to my two friends. He pays a lot more attention to Harry Potter than he does to me, and that's just the way I like it.
