No, you pay no attention. And I'll venture to say that you have no idea what the clip you showed was about. Marie was paying attention. The points she brought up, and the questions she asked, were appropriate and reasonable. She was in a tough position. She went to France to marry Louis when she was very young--only 14--and despite her mother's efforts, she hadn't absorbed much in the way of education. Louis had his own problems, though he was intelligent. He may have been autistic.
Again, the clip presents a Dauphine somewhat more aware than the real one was.
