The Promise

A Knight Accepts the Bond
Knowledge and Affection
Sir Huldbrand learns that Undine has gained a soul through their marriage. She tells him that she can return to her parents if he rejects her, rather than bind him by deception.
He embraces her and promises never to forsake her. The pledge gives both characters a hopeful basis for life beyond the peninsula.
A Future Test
The promise is made before Sir Huldbrand experiences repeated conflict with Undine’s relatives. His confidence in the marriage will weaken as the supernatural begins to interfere with ordinary life.
The vow is thus both a genuine act of love and a standard against which his later conduct can be measured.
The Castle’s Unease

An Uneasy Husband
A Growing Attraction
Sir Huldbrand’s affection for Undine fades as his attention turns to Bertalda. Although he feels remorse when Undine suffers, kindness does not restore their earlier intimacy.
He supports Bertalda’s imperious behavior and lets his wife submit in sorrow. The pattern shifts power within the household while leaving the marriage formally intact.
A Convenient Explanation
Sir Huldbrand blames the disturbances on Undine’s supernatural kin. He regards his own marriage as the source of trouble rather than examining his resentment.
His self-justification makes later anger easier. Instead of treating Undine’s warnings as acts of care, he increasingly experiences them as restraints.
The River’s Provocation

Resentment Becomes Action
Disturbances on the Water
Kuhleborn repeatedly disrupts the travelers’ journey toward Vienna. Undine calms the water, but Sir Huldbrand grows tired of needing her intervention.
He thinks he is becoming a prisoner of the marriage and of the closed fountain at home. The thought ignores Undine’s own vulnerability and the protections she has created.
The Coral Necklace
After Bertalda’s necklace is stolen, Undine offers a coral replacement. Sir Huldbrand throws it away and insults her in the very setting where she asked him not to scold her.
The action breaks the marriage’s protective condition. Undine leaves, and the knight’s immediate grief arrives only after he has made reconciliation impossible.
The Second Betrothal

Desire Returns
A Widower’s Household
Sir Huldbrand and Bertalda live quietly at Ringstetten Castle after Undine vanishes. At first, both mourn her and nearly forget their earlier attraction.
As time passes, grief becomes less acute. The fisherman’s arrival forces Sir Huldbrand to confront the possibility of losing Bertalda too.
A Warning Refused
Father Heilmann says Undine may still be alive and begs the pair not to marry. The three listeners sense the truth of his warning but choose to proceed.
Sir Huldbrand’s second engagement is not free of knowledge or doubt. It depends on setting aside a danger he has been explicitly asked to take seriously.
Death at the Wedding Bed

The Consequence of the Reopened Fountain
A Veiled Visitor
Bertalda’s wish for fountain water leads servants to remove the stone seal. Undine emerges and reaches Sir Huldbrand’s room, where he recognizes that his death is at hand.
He asks not to see a hideous face, but Undine reveals the beauty he remembers from their courtship. She offers the final intimacy he has long abandoned.
The Knight’s End
Undine holds and kisses Sir Huldbrand until his breath stops. He dies in an embrace shaped by love, betrayal, and the elemental law he had ignored.
His fate completes the moral arc from a freely given promise to a second marriage made against warning.
