Took but did not read; wasn't sure what to do with, wanted to read, correctly anticipated that keeping would eventually lead to reading, finally boxed and tied and hid them so no one else would read them, either. This is also something it would be polite to mention, but she isn't sure how to bring that up without it being awkward. (Which is sort of a funny concern, with Rodolphus Lestrange, but Ilde has a higher threshold than some and a tendency to blitheness, so there's that.)

So she doesn't. Maybe it'll come up later, more naturally, or maybe it won't, or maybe Rodolphus will find them himself and realize, or- well, she tilts her hat so she can see him properly and says, “Then we should find you new books,” as though it's the natural continuation of her keeping his old ones.
