"I don't - especially want to talk to reporters," says Miranda. "But I can make the giant person Patronus even when I'm just in our dormitory, it wasn't a one-off, so I still want to kill more of them. I'd go with somebody if somebody will take me."
McGonagall stares at Miranda over her glasses. "You are in school, Miss Swan," she sighs, "though I suppose I cannot control your holidays. But while you are at Hogwarts, you are expected to attend your classes and complete your work." She taps her wand on the desk in thought. "Please tell a professor if a reporter attempts to contact you. Even if it's just an owl. That goes for all of you," she adds, looking rather sad. "You never know, these days."
"...um. Headmistress? Does this mean I can tell my parents now?" Emma ventures to ask.
McGonagall nods slowly. "We'll have to tell the Ministry, of course," she says, partly to herself. "Others will need to know about this. You do not need to maintain perfect silence, though, again- reporters should be sent to your teachers. Or really, anyone you do not know. But your parents, yes, your parents are fine."
"There's not like - an endangered species law or anything that someone can be stupid about if they decide they don't like me, is there?"
"Well, I don't think Alli would tell reporters," Miranda says. "Everybody else can just wait."
Given permission to tell her parents, there's nothing else Emma feels like asking the Headmistress. Hogwarts seems to have things under control; and anyway, it's not like she has any desire to talk to reporters regardless. She mumbles a thank you to the Headmistress and summarily flees the office. She knows she's not in trouble, per se, but in the office, it still feels like it.
Miranda lingers to inquire if McGonagall would perhaps like to see her Patronus and maybe cast spells at it to see why it's special.
Once Emma and Karen have left, the Headmistress sizes up Miranda. "Miss Swan. I believe a more thorough examination of your Patronus should be left to an expert; the Ministry has promised an experienced Auror 'at their first availability.'" She's a bit skeptical of this, as it happens, but it can wait. If the Ministry drags their heels, she'll worry about it then. "However, there remains the concern of your... less than standard wand. Professor Flitwick tells me you have seen unexpected results with it before?"
"It's mine," says Miranda. "I'll show you whatever you want to see but it's my wand, not a 'concern'."
"Given recent events, I should like to verify that it is not dangerous," McGonagall says mildly, if sternly. "You have proven yourself capable of feats with that wand that should be well beyond a first year. If the wand is in some way unstable, or powered by Dark Magic... these things are best discovered early." She softens slightly. "If it proves to simply be an unusual wand, that is a very different matter, of course."
"If you are even considering that you might take my wand away I would like my mum to be involved in the conversation." Since listening to Miranda herself is probably out of the question. "Casting a Patronus at all is supposed to be too advanced for a first year and I can do it with my normal wand too, it just gets me a smaller one."
McGonagall adjusts her glasses with a sigh. "If we disagree you are welcome to involve your mother. But as you have said, it's your wand, Miss Swan. You will need to be present and involved at least sometimes. I will not be... be..." she is somewhat at a loss for words here, "absconding with your wand to perform Nameless Tests without your input."
"Okay. Well, what Professor Flitwick saw was a feather going up really fast and sticking into the ceiling when I tried the Levitation Charm on it. When I try other things it does what I'm trying to do, just really - thoroughly. My Patronus in particular is about three times as tall when I cast it with the chimaera wand - the pawnshop person said it had chimaera hair in - than how tall it is when I cast with my other one."
