The tensions in Kattegatt are boiling over in Wednesday's episode of Vikings. In this exclusive sneak peek, Hvitserk (Marco Ilsø) confronts his brother Ivar (Alex Høgh) over Margrethe's (Ida Marie Nielsen) death and Ivar has the gall to deny ordering Margrethe's killing. Hvitserk sees right through this and calls out the King — in front of everyone — for why he wanted Margrethe dead.

"Because she knew you could never get a woman pregnant!" he proclaims.

It's at that moment that Ivar decides to make a game-changing announcement: Freydis is pregnant with his child. Well, at least Ivar thinks it's with his child.

Hvitserk is not excited at the prospect of getting a new niece or nephew, though, and Ivar warns him to watch his mouth. "Why, will you kill me next?" Hvitserk asks.

And to be honest, maybe. Ivar already killed one of his brothers, and we doubt he'd hesitate to do it again.

Vikings airs Wednesdays at 9/8c on History.
