In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
Q: Passage: In France during the mid-17th century, Cardinal Richelieu receives a visit from the despicably charming young woman, Milady de Winter.  Milady brings the Cardinal information regarding the notorious affair between the queen of France and the English Duke of Buckingham.  Outside their window, the queen's seamstress, Constance Bonacieux, stands watching the conversation between the two characters, when she is attacked by Rochefort, one of the Cardinal's loyal men. She is rescued by the young musketeer d'Artagnan and taken away to his abode, where Constance briefly explains her troubles and asks for d'Artagnan's help.
Cardinal Richelieu, wanting to convince King Louis XIII that his wife, the queen, is unfaithful to him and in love with the Duke of Buckingham, suggests that he should ask his wife to wear the diamonds he had given her for an upcoming ball. The queen, shocked and dismayed, confesses to Constance that she had sent the diamonds to the Duke of Buckingham, and her confidant goes to d'Artagnan for help. With the help of his companions, three of the finest musketeers in France, Athos, Porthos and Aramis, d'Artagnan makes his way to England to seek the Duke himself, so that he may recover the diamonds and restore the queen's honor.
A:
What are the full names of the characters who Constance watches as they have a conversation?
