I have thought about it alot, but I just can't seem to give the scene with Louise Bonner some logical meaning.
I guess she functions as a warning. But to whom? Rita, Betty or Diane?
Furthermore she says: "Someone is in my room and I want her out of there." Also: "My name is Betty.""No, that's not what she said."
Can someone explain this to me? I'm at a loss here.
