Tatyana falls in love with Onegin. She writes him a letter pledging her love to him and telling him that she "is his." But Onegin rejects her in a polite, but cold and condescending sermon. Instead, angered by Lensky's dragging him to Tatyana's nameday party, he asks Olga to dance and flirts with her, much to Lensky's displeasure. Lensky challenges his friend to a duel with pistols. Seconds are appointed and, opportunities for reconciliation scorned, the duel takes place. Onegin kills Lensky and leaves the country estates to take a distant military assignment. Tatyana has disturbed dreams of Onegin and visits his uncle's estate to scan the books that he was reading so as to judge his character.
