It’s almost 2015! And you know what that means, right? “Vikings” is one step closer to airing it’s highly anticipated Season 3. But before the History Channel series unveils its premiere episode on Thursday, Feb. 19, the historical drama has made sure to keep their fans on the edges of their seats with the release of action-packed promo videos.

The most recent trailer gave fans an in depth look at the upcoming season -- despite the video only lasting 18 seconds long. Below we’ve listed everything we’ve learned about the new season of “Vikings” straight from the teasing trailer:

1. Attack On Paris

In the promo video someone shouts, “Tomorrow we attack Paris.”

Michael Hirst, showrunner of the bloody series, revealed that the Parisian storyline wouldn’t be a plot that concludes in a few episodes. “It’s a storyline that’s going right through the end of Season 3, into Season 4, and it has a huge impact on several of our leading characters,” Hirst teased during a group interview at San Diego Comic-Con.

2. Lagertha (Kathryn Winnick) Gets Betrayed

The Earl calls out a character in the Season 3 promo video for their disloyalty. But who could Lagertha be referring to? We're suspicious of the show’s newest character Kalf (Ben Robson), who will portray a character that’s second-in-command to the shield maiden.

TVLine revealed that Lagertha will underestimate Kalf’s leadership ability when he quickly makes a name for himself in Kattegat. Could Kalf be trying to steal Lagertha’s title?

3. Father/Son Issues

From the promo video it looks as though fans can anticipate some issues between Ragnar (Travis Fimmel) and Bjorn (Alexander Ludwig) to rise. “You do not leave me,” Ragnar shouts at his son, followed by a slap across the face.

Could Ragnar’s jealousy be getting the best of him? Sure, he’s the most powerful man in Denmark. But in a few years his younger and soon-to-be-stronger son will be stealing the spotlight – and we’re sure that’s eating away at Ragnar.

"Bjorn went on to do some incredible things, arguably more than his father. And you know, the story's just begun because what Ragnar's son did was magnificent," Ludwig teased during an interview with TV Guide.

4. Princess Kwenthrith (Amy Bailey) Is Back!

The sassy princess who we all love to watch will be back with her outspoken ways when Season 3 returns.

“We’re going back to Wessex because I really like King Ecbert (Linus Roache) and Kwenthrith,” Hirst told Zap2it during an interview. When fans last saw the princess, she was sizing up the Vikings-turned-mercenaries, seeking one that she could produce “giants” with.

5. Marital Woes

The honeymoon stage is clearly over for Floki (Gustaf Skarsgard) and Helga (Maude Hirst). In the promo video, Floki grabs the mother of his child’s throat and screams at her, “You swear?”

6. Lots of Sex

When the Vikings aren’t fighting battles in Paris, they’ll be shacking up with one another. The promo video for the upcoming installment teased a lot of steamy scenes in Season 3. The only question now is will one of them involve Lagertha and Ragnar?

Winnick teased during a Gold Derby Google+ Hangout that fans shouldn’t totally cross off the idea of the former partners rekindling their love. “There is interest,” she revealed the chemistry between the two characters. “I think Lagertha is interested and I think Ragnar is also in the picture and I guess you’re going to have to wait and see!”

“Vikings” will return Thursday, Feb. 19, at 10 p.m. EST.
