I read the book and that little bit was inordinately disturbing, only a few brief sentences. There was Julie, working as an assistant to the madame (NOT a prostitute), maybe doing the books, and they saw each other and each got a rude shock. Then Julie scurried away, and that was that. There was no conversation, no explanation as to how or why she ended up as she did....Myself, I think her husband died, was killed, or in jail and unable to protect and provide for her any more, so she took what work she could find. But she was not a prostitute, just worked in the bordello.
I was giving examples of things that might have happened to a woman in her situation.
However, threads like this are rampant on IMDB and make absolutely no sense. How can anyone clarify what happened to Julie after if Hammerstein didn't write it? It's not defined so there are no specifics. That stuff happened to book Julie. But movie Julie's fate is an question mark and no one can answer it. And book Julie and movie Julie are two different characters.
