Vikings Finale: Donal Logue Previews Horik and Ragnar's Deadly Showdown

Joey doesn't share food, and King Horik (Donal Logue) doesn't share power.

After weeks of growing tension with Ragnar (Travis Fimmel), Horik is finally ready to betray his ally on Thursday's epic Vikings finale — and he won't be alone.

The penultimate episode ended with Ragnar's right-hand man Floki (Gustaf Skarsgard) seemingly eager to accept Horik's proposition, one that would not only take out the former farmer but also his children. And while it didn't take a Seer to see Horik's treachery coming, Floki's duplicity cuts deep. Though, we can't say we don't understand. Floki is, first and foremost, a devoutly spiritual man and Ragnar's growing tolerance of Christianity, combined with his mounting arrogance, provided an easy in for Horik with the ship-maker.

"I think that they are kindred spirits on a religious spiritual level," Donal Logue tells TVGuide.com. "They, more than anyone else in the world that we're exploring, are the most distrustful of Christianity and what they consider the pagan religions. So [Horik] plays upon that," Logue tells TVGuide.com.

But while Horik used the gods to win Floki's allegiance, Logue promises Horik's faith is more than a mere tactic. He just frames the gods' will to match his own, natch. "I think he really believes in what he believes, but I also think he really believes in power," Logue explains. "He's really completely addicted to the game of what it takes to be king and ... he saw [Ragnar] as someone who could help Horik expand his wealth, but then Ragnar became so famous in and of himself that then he became a threat."

Growing jealousy of Ragnar causes Horik to be driven by "fear and insecurity" in finale, Logue says (and we saw how well that worked out in the battle against Ecbert last week). But will Horik learn from his mistakes when it comes to this final battle? "Well, he's hatched this plan with [Floki] to create this new order ... but it doesn't play out exactly as he thinks," Logue teases, refusing to say whether or not these surprises bode well for the King.

While Horik believes his fate lies with the gods, it seems Ragnar's fate will be decided by those he put his trust in. Though Floki has apparently jumped ship, Siggy remains a wild card. And it looks like the social climber has finally achieved that power she's been after, because wherever Siggy throws her allegiance is easily game-changing. So who will she side with: Ragnar, the brother of Rollo, the man she's been taking care of and sleeping with, or Horik, the man she's been feeding information and sleeping with?

"She's this woman existing by her wits and whatever means necessary to kind of stay relevant in the game. And she's very aware when she tells Rollo, 'King Horik's important. He has the money. He has the armies.'" Logue says. "On the other hand, a line was crossed when Horik dehumanized her... so she probably has some ammunition and motivation for not liking her situation with him."

So while Siggy is off debating whether or not to help Horik kill Ragnar and all his children (whom she's helped to raise, lest you forget), what will the famed Earl be up to? Ragnar's spent much of this season on the sidelines, doing his best to toe the company line, and he will remain in the shadows throughout most of Thursday's episode. But that doesn't mean he's completely in the dark regarding Horik's agenda. "They both play big games in the finale," Logue teases. "I think Ragnar's also smart. He probably knows from the get-go."

No matter how the events of the finale play out, Logue says that he doesn't view Horik as a villain. "He's a human being in a position of power," Logue says. "To become king, he's had to do a lot of dirty stuff to be where he's at and he's had a lot of dirty things done to him, so he's become embittered and hardened because of that."

We have to admit, Logue has a point. We've seen all the Vikings do terrible, unforgivable things. But as the actor points out, "these were people living in brutal times," and it's not like Ragnar's been all sunshine and rainbows this season.
