The crowd departs: (Duet, Norma and Pollione: "In mia man alfin tu sei" / "At last you are in my hands"). Norma demands that he forever shun Adalgisa; only then will she release him and never see him again. He refuses, and she vents her anger by telling him that she will then kill her children. "Strike me instead", he demands, "so that only I alone will die", but she quickly asserts that not only will all the Romans die, but so will Adalgisa, who has broken her vows as a priestess. This prompts him to plead for her life. (Cabaletta: Norma and Pollione: "Già mi pasco ne' tuoi sguardi" / "Already I take pleasure in the looks you give me".) When Pollione demands the knife, she calls the priests to assemble. Norma announces that it would be better to sacrifice a priestess who has broken her vows, and orders the pyre to be lit. Oroveso demands to know who is to be sacrificed while Pollione begs that she stays silent. Norma then wonders if she is not in fact the guilty one, then reveals that it is she who is to be the victim: a high priestess who has broken her vows, has become involved with the enemy, and has borne his children. (Aria, Norma to Pollione: "Qual cor tradisti" / "The heart you betrayed"; Duet: Norma and Pollione; ensemble, Norma, Oroveso, Pollione, druids, priests: each expresses his/her sorrow, anger, pleas to Norma, with Oroveso learning for the first time that Norma is a mother.)
