"We danced the Varsouviana! Suddenly in the middle of the dance the boy I had married broke away from me and ran out of the casino.
"....Then I heard voices say--Allan! Allan! The Grey boy! He'd stuck the revolver into his mouth, and fired--so that the back of his head had been--blown away!”
“[Polka music sounds. In a minor key faint with distance.] … A few moments later--a shot! [The polka stops abruptly.][Blanche rises stiffly. Then, the polka resumes in a major key.]
[She stares at him vacantly for a moment. Then with a soft cry huddles in his embrace. She makes a sobbing effort to speak but the words won't come.]
“You need somebody. And I need somebody too. Could it be--you and me, Blanche?"
Williams uses the imagery of light to emphasize how the truth will follow you wherever you go, no matter how hard you try to cover it up. Blanche spends most of the play hiding from any light, and makes it a priority to only be seen in the dark in order to preserve her diminishing youth/beauty. He makes sure to emphasize Blanche's “fear” of being exposed for who she truly is, as her character of a insecure and lonely woman develops.
It is very noticeable that Blanche’s mental health continues to worsen throughout the play. The motif of music is very prominent in this play as it represents Blanche’s deteriorating mental stability. She goes crazy as the intensity of the Varsouviana polka music and blue piano take over her mind as she struggles to cope with her traumatic past.
Blanche tries to manipulate Mitch into believing this new life she is so adamant to keep alive. She hopes to gain love and companionship from Mitch’s innocent/naive heart. Blanche attempts to accomplish this by feeding Mitch lies about her appearance, & makes him feel bad for her, due to her unfortunate past experience with her ex lover.
