According to the media outlet, Princess Aslaug will have more reason to worry about Lagertha when the shieldmaiden shows up at "Vikings" Season 4 midseason. Despite insecurities, however, Princess Aslaug will assert herself so that "Vikings" Season 4 will find her and Lagertha in major conflict.

Katheryn Winnick promises that Lagertha will surprise both "Vikings" series viewers and Princess Aslaug. Still, Lagertha and Princess Aslaug will not be the only ones battling for power when "Vikings" Season 4 returns.

Ragnar Lothbrok will also find that once trusted friend Floki may have taken his place with Bjorn Ironside. Parent Herald reports that as Floki and Bjorn Ironside grow closer, so might Ragnar Lothbrok find his relationship with his firstborn deteriorate at "Vikings" Season 4 midseason.

Perhaps to the exclusion of Ragnar Lothbrok, Floki and Bjorn Ironside will become fast friends in "Vikings" Season 4, as Entertainment Weekly cites revelation by Alexander Ludwig. An unsurprising development given the status of Ragnar Lothbrok as fallen, broken man at "Vikings" Season 4 midseason finale.

To be sure Lagertha, Princess Aslaug, Ragnar Lothbrok, Floki and Bjorn Ironside will make sure that "Vikings" Season 4 is anything but dull. As History releases the "Vikings" Season 4 midseason air date for September, fans can expect more tease on Ragnar Lothbrok, Lagertha and the rest of the stars.

Who do you think will win between Lagertha and Princess Aslaug in a "Vikings" Season 4 midseason showdown? Will Ragnar Lothbrok lose Bjorn Ironside to Floki for good as "Vikings" Season 4 midseason premiere opens?
