After the shocking events of the last "Vikings" episode, "Blood Eagle," the time has come for Ragnar, Lagertha and King Horik to forge west, seeking vengeance against King Ecbert.

That's exactly what will happen in Thursday's (April 17) episode, "Boneless," though there is an internal struggle going on within the Vikings. Ragnar still views himself as the smartest of the group and makes decisions without consulting others, including King Horik. Of course, that's not the way things are done, and Horik has no problem reminding Ragnar that the two of them are not equals. The first clip below gives a preview of their confrontation. Will Ragnar fall in line?

In the second video, Athelstan meets Princess Kwenthrith. While initially she is interested in his time with the Pagan vikings, the princess quickly loses interest after seeing how unwilling he is to discuss it. What she doesn't realize is Athelstan is still haunted by those visions of his.

"Vikings" airs Thursday at 10 p.m. ET on History.
