ET has an exclusive first look at Wednesday's episode of Vikings, where Ivar (Alex Høgh Andersen), who was forced to deliver the news of the death of his father, Ragnar (Travis Fimmel), receives some news in return: Lagertha (Katheryn Winnick) has killed his mother, Aslaug (Alyssa Sutherland).
The discovery clearly doesn't sit well with the youngest of Ragnar's sons, who despite his handicap, decides to avenge his mother's death.
"Welcome, Ivar," Lagertha, the new queen, calmly states in the clip.
"I've come here for justice. Everyone knows that you killed my mother for no reason except ambition, therefore I demand justice," Ivar angrily replies, pushing away his brother Ubbe's (Jordan Patrick Smith) attempt to restrain him.
"Perhaps he understands some things that you don't," Lagertha says.
"I understand everything perfectly!" Ivar yells back. "You murdered my mother in cold blood. I want revenge. I challenge you to single combat!"
Watch the full scene above.
Vikings airs Wednesdays at 9 p.m. ET/PT on History Channel.
