Upon the show's return, Ragnar Lothbrok returns to Kattegat seriously ill, leading to people wondering who will succeed him as king. It seems he can trust no-one — not even his wife Aslaug, as she goes to the Seer to ask if a woman would rule if he died. Ragnar's son Bjorn orders Floki to be arrested after killing Athelstan, leaving him to face the wrath of Ragnar. Elsewhere, Earl Kalf announces he and Lagertha will rule Hebedy together but not everyone's happy about it. Some citizens object, including Einar, who is then shot in the neck with Kalf instructing his men to open fire with their crossbows. Then, as seen in our exclusive look at the season four opener, Lagertha approaches Einar with anger in her eyes.
