Vikings: 9 Most Shocking Moments So Far
2. Aslaug Arrives In Kattegat
In season 1, Ragnar meets the princess Aslaug and is eventually enticed to sleep with her on more than one occasion. This was, of course, all while he was still married to Lagertha, but this was not the part that shocked fans. That said, we were still somewhat surprised that someone could betray Lagertha like that.
No, the real shock came at the start of season 2. We all thought that Aslaug was just a one-time thing and we would never see her again and yet she shows up unannounced to Kattegat while pregnant with Ragnar's son and she does not even try to keep it a secret. This eventually leads to some very uncomfortable dinner conversations and Lagertha deciding to leave Kattegat with Bjorn.
At the start of the show, no one ever expected to see someone other than Lagertha ruling besides Ragnar.
