In addition to his hot-temper and unresolved envy, Rollo was infamous for his stubborn personality and never managed to make up with Ragnar.
Screen Rant added: “Rollo was jealous of the attention his younger brother got, and as he didn’t have much control over his emotions, this jealousy and hatred blinded him and drove him to betray his brother a couple of times.
“This, of course, led to fights between Rollo and Ragnar who never got to talk and solve their differences, with Rollo being incapable of apologizing properly.”
Rollo may still never get the chance to reconcile with his brother, but he could still cause more trouble if Clive Standen makes an unexpected appearance in season six.
Vikings season six will return in 2020 on the History Channel and Amazon Prime Video.
