A small chuckle escaped Ollivander's lips. "Well yes, I suppose that would have been quite morbid." quickly he put away the wand, leaving only one box unopened. "Now we get back to my original point, why are Half-bloods so fascinating? You see I have a theory, one that other wand makers share but it is widely considered to be nonsense by anyone outside of the field. You see if that one parent is a pure-blood, meaning they have a history of wands which work for that family, and one parent is new to the magical world, meaning their magic is new and not refined by generations of magical influence, this can in some cases introduce an element of chaos into the child's magic. This could mean new wonderful magical abilities or could be old forgotten aspects of a family's magic to return. Which means your wand could be anything. We might be here for a while, Mister Potter."
