Well we aren't all perfect especially dealing with an egotistical ass such as Draco Malfoy. It occurs to me how this event as bad as it is could be used as a way to actually put the fear of a grizzly painful death to the other death eaters and even Voldemort himself. I think Tom's biggest fear can be used to it fullest as I know when he learns how the Lestrange's died he'll be looking behind his back even in a supposed safe house.
Can I guess that a Certain American Federation family with the name of Stephens might be behind Harry's technomage skills and powers?

P.S.- Bewitching ain't it!
