"Vikings" is back with a slow-paced, dialogue-laden episode which keeps things interesting even if it doesn't offer much novelty.
Ragnar is back and he wants to organize and expedition to get his 'other' son back (with the excuse of vengeance). But Bjorn wants to go with Floki to the Mediterranean. All the while, Ragnar's other sons are all grown up and are dealing with having Ragnar as a father.
The episode doesn't really progress much the story, but it reconnects the viewer with the plot and the characters in an engrossing way. Nothing is especially original, but the production, locations, acting and atmosphere continue being top-notch. The fan will enjoy it.
And with the show teasing us with two new campaigns in the near future, probably action-packed episodes are around the corner.
