Which they are. Sadde's suggestion that they try focusing on shorter parts of memories for a higher happiness-per-second value helps him but not Miranda, so he ends up with a more solid fog. Still just fog, though. They continue reading books about it, and it seems to just be that idiosyncratic. Interestingly enough, some books written by alchemists also have mentions of Dementors, trying to figure out what their symbolic value is and whether it's possible to integrate it. More advanced books are in the Restricted Section, and they won't have access to it until at least Professor Slughorn gives them the go ahead.
The year passes. Willow is consistently good at the theoretical parts of classes and consistently bad at the practical ones, mostly due to being flustered by failures and not quite being able to get over that fact. Sadde and Miranda are exceptional at Potions, and the only reason Sadde isn't also exceptional at Transfiguration is that he doesn't quite care enough about homework when all that's on the line are his grades. That, plus all the time he spends between reading about Dementors, reading about Alchemy, and trying to undo the damage suffered by Slytherins because of the Dark Lord.
That last goal has the most tangible results, for a certain value of "tangible." Slytherin firsties are divided between liking him (Jacob and two of the girls) and grudgingly tolerating him (the other boy and girl). He has thoroughly dispelled the notion that he's "just another Slytherin" firsties from other Houses (except perhaps Gryffindor) might have, but of course that doesn't make the older years all that happy. Well, not that the older Slytherins actually care that much. But he has helped various of them with various things, mostly by acting like a somewhat willful minion, since there's not much more he can do to help older students beyond that, so he's at least on talking terms with most of them (Cole and Astoria have been quite useful there, as well).
Arens is not one of them, but by now he's mostly just ignoring Sadde and hoping he'll just go away.
Summer arrives.
They return home and spend a while with their respective families, but eventually...
Willow sends everyone letters via owl, telling them she's got her house's fireplaces hooked up to the floo network, and that they could get there on that given day and is it a good day for everyone? They can bring their parents and siblings and whatever they want, the house can accommodate lots of people.
They are inside, so they can't see the entire expanse of the house, but if this one room is anything to go by, it is big. The fireplace is large enough for three people to stand in it without crowding each other, and there are two couches sorta-facing it at an angle with a centre table directly in front of the fireplace itself, and on top of what looks like a very expensive rug. The walls are white and the ceiling is tall and there is pretty decoration inlaid with gold, and another table over there with a few chairs, and book shelves, and one door on the wall to either side of them.
Willow giggles. "Okay, so, what do you want to do first? I can show you around and we can hang out in the library and we can have tea and we can swim in the pool and we can ride ponies and we can play golf and we can play tag, oooh we could also play hide-and-seek, my siblings never played with me, they were always too busy being prodigies, my older sister and the twins are here though so if you want to meet them you can, and mum is too although dad isn't."
"It's because it's actually really hard to do it right, if you swing too hard you overshoot the target, but not hard enough and you don't quite reach it, and the hole is only big enough for the ball to fit so you have to be really precise. ...it's not actually much fun as a team sport though I just suggested it because we have a mini-golf course."
"Nice to meet you, loves. Would you like me to make you something?"
She looks at the other three, but pretty meaningfully at Karen, and says, "It's okay, you can ask for whatever you like and there won't be any problems."
"They might not be assessing the risk quite right but it would have been pretty easy to ask Ms. Hannah for pumpkin juice, say, and she's probably already wondering why Karen is dressed like that." (Karen lacks Muggle street clothes; what she has on is not a school uniform, but it would barely be in-place at a renaissance faire, let alone out and about in a Muggle town.) "The risk is much worse for Ms. Hannah than for Karen, whyever her parents made the rule, anyway."
There are at least three rooms that could be reasonably called "living room," and there's the dining room there, and the games room, which has a chess table and a checkers table and a backgammon table and a go table and a few other scattered tables and chairs and a little couch and decks of cards.
"See anything you like here?"
First is the study it is relatively small, compared to the rest of the house. There are two desks filled with papers and one computer on each, as well as a bookshelf, a couple of chairs, a corner table, two armchairs, and Willow's mum on one of them, reading bunches of papers and writing stuff on them.
She looks up when Willow knocks and opens the door, and smiles at them, standing up to greet them. You can definitely see the family resemblance, there. "Hello! You must be Willow's friends. I'm Catherine."
There's even a corner with a few books about magic! Very few of those, though, bought very recently during visits to Diagon Alley. Willow's schoolbooks are there as well.
A large part of the books are secondhand. In fact, the only ones that aren't are those that look like secondhand versions would be rarer than new ones.
"No, definitely not, food's not allowed in here and she has little to do other than that. And when the cleaning lady comes there's this." She shows a little rolling door hidden in the upper side of the shelf that she can use to lock the books away. "We have lots of very valuable books here, hiding books is standard precautions."
Next next is Willow's room. It is very spacious and has a very large bed and a television and a PlayStation and a computer and lots of movies in VHS and DVD and figurines everywhere, mostly from SF&F stories. There are four differently coloured toy lightsabers hanging on her wall above her bed, and she points at those and reminds Karen of them.
And because she had planned for just such a conversation, she turns her TV on and there's already a Star Wars DVD there paused on a lightsaber duel scene.
Their duel has both the accompanying sounds from the TV and Willow's own personal sound effects. "Zwwwom! Chk! Bzzzzt!"
There are several movies. All of Disney's movies released so far, all of Star Wars, old movies like Gone With The Wind, a bit less old movies like The Godfather...
The inside of the house doesn't have much more to see. There are just the bathrooms, her parents' and siblings' rooms, several guest rooms, an attic with a bookshelf and an armchair and a lantern for some quiet alone time, and a basement where random stuff is kept.
Alright, maybe there was still a bit of stuff to see.
There's a backdoor that leads directly to the pool, and it's a massive pool, with a little waterfall and a fountain and a small island in the middle, a few tables with umbrellas and chairs, and two small locker rooms of sorts over there. From where they are, they can see the start of the mini-golf course from a distance, but not wherever it is the horses are kept.
The other reason for doing this is quickly and surreptitiously reaching the other two, bursting out of the water for an extra splash, then disappearing in the depths again.
Where might she be?
Well, whatever they want, really! ...within the limits of what the house actually has to offer. Since most sports involving feet are out of the question, there's: food ("I bet Ms. Hannah baked us muffins!"), board games, card games, hide-and-seek, lots of movies, and a bunch of PlayStation games.
