5. The Usurper

Complete story — includes the ending

The Vikings return to Kattegat, and the women learn of Torstein's death as the men learn of Siggy's. Ragnar is suspicious about why Aslaug was not watching the children. Floki becomes more outspoken about his hatred for Christians, and Athelstan. Helga tells Floki about Harbard, and he claims that Harbard is a god. Aethelwulf learns that Judith is pregnant with Athelstan's child, and he is sent to the settlement. A messenger arrives to tell Lagertha that her earldom has been usurped by Kalf; she asks Ragnar to help win it back. Ragnar tells the men that they will raid Paris in the spring. Ragnar returns with Lagertha to speak with Kalf, although he decides not to help fight for Lagertha, and instead asks him to join the raid on Paris. Aethelwulf leads his soldiers to the settlement and kills all the settlers. Floki tells Ragnar that Aslaug slept with Harbard and that Harbard is another name for Odin. King Ecbert finds out about the settlers' fate; he chides his nobles, then in private reveals that it was his plan all along.
