brangaene returns to isolde to tell her about what was said. isolde sadly tells her how, after morold had died, a man called tantris had been brought to her because he was seriously injured, and that she had made him better using her powers of healing. however, she then found out that his real name was tristan. he was ireland’s worst enemy, and he was the man who had killed morold. isolde had tried to kill him with a sword, but when tristan had looked into her eyes her heart had become full of love and she had dropped the sword. tristan had been allowed to go back to cornwall. however, it seemed now he had told his uncle, king marke, all about the beautiful isolde and had come to get her so that his uncle could marry her. brangaene tries to make isolde see that tristan is doing an honourable thing to make her queen of ireland, but isolde will not listen. she is furious, and wants him to drink a potion which had been intended by her mother for king marke and isolde as a love potion, but for tristan it would be death.
