Among all the guests were none who listened to the song more eagerly than Bertalda's noble foster-parents.
'She has sung the story of Bertalda, the little child we found so long ago,' they said each to the other. 'It was even thus we found her in the meadow, among the flowers.'
And Bertalda herself cried out in haste, 'Undine, Undine, you know my parents, bring them to me, bring them to me, I entreat you!'
Then Undine, with tears that were tears of joy in her eyes, looked at Bertalda, and said softly, 'They are here, your parents are here, dear maiden, and when you see them you will rejoice. Well do I know the tender care they will give to you, for it was even they who were my own foster-parents.'
At a sign from Undine the old fisherman and his wife now stepped forward from the corner in which their foster-child had bidden them wait. It was she, Undine, who had sent for them that they might claim Bertalda, who was, as Kühleborn told her, their child.
The eyes of all the guests were fixed in astonishment on the humble fisherman and his wife. Could these poor working folk be indeed the parents of the maiden who stood before them, so cold, so full of pride?
'Yes, here is your long-lost daughter,' said Undine softly, as the old people stood bewildered before Bertalda. Then they, taking courage from her words, threw their arms around their daughter. And as they embraced her, tears streamed down their old worn faces, while they thanked God for His goodness in giving them back their child.
But Bertalda tore herself from their arms. She, the child of a poor old fisherman and his wife! She could not believe it. She did not wish to believe it. In her pride she had hoped to be known as the daughter of a beautiful princess, or even of a queen. Now in her anger she believed that Undine had brought the fisherman and his wife to the banquet only to crush her pride and to humble her before Huldbrand and his guests.
The angry maiden took no pains to hide her rage. She reproached Undine, Undine who had only wished to give her joy, nor had she any words too bitter to fling at the fisherman and his wife.
And Undine, who had hoped to make her friend and her foster-parents happy, listened sadly, now to Bertalda, now to the old fisherman and his wife.
'Bertalda,' she cried, 'Bertalda, do not be angry. Have you not a soul? Let it teach you not to grieve your parents more.'
