'Vikings' season 3 spoilers: King Ragnar faces new threats; could son Bjorn withdraw himself from the king's camp?

History Channel's "Vikings" has been very successful so far. Season 3 is about to air in a month's time and fans cannot wait for another possible standoff between King Ragnar and a new enemy, plus, of course, the long-awaited reunion of Ragnar and Legartha. 

Season 3 may have the makings of the best season yet. While the previous seasons were more focused on Ragnar versus Horik, this time, the focus will be on how Ragnar will go about ruling Denmark as the king. 

In the season 2 finale, it was seen that Ragnar finally killed the Norse ruler Horik. Ragnar and Bjorn took Horik's sword and Ragnar is now King of Denmark. However, he might've made a huge mistake when he decided to spare the life of Horik's son Erlender, who could be the next villain. 

There's very little spoilers for season 3 despite it airing soon, but the most important ones were revealed by show creator Michael Hirst.

In an interview with Zap2it, Hirst shared, "We're going back to Wessex because I really like King Ecbert and Kwenthrith. Ragnar and him [Ecbert] are kind of equal. They can talk to each other, understand each other." 

Zap2it reported that this reveal leads to the raid in Paris, which will be the biggest adventure the show will take on. This adventure will include fighting Emperor Charles of France and Princess Gisla. But with such a huge story, season 3 might not be enough for it. 

"This isn't a storyline that's going to go away in a couple episodes. It's a storyline that's going right through the end of Season 3, into Season 4, and it has huge impact on several of our leading characters," Hirst revealed.

Clive Standen (Rollo) did mention at the Comic Con panel that someone important will die.

Meanwhile, Yahoo! spoilers introduced the idea that relationships in season 3 will undergo tests, particularly that of Ragnar and Bjorn. As Bjorn grows closer to Uncle Rollo, he might decide to get away from his father's leadership. 

"Our leads start in a bad place. They're in dysfunctional relationships of one kind or another and there's a lot of resolving to do," Hirst told Yahoo! News. 

"Vikings" season 3 will premiere on Feb. 19. In the meantime, fans can look ahead to season 3 with some photos from the cast here and the preview for the season here.
