The bearded warriors return tonight as Vikings' fourth season continues with a double bill. In the first episode, Ragnar has headed back to Kattegat, where he devises a plan to return to Wessex to right past wrongs. While in the second episode, Bjorn prepares to fulfil his dream of exploring the Mediterranean, and Ragnar seeks to equip his voyage to Wessex, even while being warned that the gods have deserted him. He'll be needing those Gods too, we'd imagine.
