2 Questions

1. Does Moze know that Trixie is a prostitute? (Which isn't the same thing as if Trixie were just cheating on him.)
2. In the move, as opposed to the novel the film was based on, is it suggested that Moze settles down and straightens out? After all, if he is going to look after Addie on a permanent basis, he would have to settle down. By settling down, I don't necessarily mean have a permanent girlfriend or marry, but just straighten out of the life of crime.

Paper Moon does not glorify the past or engage in "cheap" nostalgia. It really demonstrates how hard times were, and what people were forced to resort to just to survive.
