Ivar really used the blood eagle during his time of leadership. He was thought of as one of the Viking's greatest leaders. I have been waiting since the show started for his birth. It is still unknown the real reason why the term boneless was used for him. I was curious to know how the show was going to portray him and his condition. Good job on their part.
Loved the episode. The only thing I found odd was Ziggy/Horik conversation. I'm like 99% sure she mentioned Ragnar's weakness to Horik in a previous episode.
