He was hallucinating before he was captured with the bible Floki gave him. I think the mass scene was excellent. He was seeing how similar the rituals between the vikings and Christians were and rejected the bread. The hallucinations is his inner conflict.
Did I miss something? What was Aslaug's prophecy on baring another son? Could it be that she dies in child birth? The seer is definitely one of my favorite characters, as little screen time that he gets. Jarl Borg, Ragnar, and Earl Harleson respected him despite if they disliked what he had to say. Telling Ragnar it was not his choice to make will probably mean one of them dies.
This leads me to Jarl Borg. By the preview for next week, it seems that his new wife has died, holding her skull and asking it questions means he has lost his marbles completely. He already isn't trustworthy, but now he is completely unstable. I think he will end up killing Aslaug as some kind of vengeance later down the road while she bares another son for Ragnar... after all Jarl Borg's wife was pregnant when he left her.
Horik is a buffoon. He seems to be a terrible king. Ragnar ran things until he had to leave Wessex, and now he wants to use Jarl Borg again after fighting with him, making a pact, and then turning his back on him? I'd have to side with Jarl Borg on this one. If I were him, I'd be telling them to f*** off.
I love Ecbert's character so far. Asking Athelstan about what should be done with the woman accused of being unfaithful was telling about his character. Christian law was absurdly oppressive to women during this time, and I think Ecbert can see how bullshit that is. Athelstan learned a lot of viking culture while he was with Ragnar, and I think the fact that Ragnar acknowledged him as a free man left that impression on him which leads to his conflict with Christianity. Horik is going to want vengeance on Ecbert, but I think Ragnar is going to want to reenter what ever deal Ecbert had in mind.... which will probably be attacking Aelle for more territory.
