"Nope, chocolate's just awesome! Solves all problems. Even Dementors."
"Eating chocolate treats Dementor exposure. It doesn't hurt Dementors or work fast enough to let you hang out around them without being affected and it definitely doesn't prevent them from kissing you even if you fill your entire mouth with ultra-dark, the kind with cacao nibs."
"Ugh. I know it is not, like, an actual kiss but it is still so squicky to think about!"
"I knooooow. But it's one of the problems! Just... probably the least important one! Still, though. Creepy skeleton guys. Ugh."
When the train arrives, Miranda says, "We could see now if anything happens if you come in to our common room to have a look at the books."
The knocker says when they approach,
"I am part of a bird that is not in the sky. I can swim in the ocean and yet remain dry. What am I?"
Miranda puzzles over this, and says, "Karen?"
The door swings open.
"Oooh. Nice." Emma follows her friends inside, necklace in her pocket, ready to be put on when books are found. (She will be wearing it as little as possible, until then.)
The natives of this common room lead their visitors to this last and start looking for promising foreign language books.
"It works on reading," she reports. "Also, Miranda-" she picks one of the books and hands it to her- "this one had a couple chapters on Dementors in the index."
"Yeah, of course. I mean, don't lose it, Mother would be upset, but- I'm more likely to lose it than you are, really."
"Thanks! It seems like I should be more careful with it now. Cause... translation."
"Nooooo, don't do that," Alli says instantly. "They'll make you send it back."
"But it was Mother's family," Emma objects uncertainly. "She should know, shouldn't she?"
"Almost everything's in English," Jenny suggests. "You could tell them later, it wouldn't be weird, right? That you didn't notice earlier?"
"Well, does it work on spell incantations that aren't really Latin but are a little bit? Like, I don't know, aguamenti? Because if it does then it would be really weird not to notice."
Alli cackles. "Nuh uh! She'd have to be wearing the necklace for that. And unless we're translating something she wouldn't be doing that. Ever ever ever."
