‘Vikings’ Season 4 Spoilers: Episode 3 Synopsis Released; What Will Happen In ‘Mercy’? [VIDEO]

It’s the episode we’ve all been waiting for! During episode 3 of the History Channel series “Vikings,” audiences will watch as Bjorn (Alexander Ludwig) faces off against a ferocious a bear. But will the Northman live to tell the tale of his battle against a fearsome beast?

When Season 4 of the epic, historical drama kicked off, the son of Ragnar Lothbrok (Travis Fimmel) ventured out into the wilderness to prove to his father that he could survive on his own. But little does Bjorn know that the bear won’t be the only danger lurking in the woods. According to the synopsis for the upcoming installment, titled “Mercy,” Erlendur (Edvic Endre) and Kalf (Ben Robson) will send a deadly threat Bjorn’s way in episode 3, proving that the creature will be the least of Bjorn’s problems.

“However you do it — kill Bjorn Ironside,” Erlendur comands a burley man in the promo video for the forthcoming installment. This proves that Kalf’s alliance with Lagertha (Katheryn Winnick) isn’t what is seems. When Kalf revealed he would share earlship with Lagertha, we theorized the power-hungry newcomer had ulterior motives — and it looks like they are to take down the Lothbrok clan … one son at a time.

Meanwhile, in Kattegat, Ragnar “sees that Floki (Gustaf Skarsgård) faces devastating punishment for the murder of Athelstan (George Blagden)." That punishment involves water torture — a form of torment Floki previously spoke of in the “Vikings” saga. But as Floki endures his punishment, a “mysterious visitor” will appear and urge Ragnar to be merciful.

Could the mysterious wanderer be Habard (Kevin Durand)? It seems very likely considering Durand dished to Zap2It at the 2015 San Diego Comic Con that the bearded nomad, thought to be the God Odin, would be making his way back to Kattegat in Season 4. According to Duran, Habard will “create more chaos” with his reprisal — especially between Ragnar and Queen Aslaug (Jessica Sutherland), who was intimate with his character in Season 3.

“Vikings” will air Season 4, episode 3 on Thursday, March 3 at 10 p.m. EST on the History Channel.
