Mitch is the "object of desire" through which Blanche, our protagonist plot, hopes to find fulfillment. As she settles in at the Kowalski place, her budding romance is her chance for a better future.
Blanche gets her hooks into Mitch.
It’s clear that Mitch returns Blanche’s feelings, which means the chance of marriage and escape from her past life is definitely possible.
Stanley gets violent—and suspicious.
The famous "Stelllahhhhhh!" scene may be hot for Stella, but it’s definitely frustrating for Blanche, who can’t understand her sister’s desire for the aggressive Stanley. Things really start to go wrong when Stanley mentions his friend who travels through Laurel, Blanche's hometown, and heard some bad stuff about Blanche. This threatens her "dream" of marrying Mitch.
Stanley brings the truth to light; Mitch rejects Blanche.
Just when things were going well, right? Actually, things were never going well. Blanche’s entire relationship with Mitch was always founded upon lies and fantasy, which means we’ve known this moment was coming from the start.
Destruction Or Death Wish Stage
Stanley rapes Blanche.
The "destruction" here is not only a physical one, but mental as well. Stanley’s act of violence is basically the straw that breaks the camel’s back, and he sends Blanche over the edge. Think of Scene Eleven as the aftermath to this destruction—we see the devastating effects of the violence.
