Royal Librarian is awesome indeed! And why am I not surprised by Fritz' opinion of the Margrave?

(I mean, he's solidly suspiciously neutral in his letters to Wilhelmine, other than - during the time she travels in France - advising her to not mind if her butterly visits other flowers because that is the nature of a butterfly. But yeah. When has Fritz ever liked the s.o. of someone he cares about who is supposed to love him first and foremost?)
