The library is pretty great in some other respects, though. Whenever Bella finds herself at a loose end, she reads ahead and outlines essay assignments for the courses that are kind enough to offer syllabi so she'll be able to dash off and work on other things if the fancy takes her. She is strict about holding herself down to no more than one hour of outside-class flying a day, two on weekends, even when the weather is really nice (which it virtually always is). She got sufficiently nasty (and, for that matter, pleasant) surprises about features of the wizarding world in her first few days of immersion that she thinks it's probably a higher immediate priority to get a lot of reading in.
Then it's a Wednesday afternoon, Bella is between books, and she spots Feral at dinner.
"Hey, did you practice?" she asks him brightly.
And lo, after dinner, they retreat to his room; it's Wednesday and she's staying out of her room till curfew. She sits and produces her vine wand. (She's developing a fairly good intuitive sense of when she'll get better results with one or the other, though she doesn't consider herself to have mastered a spell till she can do it with both.) "Ready?" she asks, looking into his eyes.
"I don't think that's - I'm making this up, but I have a sort of idea that what it's supposed to be is more like not feeling things? Like, focusing really hard on nothingness and if you have feelings about stuff then it just paints big arrows at stuff I could look at."
"I don't think I will. I guess I might if I thought somebody was definitely going to try to do it for bad reasons or was going to modify my memory? Because then I'd want to really know if I could fight them off or not and better you reading me for two seconds and not wanting to learn anything too private than somebody else doing worse. But even then I probably would ask Sherlock instead because I don't want to catch fire and because he's pretty close to mindreading sometimes anyway."
"Hi, Sherlock! So apparently Feral makes a lousy Occlumency test subject because he has really intense feelings about most everything and can't calm them down and stop painting me big glowy arrows towards his thoughts, so I don't have a good way to figure out if anything I have him trying would work for me."
