Leaving Aífe pregnant, Cú Chulainn returns from Scotland fully trained, but Forgall still refuses to let him marry Emer. Cú Chulainn storms Forgall's fortress, killing twenty-four of Forgall's men, abducts Emer and steals Forgall's treasure. Forgall himself falls from the ramparts to his death. Conchobar has the "right of the first night" over all marriages of his subjects. He is afraid of Cú Chulainn's reaction if he exercises it in this case, but is equally afraid of losing his authority if he does not. Cathbad suggests a solution: Conchobar sleeps with Emer on the night of the wedding, but Cathbad sleeps between them.
