Interesting update; I know I find it difficult to believe that the scar-horcrux should have been that big a deal and that it likely was so in canon only because Dumbles couldn't (or wouldn't) consult others. (Of course in canon, if Dumbles or Voldemort didn't know it, it wasn't worth knowing, as they represented not just the height of magical knowledge in Britain, but in the world)
