If someone else has already posted about this, I do apologize, but let’s set the way back machine to the very beginning of our journey with Harry. In “Storm Front” just after we first meet Murphy, Harry says “My shadow and Murphy’s fell on the floor, and almost looked as though they were sprawled there. There was something about it that bothered me, a nagging little instinct that I blew off as a case of nerves.”  Given that we now know Anduriel is a Master of Shadows/Spy Master, could that have been Anduriel watching Harry way back then?
