As the Vikings carry their ships overland, Harald and Halfdan kill a Frankish family. Lagertha has a miscarriage and is comforted by Ragnar. Aethelwulf and Alfred arrive in Rome, and the Pope makes Alfred a consul. In Wessex, Ecbert is crowned King of both Wessex and Mercia. King Aelle is displeased when Ecbert tells him they are no longer equals. In Kattegat, Sigurd discovers Siggy dead; he tells a drunken Aslaug, who shrugs off her death, and jokes with Ivar. In Paris, Charles appoints Roland its protector. The Vikings arrive outside Paris. Erlendur tells Torvi she must kill Bjorn, or he will kill her son; she approaches Bjorn with Erlendur's crossbow, but instead turns and kills Erlendur.

As the Vikings sail for Paris, Ragnar mutters that he must kill Rollo.
