Bloodshed and mayhem continue in Vikings season 3 as King Ragnar continues to help princess Kwenthrith regain control over the city of Mercia.

Earlier, the Norse ruler had beheaded the princess's uncle, and in the second episode of the blockbuster series, Kwenthrith was seen stabbing her uncle's head repeatedly.

She later revealed that her uncle and elder brother were sexually abusing her since she was just six years old.

In the third episode titled, Warrior's Fate, Ragnar will march with his troop of vikings to capture and defeat Kwenthrith's elder brother.

However, a promo released by History Channel reveals that the legendary Norse rule could bite the dust as his warriors would suffer massive causalities.

The promo also suggests that this will lead to difference of opinion between Ragnar and Floki.

"Here we are under an English sky burying our dead. This is your fault, Ragnar," Floki tells his longtime war partner.

"If you don't want to fight, then don't fight," the Norse ruler replies, which annoys his old friend.

Meanwhile, Bjorn does something wrong that prompts his father to tell him, "I can't even look at you..."

This seemingly has something to do with the ongoing war, which forces Bjorn to do something against his father's wish.

Bjorn's move could be related to the ongoing war between the Wessex and the Vikings, which forces him to go against Ragnar's wish.

The official synopsis of the upcoming episode reads:

"King Ecbert visits the developing Viking settlement as the first harvest is sown and rebuffs criticism from his leading nobles. In Mercia, the Wessex/Viking forces charge at the battle at the Hill of the Ash. In Kattegat, Harbard (Kevin Durand) arrives in to the Great Hall and his mysterious aura fascinates Aslaug (Alyssa Sutherland) and Helga (Maude Hirst) but Siggy (Jessalyn Gilsig) remains suspicious. There are strange and tragic happenings in Kattegat, and Siggy suspects Harbard is the cause."
