Plot summary
Ubbe steps forward to challenge Ragnar, but instead they embrace. Ragnar asks his sons to come with him to England, but Bjorn refuses, as he plans to raid the Mediterranean with Floki, Harald, and Hvitserk. Ubbe and Sigurd promise to stay and protect their mother and Kattegat, now an important trade center. Ivar sees his brothers sharing the slave girl Margrethe, and wants her as well. After failing to sleep with her, he threatens to kill her but instead cries as she tells him that being Ragnar's son is more difficult than being a common man.
Ragnar visits Floki and tells him that he loves him. In Hedeby, Ragnar apologizes to Lagertha after she refuses to accompany him to England. Ragnar finds a large tree while riding back to Kattegat and tries to hang himself. However, ravens chew through the rope to save him. Back in Kattegat, Ragnar finds Ivar in the throne room and persuades Ivar to come with him to England.
