This is the third confrontation between Blanche and Stanley. Here Blanche is the witness to the animal brutality and the coarse behavior of Stanley. The violence that he perpetrates is totally alien to Blanche's understanding. But more amazing to Blanche is the fact that Stella returns to Stanley after the fight is over.
In Stella's return to Stanley when he calls for her, we see the basis on which their marriage is built. In earlier scenes it was intimated that there could be no similar traits between them. Here it becomes apparent that the basic attraction is one of pure physical sexual attractions as they "come together with low, animal moans."
What is often overlooked in this scene is the basic cause of this scene. To project, one must ask himself, would this outburst have occurred if Blanche had not been visiting there. It is apparent that Blanche's presence was the principal cause of the violence. And later it will be developed that Stanley feels her presence is an actual threat to his marriage.
The attraction between Mitch and Blanche contrasts aptly to the bestial attraction between Stanley and Stella. The sensitivity and the quietness of Blanche and Mitch emphasize the delicate basis of their relationship.
