Since Fimmel left Vikings, the show has progressed by focusing on the tale of Ragnar’s sons.
Vikings’ creator also felt like Ragnar’s story had gotten told to completion, which is why he does not really miss writing for the character.
In terms of his Vikings experience, Fimmel recently revealed that he didn’t have a hard time leaving the show, and he wasn’t the only one who was ready for his character to be retired.
