cahn

That's highly interesting, that Fritz assumes FW is cool with Duhan being employed by Charlotte (or rather her mother-in-law), but not by Wilhelmine. Though it makes sense, because Wilhelmine is seen as a culprit in the great crime of Fritz education, and Charlotte is not.

Wilhelmine asking for Duhan, btw, confirms that she liked and respected him for his own sake, not just as a "keeps Fritz from boyfriends people who aren't me bad influence" factor.
