Okay, that was an unexpected result. I wonder if that wave of magic will encompass just Great Britain or the whole world? It should be rather interesting if Harry manages to survive with his magic intact (then again, the inversion on his magic should have some other interseting effects). It's going to be very interesting to see if Hermione, Susan, and the young'un inside Susan retain their magic after that golden mist has passed; I could see Harry's power making an exception for them (some of a passover effect) but either way will make for an interesting story.
