Cast Season 5: Vikings

By the time Vikings reached its fifth season (airing in two parts in 2017-2018), the show had undergone a seismic shift. The death of Ragnar Lothbrok in Season 4 officially passed the torch to his sons. Season 5 doubles down on this generational war, splitting the narrative (and the cast) into two warring factions: the followers of Ivar the Boneless and the alliance of his brothers.
