Norma looks at both of her sons, who are asleep. She considers killing them. Advancing towards them with knife upraised, she hesitates. (Recitative: "Dormono entrambi ... non vedran la mano che li percuote" / "They are both asleep ... they shall not see the hand which strikes them.") But she cannot bring herself to do it: (Aria: "Teneri, teneri figli" / "My dear, dear sons") The children wake up and she calls for Clotilde, demanding that Adalgisa be brought to her.
