Vikings season 3

Many questions are left after the Vikings season two finale scandalous cliffhangers. Horik has been betrayed by his potential ally, all his plans were ruined and eventually he had been killed by the people from the Lothbrok clan. Floki has proven his loyalty to Ragnar who now will have all the power over Denmark and will become the newest leader. But we all know that no power comes without any consequences and Ragnar also knows it. Looks like Ragnar is going to reveal that he actually never asked the gods for the power he has gained now. So what will he do now as the king? Another important question is about Horik’s son - will he seek the vengeance?
