'Vikings' Season 4: Episodes To Cover A Massive Time Span, Actor Teases Major Power Upset

The prince is currently toughing it out alone in the Nordic wilds, but by episode 4, Ragnar's (Travis Fimmel) son will find himself at the center of the most gruesome scene Vikings has ever shot - and that's even taking into account season 2's blood eagle and Aslaug's season 3 executions.

"There were arguments all over History Channel about keeping that part," Alexander Ludwig (Bjorn) teased, according to TV Insider. "A lot of people said that it would be too graphic. Luckily, we had a champion. We had to keep it. It makes the story stronger."

The scene will appear in "Yol," and could have a little something to do with an episode 3 threat from Erlendur (Edvin Endre) and Kalf (Ben Robson). 

"Very, very nasty things happen to him," series creator Michael Hirst teased, according to TV Insider.

Check out what's in store for "Yol,"

"The Yule Log burns in the Great Hall in Kattegat and, though Floki must remain out in the cold, other visitors are welcomed, among them a Norwegian King and Bjorn, with a new partner we've met before," History teased. "Ragnar is intrigued by the beautiful slave, Yidu, but her past remains a mystery."
