He’d stuck the revolver into his mouth, and fired – so that the back of his head had been – blown away! [She sways and covers her face.] It was because – on the dance-floor – unable to stop myself – I’d suddenly said – "I saw! I know! You disgust me…"

– Tennessee Williams

A Streetcar Named Desire, Scene 6. Blanche recounts to Mitch the events of the terrible night her young husband Allan shot himself after she told him he disgusted her. She said this to him because she found him in bed with another man. Blanche carries a great weight of guilt over the death and feels like she was the one who pushed Allan to kill himself.
