When Yidu handed the herb to Ragnar, it was wrapped in a leaf. As everyone knows, betel is a nut but often times, it is wrapped in the leaf of the Piper betel vine.
Executive producer Michael Hirst said that fans need not worry even if Season 4 shall mark the end for Ragnar Lothbrok as “Vikings” shall continue without him.
Hirst added that Season 4 of “Vikings” is to be its longest to date and will continue to run and run.
He explained that he has a huge hope that “Vikings” can continue beyond Ragnar as his sons, led by Bjorn Ironside, will continue to pick up the show’s story.
The showrunner said that he always anticipated continuing with Ragnar’s sons because many of them became as famous, if not more famous than their father.
Bjorn Ironside was also featured in episode 4 of “Vikings” and his life inside the frozen wilderness was showcased. He was fiercely battling against a grizzly bear before fighting Earl Kalf’s people just to be able to survive.
The fourth episode of “Vikings” also revealed a major fight between the Norse king and his second wife Aslaug, as she took her son away from him while saying that Ragnar will not be able to make his son be like him.
