Vikings season 4
Ragnar plans to handle unfinished business in Wessex with King EcbertHistory Channel

Vikings season 4 returns on the History Channel on 30 November with episode 11 titled The Outsider. The periodical drama will focus on the power shift in Kattegat as King Ragnar Lothbrok has returned after years following the Paris battle.

The once powerful king of the Norsemen is now a disgraced man in Kattegat as he lost all respect after he fled the warfront when he was being defeated by his own brother Rollo. His gutless act resulted in the Norsemen's defeat against the Parisians.

The mid-season premiere will bring forth Bjorn's dilemma – who is ruling Kattegat – as he hates his father, but with his sudden arrival will be forced to choose between his kingship or the disgraced king.

Alexander Ludwig, who plays Lagertha's son, teased that Bjorn's story will leave fans mesmerised. "I couldn't be more excited for the audience to see what's going to happen, because it's going to blow their mind," he told Toronto Sun.

Episode 11 will focus on the disgraced king's tactics as he finds a way back into his people's heart because they are unwelcoming of him and hence the titled The Outsider.

The synopsis of the episode reads as follows: "In the midseason premiere, Ragnar's reappearance in Kattegat triggers a chain of events no one – except the Seer – could have ever imagined. He unexpectedly arrives home to see what has become of his sons and to handle unfinished business in Wessex with King Ecbert (Linus Roache). Meanwhile, Lagertha (Katheryn Winnick) plans a power play in Kattegat and Bjorn (Alexander Ludwig) prepares to fulfill his long-held dream to explore the Mediterranean in a sleek new boat built for him by Floki (Gustaf Skarsgård)."

Show creator Michael Hirst had previously hinted that the series based on the mythological Norse heroes, will focus on Bjorn Ironside as he plans to sail through continents, while Ivar the Boneless (Aslaug's grown up son) will rule Kattegat.

"We've propelled 'Vikings' to the topmost level of historical drama as we follow storylines inspired by real life events such as Bjorn Ironside sailing through the Mediterranean and Ivar the Boneless becoming the most feared warrior of all time. It's not a story of one man, but a saga of Ragnar and his sons," Hirst told Variety in September.
