I should think that this show is the first some of us have heard of Ragnar, though. I, for one, know very little of the historical Vikings and Sagas and so forth. Therefore, spoilers.
Discussing details of episodes that have preaired or confirmed
details of future episodes are spoilers. Discussing mythology and historical facts most definitely isn't
. Neither is speculating things based upon already aired episodes. Learning something new isn't a synonym for being spoiled, FFS.
I swear, people throw that damn word around way too much.
