TV Equals: "Last night’s Vikings dealt its loyal fans a tough blow. In a moment of selflessness, Siggy died saving Aslaug’s sons from drowning. Losing a main character who has been present since the beginning of the show is rough. Siggy is such a complex, interesting character and had many more stories in her. Reportedly, Jessalyn Gilsig made the decision to leave the show because filming in Ireland was not feasible for her. There’s not much that can be said about that—if she needed to go, she needed to go. But it’s still a major loss for the fans."
