Summary
Analysis
Susan replies to Juliet and says that Gilly and Billee Bee wanted the letters to exact revenge for when Sidney humiliated Gilly following the teapot incident. Rumors have been circulating that Juliet discovered the Oscar Wilde letters, and Gilly wanted to publish the letters before Sidney could. Later, Sidney sends a telegram. He believes that Isola, Kit, and Juliet all deserve medals and says he'll never leave town again.
At times like this, Sidney is forced to acknowledge the chosen family that surrounds him and recognize that they're truly there to look out for him. In this way, the novel suggests that people must constantly be reminded of who their families are and what they're capable of accomplishing.
