Plot summary
Ragnar's embassy to Jarl Borg in Götaland fails, as King Horik rejects a compromise settlement about the contested land. Driven by ambition and jealousy, Rollo agrees to support Borg against Ragnar. In Kattegat, a disease kills many inhabitants, including Lagertha's daughter, Gyda, and Siggy's daughter, Thyri. Lagertha asks the seer about Ragnar and her future but the seer refuses as he only sees misery. Underway, Ragnar meets and is seduced by the princess Aslaug; eventually, she reveals she carries his child.
