Bjorn finally decides to go rescue Harald from Olaf, leaving Ubbe behind as regent, who advocates making Kattegat greater again as home port for trade and raids on new routes, agreeing with Torvi to let the kids in Lagertha's care when they can set out after Bjorn's return. Ubbe meanwhile plans to send Hvitserk on an expedition along the Silk Road, but he's utterly tormented by visions of Ivar and his burnt-alive beloved Thora. Harald hears of his hope for liberation from dwarf jailer Canute, but Olaf's defense by oil on the coastal waters and burning arrows deals a terrible blow. Ivar further befriends boy prince Igor and is impressed how ruthless prince Oleg promises to prepare the 'reconquest' of Scandinavia and reduces his raid-captured rival brother Dir to a chained dog.
