You know she’s been feeding us a pack of lies here?… But now the cat’s out of the bag!… I already suspected. But now I got proof from the most reliable sources.
– Tennessee Williams
A Streetcar Named Desire, Scene 7. With Blanche in the bathroom soaking in a hot tub, Stanley announces his big reveal to Stella. He has definitive proof of Blanche’s lies and pretense. He uses the animal imagery of a cat metaphor to explain that Blanche’s secret is exposed. This is a very big moment in the play, as Stanley sets about dismantling Blanche’s facade to show the reality behind the world of fantasy she constructs around herself.
