Donny works for the Nobles -> Chateau is a Noble -> Donny doesn't like the Nobles much -> Except for Liszt because he refers to him as "an old friend". I could say more but it spoils the later chapters^^;
Also! Old man in the past few chapters is her grandfather; Nelson is her uncle (but he doesn't know she's alive, and when Ryangha speaks about her, he probably doesn't use her name, or refer to her real last name.) Hope this clears it up a bit!
