"Vikings" season 3 ended on a strange cliffhanger. Ragnar Lothbrok (Travis Fimmel) successfully raided Paris but was wounded to near-death, and Rollo (Clive Standen) was left behind. The latter was then offered to marry Emperor Charles' daughter, Princess Gisla, and would be given land and the title of "Duke" as well. 

According to a report from the Venture Capital Post, season 4 is going to focus very heavily on the decisions and conflict between Ragnar and Rollo. The latter already betrayed his brother before, but the report states that things will be different in season 4, particularly because of Rollo's change in status and beliefs. 

The report recalls what the Seer prophesized to Rollo when he stated, "If you could see what I can see when you reach Paris, you would be dancing naked in the sand." 

According to the report, Fimmel stated that Rollo wants to prove that his new power, title, and marriage is the reason why he should be happy and "dancing naked in the sand." The actor also said that this will cause a higher level of conflict that will lead to a different set of ramifications as well. 

It's been long speculated by fans that Ragnar may see his end in season 4 but it may not be at the hands of Rollo. As the report from VCPost points out, historians and folklore experts know that Ragnar Lothbrok, at least according to Viking mythology, died at the hands of King Aella in Northumbria and not during a conflict with France and his brother Rollo. 

If Ragnar does die in season 4, then the series will focus on his sons, particularly Bjorn (Alexander Ludwig). An older report from the IBTimes cites series creator Michael Hirst and his enthusiasm to focus on Bjorn and the other children of Ragnar Lothbrok before the series ends. 

"Vikings" season 4 is set to premiere in early 2016.
