I haven't seen Black Swan although I really want to. And since I haven't there are obvious gaps between the events. This is my interpretation of the movie from what I've read. Please don't tell me about the gaps or what did/didn't happen.
I was in the locker room taping my toes together. I understood that in order to become the black swan i'd need to go further than practice because the black swan wasn't just a part in a ballet. She was also a part of me or at least I wanted to be. I hated being my mom's 'sweet girl' being her innocent white swan. I hadn't had sex. I frequently scratched my shoulder blades which she daily checked. My shoulder blades itched because the wings were coming through them. I hadn't had sex because my mom wouldn't let me. She wouldn't let me do much of anything including breathe.
A dancer named Beth came into the locker room and began stretching. I hated she had to do that here. That's what the studio was for. She was so perfect. So good. And she knew she was good.
So did everyone else.
Beth was beautiful and thin, with dark hair, pale skin and huge dark eyes.
The other reason my mom wouldn't let me have sex was because she was jealous. She didn't want me to be with anyone but her.
Over time my mom had begun painting me. I know how twisted that is. But you don't just abandon your own mother no matter how crazy she is.
I finished taping my toes together then took off my earrings and put them back on. I did this several times partially to reduce my own anxiety and partially to symbolize what my mom had been doing to me.
After stretching for several minutes Beth left leaving her earrings on the carpet. The locker room was now empty. I went and picked her earrings up from the floor slipping them into my ballet bag.
I did this because I was jealous of her.
I then went into the ballet studio.
