Yes, and I add something more:
If this people look in Wikipedia they will see that Ragnar dies in Northumbria killed by being thrown into a pit of snakes.And it happens when their childrens are adults. So everybody can keep calm.

God people, don't you have wikipedia? Put Ragnar Lodbrock and see the history, Ragnar won't die know.

Stop arguing, Ragnar won't die. Vikings follows the history, and Ragnar dies in Northrumbia, but this when their childrens are adults.
