Scene 10: Delusion vs Reality
This scene shows Blanche at her most delusional state. She's created an imaginary wealthy suitor from Dallas, complete with elaborate backstory, showing just how desperately she needs to escape reality. Stanley brutally shatters these fantasies by reminding her there's "nothing but imagination."
The symbolism becomes darker and more threatening. Grotesque shadows and lurid reflections on the walls represent Blanche's descent into madness and show how her world has become hostile and nightmarish.
Costume changes reveal the complete power reversal. Blanche now wears soiled, crumpled white - her purity and elegance destroyed. Meanwhile, Stanley appears in expensive silk pyjamas, showing he's now the one in control.
Blanche's dialogue becomes increasingly fragmented and desperate. Her superior attitude ("sitting on your throne") gives way to helpless cries, showing her psychological breakdown as reality finally overwhelms her delusions.
Remember: Williams uses every element - costume, lighting, sound - to mirror the characters' internal states and the play's central themes.
