Vikings: 9 Most Shocking Moments So Far

3. Ivar Kills Sigurd

Let’s get straight to the point, no one - and I mean absolutely no one - expected Ivar to throw his axe at Sigurd across a table while feasting.

This moment comes at the end of season 4 part 2 after the sons of Ragnar have exacted revenge for the death of Ragnar and think they have claimed their land. During a feast of celebration, the brothers are deciding on what to do with the Great Heathen Army and of course Sigurd and Ivar begin to bicker, as brothers do. But Sigurd crosses a line mocking how Ivar cannot perform with a woman and that he should cry to his dead mommy. And against Ubbe's advice to relax, Ivar's response is to throw his axe.

Now this wasn’t just a shock to us but to the army as well. It was truly a perfect blend of surprise, betrayal, and show of how ruthless Ivar is. Not only that, but the fact that one of the sons of Ragnar could be killed in such a way was mind boggling.
