Tensions build in the apartment throughout the summer. Blanche and Stanley see each other as enemies, and Blanche turns increasingly to alcohol for comfort. Stanley, meanwhile, investigates Blanche's past, and he passes the information about her sexual dalliances on to Mitch. Although Blanche and Mitch had been on track to marry, after he learns the truth, he loses all interest in her. On Blanche's birthday, Mitch stands her up, abandoning her for good. Stanley, meanwhile, caustically presents Blanche with her birthday gift: bus tickets back to Laurel. Blanche is overcome by sickness; she cannot return to Laurel, and Stanley knows it. As Blanche is ill in the bathroom, Stella fights with Stanley over the cruelty of his act. Mid-fight, she tells him to take her to the hospital - the baby is coming.
