Interesting escape and original with the magic suppression part. I guess he's fairly safe with Hermione with him. But it doesn't seem like Harry has many people he can trust. First Neville gives away the training plans, and now Bill is letting on about the will reading. Will Dumbledore be able to block that and keep Harry from inheriting? It is certainly looking unlikely that Harry will be emancipated even if he does become head of House of Black!
