There is little doubt that there will be plenty of deaths in "Vikings" Season 5. Fans already have theories about the casualties when the show returns to History this fall. But is it possible that Floki will be the first to die in the fifth season?

People have been expecting to see Ragnar Lothbrok's best friend take a different path after the death of his beloved Helga. Some believe that Floki might even convert to a new religion now that he feels like the gods have turned against him. However, it looks like the future is bleak for the carpenter now that Gustaf Skarsgard will be joining a different hit series.

Gustaf Skarsgard joins 'Westworld' Season 2

Deadline has recently reported that Gustaf Skarsgard has been cast in "Westworld" Season 2. The star of "The Way Back" will portray Karl Strand in the HBO series. Although not much is known about the character, the report states that he is "a white-collar guy comfortable in the field." It is possible that this means Karl has no problem dealing with robots in the sci-fi western.

Interestingly, Skarsgard has been revealed to be one of the new series regulars in "Westworld" Season 2. Fans were immediately concerned about the news since this might mean the actor might no longer be able to commit to "Vikings."

Is Gustaf Skarsgard leaving 'Vikings'?

Naturally, people are wondering whether Skarsgard will no longer be able to work with the History series after "Vikings" Season 5.

Some believe this possibly means his character will be killed off from the show to make way for his new project, which would require him to work away from the History show's usual filming locations.

Neither Skarsgard nor History have commented on the speculations about his possible departure. Hopefully, Floki will stay alive in the show and become a recurring character instead since he is one of the most intriguing people in the series.

Who will die in 'Vikings' Season 5?

Floki is not the only one who could get written off the series. There are speculations that Lagertha will also be killed by one of Ragnar Lothbrok's sons. Although it seems obvious that Ivar the Boneless will be the one who will murder the Queen of Kattegat, some believe that she will be assassinated by Ubbe so he can rule his father's kingdom.

It is still unclear whether Gustaf Skarsgard's new role in "Westworld" Season 2 will lead to Floki's death in the History show. In the meantime, "Vikings" Season 5 is set to premiere on November 29.
