It is possible Anne came by her unicorn obsession honestly.
"They're really hard to find! But you can take Care of Magical Creatures later and there might be some you could meet."
"My books are kinda buried, but if either of you can get to yours I bet Fantastic Beasts has a unicorn section?" Emma suggests.
Miranda goes for her trunk and opens it up. It is neatly organized. She finds Fantastic Beasts and opens it up to the page on unicorns, which is illustrated with a moving photograph.
In deference to the new best thing ever picture, her hair has been lightened to a whiter shade of silver, and her horn is now a silvery blue. The sparkliness remains, however, because why not? Sparkles!
"Wizard photographs are pretty good," agrees Miranda. "Well, for this kind of thing. My mum thinks Muggle photographs are better for artistic shots because you can line things up just one way."
Nothing she's ever drawn has moved (and with four younger siblings, she has been the doom of a rather impressive number of crayons) but she does have a wand now...
"You can make paintings do it," says Miranda. "But it doesn't happen by itself, you have to make the painting special. The photographs have to be developed in a potion, too, to do it right."
"Uh, hey guys?" Emma breaks in nervously. "I think the train's about to leave, you should probably say goodbye to your parents?" She looks enviously at Jenny's glittering hair. "We could sit together on the train though. Um, if you want to."
"Oh, yeah, let's all get a compartment," agrees Miranda, and she walks back to her mum, and hugs her, and gets kissed on the forehead, and goes onto the train.
"I'm in!" Jenny agrees immediately. "My parents are at work, so I'll get us seats I guess? Nice to meet you all!" She fetches her stuff, calling an extra thank you back to Miranda's mother in the process. (Imagine if she'd run into Emma's parents first? Emma was nice, but her parents were... well, Jenny's now extra glad she met the Swans first.) And onto the train she goes to find a free compartment.
Her mother just sniffles and tells her to be good and study hard and make them proud. Her father tells her the same, but adds, "And remember, you'll be there for seven years! You have plenty of time to make friends! Lots of students there with good connections. Good opportunity, that."
"Don't worry, Father, I'll remember," Emma agrees neutrally, mentally translating to and try to find some friends we like better. Since historically, the overlap between children her parents consider Valuable Connections and people Emma can even begin to tolerate doesn't actually exist, she's not going to promise anything.
"That's my good girl," her father says fondly, and hugs her again. "You'll be a wonderful witch, just you wait and see."
Emma smiles weakly in response. Gathering her stuff, she follows the other two girls onto the train just as they're yelling the last call. She finds Jenny in a cabin near the back, conveniently close to where they all got on. "Oh, bliss, I can sit now, thank Merlin. Mother wanted to be extra, extra careful so we arrived hours ago."
Two hours is in fact hours, even if it is the minimum number of hours to qualify as plural. It is still much, much longer than Emma wanted to be standing.
"We ran late because Mum wanted to walk as it's a nice day, and it wasn't making us late enough that I could argue her into taking the Underground." Most of the compartments are occupied; they have to duck around the snack cart to get past lots of full ones. Eventually there is an empty one. Miranda ducks in to claim it.
"The Underground?" Emma asks curiously. "Oh, uh, that's that Muggle train, right?"
"Yes. Renée - that's my mum - doesn't like the Floo. She has a broom but I don't fit on it so even if she Disillusions us it doesn't mean we can fly around in the middle of London."
"I haven't taken the Floo much," Emma admits, "but I kinda see her point? It's, um, not the most comfortable thing in the world. Mother found us a Portkey to the station; that's kinda why we were so early."
"Okay, is there, like, a cheat sheet or something?" Jenny asks plaintively. "Magic to Muggle dictionaries? Wizarding Gobbledigook 101? Help, someone, take pity on the confused Muggle please!"
"Sorry," says Miranda. "The Floo is a way to go from one fireplace to another by magic, but it makes my mum dizzy and it's also very hard to land on your feet. A Portkey is a thing that is enchanted so if you touch it, it puts you somewhere else. Brooms fly. And there's this train, which is somewhat magical but mostly only a train, and in other countries there are are magic carpets but not so much here, and apart from, like, things like sitting on magical animals and special-purpose-built things that aren't any of them very common, that's most of the wizard methods of getting around."
She makes an exaggeratedly sad face, and switches her hair to a rather dismal shade of blue-grey just for emphasis. "See? So very sad."
And, after a second's thought- "...is there a female form of that? Metamorphmaga? I mean, um, it's kind of Latin. I've never heard it, though."
It's not particularly efficient- it's noticeably slower than even the unicorn horn- but her hair does start to move into a braid-like form.
"I think it's just Metamorphmagus for boys or girls. But if you want to say 'witch or wizard' without it taking all day you can say 'wix', and like - at least the sort of person Renée hangs around with will know what you mean." She supervises the braiding process with fascination.
Her hair has made it successfully into a braid. It's not elaborate, nothing she couldn't have done with her hands- not even a French braid- but it's definitely a braid now. She beams.
"I did it! Eeeeee! Gimme something else to try?"
