"Vikings" Season 4 Spoilers

A plan has been set in motion. In the Season 4 premiere of “Vikings,” Floki (Gustaf Skarsgård) asked King Ragnar (Travis Fimmel) if he was to be executed for the murder of Athelstan (George Blagden). And it looks like the shipbuilder will get his answer in episode 2 of the History Channel series.

The synopsis for the forthcoming installment, titled “Kill the Queen,” reveals that the former friends will “remain at odds in Kattegat” when Ragnar unveils Floki’s punishment. “You made me suffer and I have such a wonderful punishment for you,” he says to his shackled prisoner. “And it goes on and on and on.”

In episode 1, Ragnar revealed to his son Bjorn (Alexander Ludwig), who ordered the arrest of Floki, that he had no intentions of punishing his friend. But since Bjorn went public with Floki’s incident, he’s now forced to deal with Athelstan’s murderer.

That wasn’t the only decision Bjorn made that upset his ill father. Ragnar is also furious that Rollo (Clive Standen) has been left behind in Paris. Ragnar knows that his brother has dreams of becoming a prominent war hero and he’ll do anything to gain that title — even if it means betraying his own, which he does in the premiere episode. Rollo slaughters his fellow Vikings at the Frankia campsite and he’ll continue to go against his own in episode 2.

“Rollo makes great efforts in Paris to win over his new bride, Princess Gisla (Morgane Polanski),” the summary states. Those efforts include working hand in hand with Count Odo (Owen Roe) to construct a fixture that will keep the Vikings from infiltrating the city of Paris.

Meanwhile, Bjorn will put his “survival skills to the test” when Ragnar’s eldest son makes his way into the wilderness. After disappointing his father, Bjorn will prove to Ragnar that he is deserving of one day leading the people of Kattegat by surviving harsh winter conditions.

But Bjorn won’t be the only character facing potential death. Queen Kwenthrith’s (Amy Bailey) neck is also on the line when opposing forces in Mercia capture her. King Ecbert (Linus Roache) will then task his son Aethelwulf (Moe Dunford) with rescuing the royal before she meets her grim fate.

“Vikings” Season 4, episode 2 will air on Thursday, Feb. 25 at 10 p.m. EST on History Channel.
