Does Honoria function as the golden girl of “Babylon Revisited”? How would you compare her to Judy Jones?
You seem to be slightly confused in this question. Hororia in this excellent story is the nine-year-old daughter of Charlie, and so is clearly not a "golden girl" in the same way that Judy Jones could be considered a "golden girl" in "Winter Dreams" or Daisy Buchanan might be in The Great Gatsby. If you are looking for a "golden girl" equivalent, you might want to analyse the character of Lorraine Quarrles and how she seems to represent the same kind of spirit of these other two characters. Honoria therefore does not really compare to Judy Jones.
Instead, Honoria is presented as a daughter who greatly loves her father and is incredibly excited to see him again. Note how she responds to seeing her father again:
From behind the maid who opened the door darted a lovely little girl of nine who shrieked "Daddy!" and flew up, struggling like a fish, into his arms. She pulled his head around by one ear and set her cheek against his.
Honoria, apart from being devoted to her father, is also very sensitive to the situation that means she is living with her aunt and uncle. She is concerned when her father offers to buy her anything she wants from the toy store, saying that "we're not rich any more," and seems unhappy when he insists. She is also a hardworking student as she is doing well at school. Honoria takes pride in her self-reliance, even though she is only nine, boasting to her fathe about "I do everything myself." She desperately wants to live with her father though she enjoys staying with her aunt and uncle.
