Blanche announces that she should never have called Mitch and that she doesn't need to take insults from a man like him. Stanley begins to complain about the lingering heat from Blanche's steam bath, and she snaps that she has already apologized three times. She says that a healthy Polack like Stanley wouldn't understand her need to calm her nerves. Stanley angrily retorts that Polish people are called Poles, not Polacks, and that he is "one hundred percent American."
The phone rings, and Blanche tries to answer it, expecting Mitch. Stanley intercepts her and speaks to the caller, one of his bowling buddies. While Stanley speaks on the phone, Stella touches Blanche on the shoulder. Blanche, confused and angered by Stella's unexplained pitying behavior, tells Stella to back off. Stanley erupts, yelling for Blanche to be quiet. She tries her best to control herself as Stanley returns to the table. With a thin veneer of kindness, Stanley offers Blanche a birthday present. She is surprised and delighted—until she opens it and sees that it is a one-way ticket back to Laurel on a Greyhound bus, leaving Tuesday.
The Varsouviana music begins to play as Blanche tries first to smile, then to laugh. When her efforts fail, she runs to the bedroom and then to the bathroom, clutching her throat and making gagging noises as if Stanley's cruelty has literally taken her breath away. Stanley, pleased with himself and his actions, prepares to go bowling. But Stella demands to know why Stanley has treated Blanche so callously. She admits that much about Blanche is insufferable, but argues that Blanche's naïve trust and kindness have been abused over the years, and that the current Blanche is the product of suffering. He explains that Stella thought he was common when they first met, but he took her off her pedestal, and things were wonderful until Blanche arrived and made fun of him. As he speaks, a sudden change comes over Stella, and she slowly shuffles from the bedroom to the kitchen. After a minute, Stanley notices that something is wrong and cuts his diatribe short. Stella quietly asks to be taken to the hospital. Stanley is with her in an instant, speaking softly as he leads her out the door.
In Scene Eight, Stanley, Blanche, and Stella become increasingly short-tempered. Stanley shows that he has taken all that he can handle of Blanche and will allow Stella to sway him with her protestations no longer. He is intent on removing Blanche from his house, and he sees no need for delicacy or kindness in doing so. However, Blanche too seems to have reached the limit of her capacity for niceness. She loses her temper briefly when she snaps to Stanley that she has already apologized three times for her bath. Her outburst constitutes the first time Blanche openly express anger in the play.
Stella too becomes increasingly assertive as she begs Stanley to explain his contempt for Blanche and to attempt to understand Blanche's nature. She insists that Stanley not leave to go bowling and demands an explanation from him for his cruelty to Blanche. These actions constitute the greatest assertion of independence Stella makes toward Stanley throughout the entire play. As Stella grows angrier, her grammar becomes more formal, and she uses words such as "needn't." Stanley's grammar, on the other hand, grows sloppier, and he begins to speak in sentence fragments. The language Stella and Stanley use indicates their respective retreats away from each other into their social roles. But just when Stella seems to be thinking independently from Stanley and reasserting her connection to Blanche in her outrage at Stanley's cruelty, she goes into labor. The baby reasserts Stella's connection to Stanley and makes Stella dependent on him for help. He is once again in control as he takes her to the hospital.
Stella does not recognize that her own similarities with Blanche. Her comments to Stanley as she begs him to understand Blanche's situation show that she views Blanche with pity. Yet, when making her case to Stanley, Stella argues that Blanche was trusting in her youth until "people like you abused her." Even though Stella recognizes that Blanche was worn down by "people like" Stanley, she does not reject him or realize that she could wind up in Blanche's place. Stanley, however, reminds Stella of her similarity to Blanche when he points out that he had to pull Stella down from the columns of Belle Reve.
Stanley's discussion of his and Stella's relationship as a response to Stella's demand to know why he is so cruel to Blanche seems strange. He begins by asking Stella if she remembers when she found him "common," and states that after he pulled Stella down from the columns of Belle Reve, he and Stella were happy to be "common" together until Blanche showed up. The implication of Stanley's speech is that he desires to take ownership of people and things, like Blanche and Stella, that make him feel inferior. What Stanley doesn't understand is how precarious and insecure the once majestic world of Belle Reve was by the time Stella and Blanche were born. His actions toward Blanche are all the more cruel because he misunderstands how weak Blanche is to begin with. Stanley's desire for ownership manifests itself as the furious sexual desire he displays for Stella in the play. The heated passion of Stanley's marriage foreshadows his enraged violence toward Blanche, which also expresses his need for ownership, but in a different form.
