Vikings Season 4 Trailer: Ragnar is a Marked Man

Are you guys prepared for Vikings Season 4? I mean, really prepared?

I'm asking because I know how many of you have come to love and respect King Ragnar, and well, he's a marked man. He barely escaped Vikings Season 3 with his life, and now everyone wants to claim the throne he's claimed for themselves.

Auslaug believes she was born to lead the Vikings, and being the wife of the king is hardly the same thing as leading them herself.

Lagertha will be continuing her cold and calculating journey from shield maiden to powerful Viking warrior with her man Kalf. She still has an attachment to Ragnar, of course, but can that really stop her?

Sibling rivalry to the nth degree between Rollo and Ragnar hasn't stopped Rollo from remaining in France for the ultimate betrayal to both his brother and the Viking people. We know his future is solid and on the rise.

And in order for King Bjorn Ironside to take his rightful place, his father will have to perish. Do we expect him to go gently into the night? We sure hope not!

Finally, Floki lived, but don't expect him not to pay for what he did to Athelstan, as he'll be arrested, putting him at odds with the current king just like everyone else. 

There are some pretty tangled webs on Vikings, so we can expect some pretty epic battles to take place before our very eyes. So I repeat. Are you prepared?

Vikings returns Thursday, February 18 on History Channel!
