Betty's audition line is actually what Diane experienced when she was a child. In the line, Betty said: "You are my dad's best friend...you will go to jail", and the old man he told the play said: "Don't stop". One hand touched Betty's ass, and then Betty said, "I'm going to kill you..." The old man replied grimly, "You'll go to jail..." In other words, young Diane didn't have any The way to resist the sexual assault of the father's good friend, neither complaining to the parents nor killing the strange sorrel.
After Betty and the old man's audition ended, a producer next to him commented that the story "It was forced maybe, but still humanistic." Isn't this the general attitude of society? Isn't that the reason why Diane's painful experience could not be made public, so she had to suppress it in her heart and vent it through her dreams?
From this perspective, we can solve the mystery of the blue key. In the fantasy, Betty buys a murder to kill, the hired killer said to Betty that you will get the blue key after the event is completed, and Betty asked: "What can you use this key to open?" The killer smiled and said nothing. In the end, after Betty opened the blue box with the blue key, what came out? What is that thing buried in the deepest part that even in a dream you don't want to face? Not Camilla, whom she was jealous of, but her aunts! Aunt and parents are chasing Betty! Diane couldn't stand the fear, and suddenly came back to reality and shot herself to death.
