'Vikings' season 5B: Is Magnus really the son of Ragnar Lothbrok?
There isn't any proof Magnus is the son of Ragnar Lothbrok and a quick look up of historical facts reveals there was no Magnus in Ragnar's nor Queen Kwenthrith's legacy
MEAWW published an exclusive clip of Bjorn Ironside making an unlikely ally in episode 13 of 'Vikings' season 5b, and as it turns out, it was none other than Magnus, an alleged son of Ragnar Lothbrok and Queen Kwenthrith. His name is not unheard of, and the discussion of Magnus being that one particular son of Ragnar who will kill Lagertha, as prophesized, was also speculated on by fans soon after season 4.
