Beowulf agrees to the deal and returns to Heorot, claiming that she has been slain by him. Hrothgar, however, realizes the truth and indirectly tells Beowulf that many years before, he was seduced by Grendel's mother, and Grendel was the product of their affair. Beowulf is then crowned King of the Danes, much to the dismay of Unferth (John Malkovich), Hrothgar's adviser. The king kills himself by jumping off the castle and on to the beach. His body is then washed away by the sea.
