This year also sees the two of them invited to something called the "Slug Club".
As for the "Slug Club"—what.
Karen and Willow don't have invites.
Willow is not bummed out by this. At all. Nope. She is very glad her friends get to go and be special and have fun with all the other special kids. Really.
"My mum used to go to the Slug Club when she was in school and she says it's not that interesting, literally just dinner with different food."
Willow is not sulking. She really isn't! She's just really busy with whatever-it-is she's doing right now. Very focused. Yes.
"I'm gonna guess Slughorn thinks he can predict who's going to be important for some value of important after school and he wants to ingratiate us? I'm not sure why he thinks he can predict that."
"Surely he knows you two are going to take over the world, it's gotta be obvious by now."
"I'm... pretty sure Miranda and I are not the first twelve-year-olds to say they're going to take over the world."
"It's more likely the interest in alchemy that caught his attention."
"And here I was thinking it was my looks and your charming personality."
She doesn't need help doing it she'll get in all on her own and no one can stop her they'll see, they'll all see!
Okay now what exactly are they supposed to do with the oysters and other materials?
Miranda starts writing.
So, they're supposed to turn an oyster into a pearl. There are several possible layers of metaphor he can work with here: creature to non-creature, rough to polished, manufacturer to manufactured... hmm.
No, that's too broad. Something more specific to the matter at hand. Pearls—he has read up on those—are generated when a minuscule irritant finds itself trapped within the oyster's folds. They create a "pearl sac" around the irritant and start depositing certain chemical compounds inside it in an immune response.
From that stuff like irritation, threat, immunity, trap, chemical compounds...
What materials does he have to work with?
