While Ivar is learning from Floki, he sees various children playing and wants to join them, so Floki puts him in his cart and takes him out among them. Floki seems to bond with Ivar, as they are fellow outcasts. Ivar later was brought to Floki by Aslaug to be mentored in the path of a Viking, with Aslaug intending for her son to hate the Christians. Ragnar said he loved Ivar as much as Aslaug, to which Aslaug replied he did not act like it. Aslaug stated that Ivar was not like Ragnar and her responsibility, not his. Ivar refused and Aslaug took him away from Ragnar. Ragnar attempts to involve Ivar in the celebration of Yol and hang a piece of mistletoe as an ornament. He said goodbye to Bjorn and he told them to take care of Ragnar. Later he was greeted by Bjorn who just came back from Paris and later in the episode. Ivar was seen when he was playing with his brothers in Kattegat while being carried in a cart which Ivar tells them not to break his bones. When Harbard left he claimed to have taken some of Ivar's pain into himself and that Ivar would not suffer as much in the future. Later Harbard seemed to be able to ease Ivar's pain through unknown means. Ivar was tormented with pain, but Ragnar did not appear to care much. When Aslaug told Ragnar his name, Ragnar gave him the epithet "Boneless." However, Ragnar could not bring himself to do so. Ragnar once took him out in an attempt to kill him himself. Ragnar, as well as Siggy, suggested that Ivar should be killed, though Aslaug refused. When he was born, Aslaug and Ragnar feared for his difficult life. Because Ragnar did not heed her warnings, Ivar was born with weak bones, his legs twisted and seemingly broken, hence the nickname "Boneless." Aslaug had warned that they should not have sex for at least three days, knowing of a prophecy that threatened the prospective child's health, but Ragnar insisted. Conceived after his father's return from England, Aslaug had been giving Ragnar warnings of things to come.
