Who’s ready to raid? “Vikings” will continue with its Season 3 storyline when episode 2 is shown on the History Channel Thursday, Feb. 26. And, according to the promo video for this installment, we have one warning for viewers: Hold on to your heads!

In the trailer for “The Wanderer,” audiences can see Ragnar (Travis Fimmel) and his Nordic warriors begin their journey to defeat the army of Princess Kwenthrith’s (Amy Bailey) treacherous brother. But their intimidation will start before they even step foot ashore. The Vikings will decorate their boats with the decapitated heads of slaughtered soldiers from the army of Kwenthrith’s deceased uncle. Talk about making an entrance.

But just how successful will the sword-wielding Vikings be? According to the trailer for the episode, one of Ragnar’s fighters might not make it out of the battle alive.

“How many more of us must die for your Christians?” Floki (Gustaf Skarsgard) asks Ragnar in distress.

Any guesses on who the fallen warrior could be? Well, considering Alexander Ludwig, who plays Bjorn on the series, teased that his character and Porunn (Gaia Weiss) would face a “very big obstacle,” we’re concerned Floki could be referring to the expecting couple.

“Unfortunately, things take a turn for the worst. Something very severe happens, and you’ll see how deep their relationship really goes,” Ludwig warned during a press conference. “It’ll be very interesting for the fans to see how willing they are to overcome it.”

Viewers will also be introduced to a new character in episode 2. Kevin Durand will make his “Vikings” debut as Harbard, the mysterious wanderer who will turn up in Kattegat, after a vision by Siggy (Jessalyn Gilsig), Helga (Maude Hirst) and Aslaug (Alyssa Sutherland). His arrival is clearly pivotal to the plot, given the installment is named after the mystical newcomer.

“Harbard’s actions will pretty much change the course of action for all of the other characters in that episode, and he leaves a pretty deep kind of a wound I guess -- a deep mark -- and I would say that that’s probably the one that probably has the most impact,” Durand said during a press interview.

“Vikings” Season 3, episode 2, “The Wanderer,” will be shown on the History Channel Thursday, Feb. 26, at 10 p.m. EST.
