Daddy knows that Brick's story is "half-assed" and wonders he has left out. A phone rings in the hall. Glancing toward the sound, Brick confesses that Skipper made a drunken confession to him over the phone, and Brick hung up on him. They never spoke again. Daddy has his answer, that Brick's disgust with mendacity is disgust with himself. He dug his friend's grave before he would face the truth.
Brick challenges Daddy and asks whether he can face the truth. What about the birthday congratulations when everyone knows there will not be any more. Whoever has answered the phone laughs shrilly, "No, no, you got it all wrong! Upside down! Are you crazy?"
Realizing his disclosure, Brick attempts to get Daddy to join the party. Daddy grabs his crutch as if it were a "weapon for which they were fighting for possession." He orders Brick to finish what he was saying. Brick asks that he leave the place to Mae and Gooper. Everyone has lied to him: he has cancer. "Mendacity is a system that we live in," declares Brick. "Liquor is one way out an'death's the other." He swings out the gallery door.
Hoarsely Daddy calls for Brick. He reappears and apologies. He no longer understands how anyone could care about anything but liquor. Perhaps being "almost not alive" makes him "accidentally truthful." "You told me! I told you!" he declares.
A child bursts in with a fistful of firecrackers screaming "Bang!" repeatedly. Revolted, Daddy curses the liars about him, all "lying dying liars." He moves out; a child is slapped in the hall and bawls hideously.
Here Daddy finally forces Brick's confession and receives his own "inadmissible thing" in return. This showdown reveals the nature of the love between them.
