Mime says to Siegfried that he should be thankful to him for looking after him as a child and bringing him up. He has never told Siegfried who his parents were (they were Siegmund and Sieglinde, both now dead). Siegfried does not understand anything about how babies are born. He has never seen a woman before. He only knows Mime who is pretending to be his father. Siegfried has noticed that young birds look like their parents and he asks Mime why he does not look like him. In the end Mime is forced to tell Siegfried about his parents and about the sword that was smashed by Wotan. Siegfried tells Mime to forge (make) the sword so that he can kill the dragon. Siegfried goes off.
