This series is amazing. They've strayed from the actual timeline to put the pizazz that you don't know what could happen. Floki's new threads intrigue me... I would think Ragnar rewarded him greatly for his loyalty. They might not always see eye to eye, but Floki has been there for him through thick and thin. If it wasn't for Floki, Ragnar would have died long ago. he owes more to him than his own flesh and blood. Aslaug's grief probably has to do with Ragnar and Lagertha spending more time together than they do during raiding season. I still suspect he will dump her off for Lagertha if she would take him back... however they would be more of a power couple that spend time away from each other tending to their obligations. Obviously Lagertha would have much to gain for her own people by courting the King. Both of their love is still there, anything is possible.
Season 1 debuted in March, Season 2 in Feb... I'm thinking this will start either after or during The Walking Dead's post mid-season finale of Season 5. 2015 is far away, but I'd rather have it start after TWD Season 5 is over so I still have something to watch.
