The Carrie Fisher scene
This scene had to have been made up and didn't actually happen in real life because it's so odd (although maybe not for Hollywood) and it went nowhere.
Carrie plays a religious person who picks Dawn up off the streets in a drug and prostitution area, but doesn't take her to a shelter or police station but to her apartment instead. I kept thinking they would explain this scene more, but the Carrie Fisher character never appeared again in the movie. I was waiting for her to turn back up again in another part of the movie.
