Miss Frederica
Frederica is not a character in the novel who participates much in events, but still an image of this young lady is given rather precisely: “A girl of sixteen who has received so wretched an education, could not be a very desirable companion here; She has not even manners to recommend her, and is equally dull and proud”. Thus we see that Frederica is a person who lacks qualities that would make her a desirable girl in society, but this image is mostly created by her mother, and when the girl visits Churchhill she appears completely different, as Catherine says: “There cannot be a more gentle, affectionate heart, or more obliging manners when acting without restraint”. Until the end of the story Frederica proves to be a completely different person from the character who was described at first.
Lady Susan
This is an image of lady Susan given by Catherine Vernon: “She is really expressively pretty; she is delicately fair, with fine grey eyes and dark eyelashes, and from her appearance one would not suppose her more than five and twenty; she possesses an uncommon union of symmetry, brilliancy, and grace” From these words, Susan Vernon might be considered a very beautiful woman, which she was indeed. However, through this character's example, the author portrays that it is not appearance that matters.
Reginald de Courcy
This is a description of Reginald given by lady Susan: “a handsome young man who promises me some amusement. He is lively, and seems clever.” Reginald is really a well-bred, interesting young man, but because of his naivete gets into the webs of lady Susan.
