"I wish for nothing more than to be free of my gilded cage."
The Prince says this to Danielle after being struck down by her apples. It's a statement showing that though he is royalty he wishes nothing to do with it as his desire is to be free of the confines of the palace and the crown.
"Jacqueline, dear do not speak unless you can improve the silence."
Rodmilla says this to Jacqueline after she answers for her sister Marguerite, who has just exploded at a servant. She gives the correct answer to her mother who is attempting to teach Marguerite how to speak as a lady, but ironically when Jacqueline speaks she doesn't want to hear from her. It shows that Rodmilla clearly has a favorite.
"The Prince has read Utopia."
Danielle learns that Prince Henry has read the final book that her father gave her before his death, Utopia. It is a book she reads every night, and once we discover that the Prince has read it as well we understand that there is a connection between the two characters that is deeper than we could have gleaned from the surface.
