Yeah Ragnars wife is
but he is the one thats been trying to learn from Athelstan so maybe he just wanted the Monk to be apart of something that is normal to them. You said it freaked you out that he offered the Monk out of all ppl then seem to suggest his brother Rollo as an option. That would creep me out lol.
Its a very interesting series for sure, I barely watch TV so when I do watch something it must be great. And I'll take the 3somes over incest. Shows not over yet, wouldnt be surprised if there turns out to be incest in this series since I think it was prevalent back then.
