Back in her dressing room preparing for the final act, the dying of the
White Swan, Nina is interrupted by a knock at her door. She opens it to see
Lily, who has come to congratulate her on her performance as the Black Swan.
Nina realizes her fight with Lily was another hallucination, but sees the
mirror is still shattered. She notices a wound on her body and realizes that
she stabbed herself, not Lily. Back on stage, Nina dances passionately and
seamlessly as the White Swan. In the last moments of the ballet, when the
White Swan throws herself off a cliff, she spots her mother weeping in the
audience. The theater erupts in thunderous applause as Nina falls. As Thomas
and the rest of the cast enthusiastically congratulate her on her
performance, Lily gasps in horror to see that Nina is bleeding. Though Nina
lies wounded and perhaps dying, she is content and satisfied with her
performance. The film closes with Nina staring up at the stage lights while
whispering "I felt it - Perfect - It was perfect,"[3] [4]as the screen fades
to white and the audience chants her name.
