Ubbe fights Frodo to decide whether the invading Vikings will accept peace and land in Wessex. The duel leaves him badly injured, but he calls on Odin and finds the strength to kill his opponent. Torvi stops another man from attacking him afterward. The surviving kings accept the settlement. Ubbe later admits that Christianity has not replaced his attachment to the gods he grew up with, even though conversion helped secure his place beside Alfred.
Judith dies, leaving Alfred to carry on without the mother who protected his rule. Lagertha joins Ubbe and Torvi in East Anglia, returning to farming and remembering the life she once shared with Ragnar. Her experience after the battle is also shown through the healer's care. In Iceland, Floki explores the cave expecting signs of his gods, only to find a Christian cross. His laughter turns to anguish before the cave shakes and falling rock traps him inside.
Freydis learns that Baldur's remains have been found and confronts Ivar, who questions whether the child was ever his. He prepares Kattegat's defenses as the forces gathering against him approach. A storm damages Bjorn and Harald's fleet, and their argument becomes a fight that Gunnhild interrupts. Hvitserk and Olaf reach the same objective from another direction. Bjorn and Hvitserk embrace, putting their earlier division aside and joining their armies to attack Ivar and take back the town their family once ruled.
