BLANCHE [uncomprehendingly]: I’m looking for my sister, Stella DuBois. I mean – Mrs. Stanley Kowalski.
– Tennessee Williams
A Streetcar Named Desire, Scene 1. Blanche finds it hard to accept that her sister is no longer a DuBois. Stella doesn’t have her own name, but "belongs" to Stanley Kowalski. This speaks to the theme of patriarchy and male dominance in the play. It also points to Blanche’s difficulty in accepting reality, preferring to live a fantasy instead.
