Ilde's fleeting glance before she answers is genuinely slightly amused - that's some cute underestimating you're doing there, human. She assumes, generously, that Narcissa doesn't intend to condescend to her and it's only a personal flaw. (The alternative is a prejudice, and they're getting along so well she prefers not to think of it if she doesn't have to.)

"Of course." She wasn't able to write it down initially (she wasn't able to do a great deal, initially), but now she isn't locked up any more. Many of her notes aren't here, they're back in her world with the rest of the enclave, but she's rewritten a great deal in her spare time here and she makes new notes as she goes, especially now that she's teaching music. She can feel it. "Now that I have a name, I'll be able to find sources, but I suppose most of them will be human in origin."

And therefore potentially useless.
