What interrupts Brick's attack is Dixie's entrance, one of the play's many—to use Williams's terms—"incongruous" but "perfectly timed" interruptions from off-stage. Dixie returns us to Maggie's plight. This grotesque, monkey-like child embodies what Maggie lacks. As she jeers, Maggie is childless, saying that she probably cannot even have babies.

Here Maggie makes her sad, resolute pledge: to bear a child by a man who despises her. Maggie believes that her child would make good on her lack, assure her place in the family, and save her marriage. Thus Act I leaves us with a disaster that remains for a time in suspense. Donning her public face, Maggie turns to meet the family.

Before proceeding with Daddy's birthday party, however, we should also here how Maggie would serve as intermediary for the love between men in a different triangle, one involving Brick and Big Daddy. Here Maggie gives Daddy with a gift in Brick's name, a gift with which Brick will have nothing to do with. We will see this structure repeated in her gift of the child.
