Vikings is a popular historical drama series airing on History and Amazon Prime, and the series is taking a mid-season break. In the first half of season 6, fans saw the Rus leader Oleg (played by Danila Kozlovsky) lead an invasion on Scandinavia with Ivar the Boneless (Alex Høgh Andersen). Fans are wondering whether Oleg and his second wife Katia (Alicia Agneson) will turn on Ivar and kill him in the second half of the season.
Fans of Vikings were introduced to Oleg and Katia in the first half of season 6 after the Rus leader was visited by Ivar the Boneless.
Oleg of Novgorod is the Grand Prince of Rus and he was responsible for killing and torturing his own brothers to stay in power.
He initiated a plan to invade Scandinavia and convert the Vikings to a Christian faith and he convinced Ivar to join him to get revenge on his family.
Fans were also introduced to Oleg's second wife, Katia, who is played by the same actress who played Ivar's wife Freydis.
Viewers believe Katia is a reincarnation of Freydis, as Ivar murdered Freydis by strangling her. They believe Katia and Oleg may be working together to kill Ivar.

There are many reasons to believe Katia would want to get her revenge on Ivar, as he killed Freydis after she showed so much faith in him.
She was the one who encouraged him to believe he was favoured by the gods, and his new-found self-confidence was a result of her encouragement.
Before Freydis was killed she told Ivar she had a similar name to the goddess Freya - the goddess of love - so she may possess special powers of seduction.
If Freydis did really reincarnate into Katia in season six, she could be using her powers to seduce Ivar once more, luring him into a false sense of security.
She could also be using Oleg as a distraction so Ivar will not suspect her motives, believing Katia is only trying to support her husband Oleg in battle.
