Brangäne returns to Isolde to relate these events, and Isolde, in what is termed the "narrative and curse", sadly tells her of how, following the death of Morold, she happened upon a stranger who called himself Tantris. Tantris was found mortally wounded in a barge ("von einem Kahn, der klein und arm") and Isolde used her healing powers to restore him to health. She discovered during Tantris' recovery, however, that he was actually Tristan, the murderer of her fiancé. Isolde attempted to kill the man with his own sword as he lay helpless before her. However, Tristan looked not at the sword that would kill him or the hand that wielded the sword, but into her eyes ("Er sah' mir in die Augen"). His action pierced her heart and she was unable to slay him. Tristan was allowed to leave with the promise never to come back, but he later returned with the intention of marrying Isolde to his uncle, King Marke. Isolde, furious at Tristan's betrayal, insists that he drink atonement to her, and from her medicine chest produces a vial to make the drink. Brangäne is shocked to see that it is a lethal poison.
