We're trying to figure out how this is happening, but as of now we do not have a clue. When we do, we'll be able to stop it - or possibly even control it. Who knows?
I don't think there is much of a chance, darling, but I do like to be on the safe side just in case. And if you want to go to the south of France I would certainly not blame you. I'll arrange your trip for you if you'd like. I need to stay here though, this is no time to ask for a vacation, I'd be fired on the spot and how would that look.
I'll make sure to gloat properly when I'm back home.
I can't assign Aurors to do anything, they're not my department. I can assure you she will only work with experienced Aurors, though I think she's perfectly safe at Hogwarts, I doubt very much Voldemort will return there.
Stephen should be perfectly safe as long as he doesn't come out of his lab, and knowing him there isn't much chance he will for anything save family dinners.
