omg i love her okay 🥺 can katharina please visit the library and touch all the stuff... she's very knowledge-hungry and spends a lot of her spare time reading, and she'd be very interested in any books on magical philosophy or cosmology etc. she'd respect the rules and maybe even would be slightly less weird than usual because it's ysabel's turf. i mean obviously if the opportunity arose she'd give ysabel the ol double-handed handshake, european cheek kisses, intense eye contact "would you like to be seduced into my cult" katharina treatment but that opportunity would have to open up, she wouldn't do it out of the gate LOL and i think she'd very much respect ysabel's expertise and knowledge base.
