'Vikings': Why Hvitserk, son of Ragnar Lothbrok, deserves his own storyline
So far, we have only seen Hvitserk alongside his brothers, but a time may come soon where his darkness overshadows that of Ivar, as cited by the creator himself
Rollo was always overshadowed by his brother Ragnar Lothbrok, the protagonist of 'Vikings', till the time of his death in season 4. Now that Ragnar's many sons are the protagonists in season 5, it is evident that Hvitserk is a kind of a 'Rollo' compared to all his brother - Bjorn Ironside, Ubbe and Ivar the Boneless.
Starting right from season 2, where Hvitserk was introduced, until now in season 5, he has been seen only alongside his brothers, especially Ubbe and now Ivar. At the beginning of season 5, he left Ubbe's side to join his rather evil brother. By the time we have sailed to the current episode, Ivar has already humiliated Hvitserk and even teased him to be sacrificed.
