Life in Kattegat seemingly goes on normally. Floki and Helga have a daughter though Helga isn't too keen on the name he chooses for her. Bjorn continues to pursue Porunn but she tells him that as she is now a free woman, she can make her own choices. Ragnar continues to explore Athelstans belief system. King Horik's wife and younger children arrive in Kattegat but it soon becomes clear that he is plotting against Ragnar. Horik demands proof of Floki's loyalty, and he complies. Horik tells Siggy that her task will be to kill Ragnar's young sons. As more of Horik's warriors arrive, it appears that Ragnar has been caught out. Not quite so, however.
