Vikings' Ragnar and Floki we're once thick as thieves. Now, even saving each other's lives isn't even enough to thaw their icy friendship.

Ragnar (Travis Fimmel) saved the boat builder from agonizing torture in the wake of Athelstan's death, and, in "The Profit and the Loss," the beleaguered king pulled his old confidant from another watery grave. Despite this, the former friends will continue to feud as season 4 wears on.

 "It's very complicated. Very complicated," Gustav Skarsgård (Floki) said following the end of Floki's punishment, according to TV Insider. "It's almost masochistic in the sense that he still longs for Ragnar's love, and he always will, but he also resents Ragnar for having put him through the shame and the pain of the punishment. I think a part of him is just like, 'Why didn't he just kill me?'"

Now, Floki is intent on gaining back Ragnar's favor. Considering he thinks he did Ragnar a favor by "saving" him from the ills of Christianity, Skarsgård's character still believes he's in the right

"When we first pick up with him, he's very lost. He doesn't know where he's going. I never understood why he stuck around in Kattegat anyway and didn't just take off, but I think there's that weird longing that he still wants Ragnar's love back," the actor explained. "As much as he resents him, and as complicated as it is, he still longs to get back to that love and that relationship they once had."

Do you think the recent raid on Paris will bring Ragnar and Floki back together, or will his failure on the Seine leave the laconic warrior even more closed off than usual? Sound off in the comments below!
