Outside the dragon’s cave Wotan, still disguised as a wanderer, meets Alberich (Mime’s brother who has not been in the story since the first opera).
Alberich hates Wotan for having snatched the ring from him.
Wotan does not care, and even wakes the dragon up, but the dragon does not want to fight them.

Mime and Siegfried appear.
Siegfried is not frightened at all.
He just wants to know where the dragon’s heart is so that he can kill it.
Mime leaves him alone.
Siegfried sits down in the forest and thinks.
He is glad to know now that the ugly Mime is not his father.
He hears a bird singing and he tries to imitate the bird’s song with a pipe he has made from a reed.
He blows his horn and the dragon appears.
Siegfried plunges the sword into the dragon’s heart.
Siegfried instinctively puts his hand in the dragon’s mouth and tastes its blood.
Suddenly he can understand what the bird is saying.
The bird (originally sung by a boy but normally now by a woman) tells him to take the ring and the tarn helmet (which allows the wearer to change shape or make himself invisible).
He takes them.

Mime and Alberich appear.
They are arguing about who shall have the ring and the tarn helmet.
Siegfried appears with both.
Mime offers Siegfried a drink which is drugged.
The bird warns Siegfried not to drink it.
Siegfried kills Mime by chopping his head off with the sword.
The bird then tells Siegfried about his beautiful bride Brünnhilde who is lying on a rock, protected by fire, waiting to be rescued by him.
