'Vikings' season 4 premiere spoilers: Can Bjorn actually kill his uncle?

The repercussions of Rollo's (Clive Standen) betrayal will be felt when "Vikings" returns for its fourth season, but it will not only be exclusive to him and his brother Ragnar (Travis Fimmel). 

Previously, Rollo betrayed his brother Ragnar by agreeing to connive with the king of France in exchange for power, land, and a bride with noble blood. This put Ragnar's life in danger, which in turn made the king's eldest son Bjorn Ironside really angry.

Actor Alexander Ludwig earlier told Zap2it that his character Bjorn would likely make his uncle pay for his betrayal even if he was very close to Rollo when he was growing up. 

"He's so hurt and he's going to kill him," he said. "In his eyes, there's certain things you can't forgive."

While admitting during the interview that he had yet to learn where season 4 would take Bjorn, the actor seemed to be pretty sure that his character would retaliate since his father almost died because of Rollo's selfishness. He also said that while negotiations with Rollo could still be possible, he believes that nothing would be enough to pacify Bjorn's anger.

"The fact is he turned his back on [Bjorn] and our entire community for himself and there's no coming back from that," Ludwig said. 

However, it seems like Rollo is not the only problem that Bjorn has to face when "Vikings" returns. Several speculations claim that Ragnar's other sons might try to take away his right to their father's throne. According to reports, it's possible that Ragnar's sons with his second wife Aslaug (Alyssa Sutherland) would plot against their eldest brother so they can take over their father's kingdom while he is still recuperating from the wounds that he incurred during the Paris raid. 

In other news, the companion novel for the show titled "The World of Vikings" is already available for pre-order. Fans of the series can soon get their hands on the book that covers its first three seasons, with further discussions about its historical facts and other behind-the-scene anecdotes. The book will be available starting Nov. 10 for only $34.99.

"Vikings" is set to return onscreen sometime in 2016.
