"Teach people the song-spells you've made up, in exchange for stuff. Information is a trade good! That's why it's not ripping you off to exchange your hair for the slippers, is because we're telling you all this stuff too."

"Oh! Okay, if people want them I can do that. And make up some more."

"Yeah! There are three academic tracks, basically. Artificing, Alchemy, and Incanting. Wilbur's doing artificing. I'm doing incantations; that one splits up again into two parts: creative writing, and languages. I'm languages. I don't write new spells, mostly; I learn ones that exist. I speak loads of languages so I can draw the spells I ask the school for from a wider pool."

"Oh. I know how to sing some other languages a little but I don't speak them particularly."

"--That's not great. The Scholomance will give you spells in any language it thinks you know, and it doesn't need much provocation to think you know a language, and if you don't learn a spell it'll start giving you worse spells or none at all. You'll want to bargain for help translating any spells you don't understand and work really hard in languages class."

"I mean I know how to look things up so I know what the song is about and I can pronounce it all! I just can't like have a conversation in Spanish."

"Trying to cast a spell without a really good idea what it does is a bad idea, and it's also a bad idea to take library books out of the library, and there isn't a great other source for language dictionaries besides the library. So you'll have to wait until you can go to the library to look things up. And there's curfew, and if you're out past curfew you'll die."

"...okay. So is there like, Spanish club. Or Latin club."

"...No. There are not really clubs. There are--alliances, of varying degrees of strength, culminating in the official alliances of senior year, but alliances aren't about shared interests, they're about shared survival."

"I can't be the only person who needs Spanish practice! There are so many kids here!"

"Kids with mundane parents usually don't get picked up by the Scholomance. There must have been some deaths before anyone could find out to re-allocate spots. Wizard parents make sure their kids know languages well enough or not at all before we go."

"Okay, well, who else is there, I can start a Spanish club."

"I don't know, I haven't approached anyone else so far. Let's go find some more muggleborns and we can discuss Spanish and maybe we can buy their hair." 

"Okay." Also it has begun to occur to Rebecca that she might now in real life be living out a weird sex fantasy where she's arm candy for a powerful chieftain of some kind in olden times and he will protect her from bears, except for bears read monsters, so. Eyes peeled for cute boys. If she lives she'll apologize to her parents and if she dies she'll apologize to God.

Eventually she decides that a cute boy will plausibly be more help than a Spanish club and gives Lucy her room number so she can leave her a note or something later if such a club materializes.
