Who's gonna get killed on "Vikings" Season 4 as the historical series comes back for its second half? Fans can't help but theorize. Reports says that the main character, Ragnar Lothbrok (Travis Fimmel), the King himself is one of the many listed on the deathlist.

Quite a number of characters were killed on the first half of "Vikings" Season 4 as reported by Game Guide including; Queen Kwenthrith of Mercia (Amy Bailey); Earl Kalf (Ben Robson); Erlendur, son of King Horik (Edvin Endre); Yidu, Queen Aslaug's new slave (Dianne Doan); Angrboda, Floki and Helga's daughter (Rosalie Connerty) and Siggy (Jessalyn Gilsig)

Now rumors  reported that Ragnar will be killed off by one of his allies. There are still no reports on who will kill him but there are a number of suspects. Ragnar was gone from Kattegat for too long that even his sons hated him and even bowed to kill him. If he gets killed, one of them will be the king

But before his rumored death, the episodes will focus on the reason why Ragnar came back instead of what he did when he was away, cited Parent Herald.

A new female character, Astrid (Josefin Asplund) will be joining the cast as Lagertha's (Katheryn Winnick) lover. A dramatic face-off between Lagertha and Queen Aslaug is also to be expected

"It's going to be a cat fight. The two power women go head to head," Winnick said in an interview with Entertainment Weekly "It's a really interesting scene because you don't expect what happens."

On the lighter side, Bjorn (Alexander Ludwig) is travelling to Mediterranean with Floki. "They work on their tans a little bit," Ludwig said on the same interview. "You're definitely going to see Floki and Bjorn's relationship flourish,"  he added.
