The Season 3 ended with Ragnar collecting his guts to disclose to his good friend Floki that he was the culprit behind Athelstan's killing.
The last season also saw the Vikings returning from their disparaging attack against Paris except for Rollo who was left to marry Emperor Charles' daughter with the anticipation of obtaining favors from the aggressive outsiders.
However, due to Ragnar's poor health, people are starting to doubt on the kingdom's fate and fans can expect for a lot of political maneuverings in this new series.
According to GameNGuide, upon hearing the prophecy that a woman will soon rule Kattegat, Queen Aslaug devises a plan to successfully acquire the power by using Yidu, the character who shall play her slave.
Ragnar gets addicted with the medicine Yidu gives him, which deteriorates his health even before leaving for Paris.
But before the coming of Ragnar's demise, Lagertha, the former wife, will do everything to stop Aslaug from getting the power.
Fans will then expect for Lagertha and Aslaug to go head to head in the Episode 11 of Vikings Season 4 as likewise mentioned in Den of Geek.
Nonetheless, there have been speculations that before his death, Ragnar will confront Aslaug as he discovers that she is manipulating him in her mean desire of ruling Kattegat.
Rumors also suggest that Aslaug's plan will be thwarted by Ragnar himself as she prompts him to kill her. Further, Aslaug will be killed even before her possible encounter with Lagertha. Some also speculate that Aslaug will be killed during the two women's battle with Ragnar killing Aslaug.
So will fans expect for a Queen Lagertha after Ragnar dies? What will happen to the whole kingdom of Kattegat? Fans will have to wait until Vikings Season 4 finally returns by fall.
