Episode 16 of "Vikings" season 4 is quite interesting in many ways, primarily because this is the first episode in which the series is without their main character, Ragnar Lothbrok (Travis Fimmel).
Though there are a lot of fans still reeling from the death of Ragnar in the previous episode, the season has slowly built up the other characters to the point in which their storylines have fans interested on how they will move on without Ragnar.
Lagertha (Katheryn Winnick) has managed to reclaim her throne, but it seems like the new Queen is immediately faced with a confrontation as Ivar (Alex Høgh) crawled to the front of the hall to challenge her for the death of his mother.
Lagertha does not want to kill Ragnar's sons even though they have threatened her life ever since she took the throne and killed their mother, Aslaug (Alyssa Sutherland). This still seems to hold true especially after the prediction from the Seer claiming that one of Ragnar's son will kill her, making Lagertha's decision to still keep them alive very interesting.
"Crossings" also gave fans a glimpse of Bjorn's (Alexander Ludwig) plight as he and his crew are seemingly lost in the middle of the sea, with no land in sight. It doesn't help that Halfdan (Jasper Pääkkönen) and Harald (Peter Franzén) are questioning Bjorn's leadership.
Floki's (Gustaf Skarsgård) storyline was also a point of interest in the episode. After Bjorn and his crew landed in Spain, Floki seemed to have been struck strongly at the sight of the Muslim worshippers in the mosque. He then takes a stand, stopping Harald from killing all the men in the mosque.
Episode 17 of "Vikings" season 4 is titled "The Great Army," and although History has yet to release a synopsis for the next episode, it doesn't take a rocket scientist to figure out that the army that the three brothers are planning to gather is the "Great Heathen Army."
The promo also showed the three brothers — Ivar, Ubbe (Jordan Patrick Smith), and Sigurd (David Lindström) — discussing their plan to build an army that is twice the size of the one their that father was able to create.
Judith (Jennie Jacques) seems to know that the Vikings will not take the death of their King lying down as she warned King Aelle (Ivan Kaye) about the vengeance that the Vikings must surely be planning.
"Vikings" airs every Wednesday, with episode 17 scheduled to air on Jan. 11 at 9 p.m. ET on History.
