I kept crossing out this chapter but the more I think about it, the more it is important for the whole storyline. The events themselves might not be, but the subtext very much is.
While I know why the Lady brought Jaune on board and what she plans with her, I am not one hundred percent certain how she feels about Jaune besides Jaune s use in her plans.
Whatever that might be and no matter if this was Jaune or anybody else: The Lady absolutelly detests people who degrade, hurt and or belittle themselves.
