Ok I am still catching up, and I have to say that I agree with you guys, something is off the rails here.
I was horrified at the way they killed Ragnar off, just horrified. But...in true Viking form he handled that torture incredibly well. He never called out, cried or yelled. He kept his display of discomfort and pain to minimum to keep them from having the satisfaction. The whole thing made my stomach sick though. No more Ragnar??

Terrible.
Yes Ecbert seems to be losing his mind, he looked like a ghost in that scene where he is talking to Judith and his son. I am not done watching the episode where they land in that Muslim place but how WEIRD in the mosque!! In walks Floki, they take no notice, ok he was pretty quiet but then a band of wild, hairy, axe wielding strangers enter the place and cut the priests head off and not a single person shows a single bit of alarm???!!! They don’t even look up?? I mean really, that was a bit ridiculous. Are we to believe they are in such a religious trance that they did not notice the dude was beheaded?? I don’t think that prayers in the Muslim tradition render them totally deaf, blind and dumb. So that was really silly.
I also agree that Floki must not understand that these people worship one god, and not many. He hated that about the Christians. I’m not done watching but I gather from your posts above that Helga brings that little girl back. I also thought it was odd for Helga to have gone with them and for her to be unarmed, untrained to fight, but just waltzing around the battle scene as if she is on vacation. That was weird.
It’s all weird, and Lagertha seems to be finally allowing herself to feel how much she loved Ragnar and how sad she is about them breaking up. Maybe while he was gone she realized how much she missed and loved him. I dunno. Gotta finish tat episode but I am not as riveted by the show any more. It’s a little boring and the damn commercials on the History Channel are a drag. Every 6 minutes there is a commercial break and the commercials are as long as the segments of the show so it takes twice as long to get through and episode.
NOT HAPPY!!
