Najwa now:
Angie I think you're on to something. Maybe its not traces of magic
that we need to be worried about him sensing, but think about it, he
has the ability to sense when Voldimort is near or just about anything
Voldimortish really. So if he's near a horcrux, I wonder if his scar
will hurt as well? Great like of thinking you've got us on...that
could help him find them a little easier.
