Vikings season 4: An incredible video for the next episodes!

A few days after the release of a new episode, History unveils an incredible promo video for the continuation of season 4 of Vikings!
It promises ! While we dévoilions the promotional video of episode 15 of season 4 of Vikings , the cable channel History offers us another trailer showing us what we can expect in future episodes. It begins with a heartbreaking moment between Ivar and Ragnar, where the father seems to give his son a cross that the young man will squeeze so hard, that he will open his hand. Then, the tagline tells us that one of our heroes will fall – not to show Rollo, Lagertha, Floki, Ubbe, Sigurd and Astrid – and that others will take on importance. Should we expect the death of one of these 6 characters? The last images concentrate on the Calvary of Ragnar in the hands of King Aelle, and we find that King Ecbert seems completely lost following his decision. The last words we read tells us: “The time of revenge has come.”
Another setting of this trailer exists and shows us essentially the same images involving Ragnar, King Aelle and King Ecbert. It would also appear that the Seer saw the torture of Ragnar, which could allow him to inform the characters in Kattegat, which could lead to a retort before it is too late. Could it be that Lagertha launched an offensive against King Aelle? We also see that the son of Athelstan, Alfred, will be present again and that we will live the continuation of the journey of Bjorn! Lately, we dévoilions you the synopsis and promotional photos from episode 15 of season 4 Vikings! What do you expect from the rest of the series?
