Another big question that fans want answered involves Swedish star Alicia Agneson, who has played two different characters on Vikings. In season 5, Ivar married Agneson's Freydis, a former slave that he freed and later killed after learning of her betrayal. Freydis helped Bjorn take Kattegat from Ivar, who fled to Russia in the first part of season 6. It's here that he meets Katia, the spitting image of his dead ex and the fiancée of violent Rus Viking Prince Oleg. In fact, the raven-haired princess is also portrayed by Agneson, so what gives? According to the actor, there was "quite a big spoiler" in the first part of season 6.
"In the last episode where Victor joins [the group] in Russia... he can't see the likeness [between Freydis and Katia], it's only Ivar," Agneson told Metro. The same thing happened when Ivar asked Hvitserk if he saw a similarity between Katia and Freydis, so it does seem as though it's all in Ivar's head. "I suppose you don't really know yet... but it's in the eye of the beholder," Agneson teased. "We'll see what happens and if [Katia] does know something about Freydis."
What does Alex Høgh Andersen make of this theory? "I don't know, but it's interesting to think about," he told TV Guide. "We have seen scenes of Katia though where she is looking like we always see her where Ivar's not in the scene, so that's some food for thought."
