hey 🙂 i see we're thinking along the same lines. but i do have to disagree with you on the cancelling out magic part. can't give you a proper reason as to why, but i just don't think that would happen. he couldn't touch harry before he used harry's blood to come back. but he always had very strong powers, he always knew magic and i don't think that would change by banishing harry's magic out of his system. also, i believe harry's not gonna loose or give up his magic. but i do like your theorie and definitly wouldn't mind hearing som others 🙂
