No dialogue is necessary. In a handful of silent minutes, Pasolini enables us to empathise with both individuals. At first, we are Joseph; we've come back to Mary, maybe after a long absence, to find her pregnant. His silent confusion is ours. We share his love for her, his thirst for answers to all the questions crowding his mind. When she fails to speak, we turn around with him to walk away.
Suddenly, through the camera's eyes, we become Mary; young, frail, dazed Mary. Mary who feels lost and above all scared. Mary who does not explain because she cannot explain. Mary who does not understand what has happened any more than Joseph does.
What Pasolini knew was that when words don't work, when speech is superfluous, you can always rely on the eloquence of silence.
