I haven't seen this particular picture or its accompanying discussion anywhere on my flist, and I would have thought it would have polarized folk! Had to wait until I turned the pages of a magazine, what's up with that?
Me, I'm thrilled. I always thought Harry's suspicions about that should have been answered, one way or the other. And I feel the choice to show Draco displaying the mark eliminates any possibility that it's an afterthought.
