Plot
Ragnar and King Ecbert both experience separate visions of Athelstan, who relays the words "Mercy". Rollo attempts to learn the language of his new home, while enduring more of Gisla's mistreatment. Kalf hires a Berserker to assassinate Bjorn on King Horik's son's behalf. Bjorn obsesses over killing a bear that has managed to escape his traps. Floki and Helga struggle to cope with the death of their daughter. Ragnar approaches the cave with an axe, tells Helga that she has suffered enough and frees Floki. Lagertha sleeps with Kalf and he tells her he loves her – however she fails to reciprocate. Aethelwulf has returned with the rescued Queen Kwenthrith and her son Magnus. Judith's obsession with Athelstan continues. Wessex continues preparing its soldiers, Count Odo readies a defense of Paris, and Ragnar cleans fish giving the impression that he is not ready to resume exploring distant lands.
