The dispute starts again with increasingly dramatic tension: Santuzza beseeches Turiddu not to abandon her but, irritated, he repulses her and, after having flinging her to the ground, runs into the church. Furious for this humiliation, the young woman damns him, wishing him a “bad Easter”.
Alfio arrives and Santuzza, driven by her anger and a desire for revenge, discloses the affair that Turiddu has with his wife: the couple meets in his house while he’s at work. Initially, the man is incredulous and threatens to kill her if she is lying. Then he becomes convinced. Santuzza immediately regrets what she has done and would like to retrace her steps, but it’s too late. Alfio swears revenge.
After mass, the congregation leaves the church, and a group of men stop at the tavern. Turiddu invites his friends for a toast and, amidst the merriment, Alfio arrives and, with a grim face, coldly refuses the invitation to drink. Immediately understanding the situation, Turiddu pours the wine on to the floor, chilling the onlookers. While the frightened women draw back, the rivals embrace and, following the rural code of honour, Turiddu bites Alfio’s right ear, challenging him to a duel. He then admits to being in the wrong and to deserve to die, but he will not let himself be killed as he has obligations regarding Santuzza. Impassive, Alfio sets their appointment behind the orchard.
Before following his rival, Turiddu says goodbye to his mother. He asks her to bless him, as she did when he left for his military service, and to take care of Santuzza if he doesn’t return. Lucia doesn’t understand the reason for these phrases, but the boy gives no explanation, just kisses her repeatedly and runs off. Santuzza arrives and embraces Lucia, who tries to follow her son. A few moments later, an indistinct murmuring is heard, broken by a scream of horror: “Turiddu has been killed!”
