Out of all the Comic-Con trailers that dropped last week, you may have missed one of the most exciting ones yet.

History released a new trailer for the second half of Vikings fourth season, and it looks incredible.

As you may remember (or not if you don’t watch the show), the first half of the season featured Ragnar and his Viking warriors suffering defeat at the hands of his brother Rollo and his Frankish forces. Consequently, Ragnar exiled himself from Kattegat and left his sons to grow up without him.

When he returned at the half season finale, basically, shit went down. He challenged his sons to kill him if they wanted to take his place as king – and we were left with the chilling cliffhanger of which one of them would.
