Some time later, Brunhild and Gudrun quarrel while washing their hair in the river. Brunhild says that she does not want the water that passes through Gudrun's hair to touch her own, because her husband Gunnar is braver. Gudrun replies with Sigurd's deeds of killing the dragon, but Brunhild says that only Gunnar had dared to ride through the wall of flame. Then Gudrun reveals to Brunhild that Sigurd was the one who rode through the wall, producing Brunhild's ring as proof. Brunhild then encourages Gunnar to kill Sigurd, which eventually he does. Once Sigurd is dead, Brunhild kills herself, and is burned on the same pyre as Sigurd. It is possible that Snorri's account of the quarrel between Brunhild and Gudrun derives from a lost Eddic poem.
