'Vikings' Season 4 Midseason Air Date, News & Update: Ragnar Lothbrok's Fate Is Sealed In Heartbreaking S4? Ivar More Dangerous Traitor Than Rollo?

"Vikings Season 4" midseason premiere, which airs this fall, brings "Warcraft" star Travis Fimmel as Ragnar Lothbrok back to power in Kattegat. Ragnar Lothbrok, Bjorn Ironside (Alexander Ludwig) and Sigurd Snake-In-The-Eye will find out in "Vikings Season 4" that Ivar The Boneless (Alex Høgh Andersen) is far more dangerous than traitorous Rollo (Clive Standen).

According to TV Guide, "Vikings Season 4" midseason premiere resumes the six-year time jump where Ragnar Lothbrok meets his grown sons in Kattegat. Last seen at the "Vikings Season 4" midseason finale was Ragnar Lothbrok issuing a challenge to Bjorn Ironside, Ubbe (Jordan Patrick Smith), Hvitserk (Marco Islø), Sigurd Snake-In-The-Eye (David Lindstron) and Ivar for Kattegat rule.

While Ragnar Lothbrok assumed a taunting tone to his sons, "Vikings Season 4" will prove that Bjorn, Ubbe, Hvitserk, Sigurd and Ivar are not to be messed with. Michael Hirst assures via TV Guide that Ragnar Lothbrok will prove his strength as a ruler in "Vikings Season 4."

Michael Hirst also teased that the "Vikings Season 4" continuation will be such that fans will be glad Rollo did not kill Ragnar Lothbrok. As "Vikings Season 4" reunites Ragnar Lothbrok with his sons in Kattegat, Michael Hirst further teases that Ragnar Lothbrok will meet an unbelievable fate.

Michael Hirst tells TV Guide that Ragnar Lothbrok will make History fans cry buckets in "Vikings Season 4." In the meantime, Ragnar Lothbrok would need to watch out for Ivar The Boneless as the "Vikings" series progresses.

Perhaps what makes Ivar The Boneless more dangerous for Ragnar Lothbrok or anyone who stands in his way is the charm that "Vikings" fans see him exude. IGN cites the actors playing Ubbe, Hvitserk and Sigurd Snake-In-The-Eye in predicting that Ivar The Boneless will be a "Vikings" series favorite.

The wait seems interminable for Ragnar Lothbrok, Bjorn Ironside, Ubbe, Hvitserk, Sigurd Snake-In-The-Eye and Ivar The Boneless to return for the "Vikings Season 4" midseason premiere. Parent Herald previously cited a July "Vikings Season 4" midseason premiere air date while History teases on Twitter that Ragnar Lothbrok will soon return.
