"We've already seen what they can do," Theodore pointed out, chewing his lip. "It would be more...catching them do it. The worst part is...it would be easy to blame the Death Eaters but...well, purebloods losing their magic isn't exactly on their agenda. Especially not when..." He faltered a little.

The two of them certainly weren't going to figure it out.
