'Vikings' Season 4 Midseason Air Date, News & Update: Ragnar Lothbrok Outshone By His Sons? Ivar The Boneless, Sigurd To Come To Blows?

"Vikings" Season 4 midseason premieres to the new highlight of "Warcraft" lead Travis Fimmel as Ragnar Lothbrok and his sons. Although legendary in his own right, "Vikings" Season 4 will see Ragnar Lothbrok overshadowed by sons Bjorn Ironside, Ubbe (Jordan Patrick Smith), Hvitserk (Marco Islø) with (promising enemies) Sigurd Snake-In-The-Eye and Ivar The Boneless.

As much as Ragnar Lothbrok with brother Rollo (Clive Standen) all the way to "Vikings" Season 4 midseason finale, the same may be mirrored among his own sons. "Vikings" Season 4 midseason may particularly reveal conflict between Sigurd Snake-In-The-Eye (David Lindstron) and Ivar The Boneless (Alex Høgh Andersen).

IGN reports that Princess Aslaug (Alyssa Sutherland) in events leading to "Vikings" Season 4 midseason finale contributed to the conflict between Sigurd Snake-In-The-Eye and Ivar The Boneless. Ragnar Lothbrok taking Rollo on that final challenge with Bjorn Ironside (Alexander Ludwig) and Lagertha (Katheryn Winnick) in Paris leaving Sigurd Snake-In-The-Eye behind will unveil bigger consequences as "Vikings" Season 4 continues.

Ragnar Lothbrok has obvious affection for Ivar The Boneless above his other sons as apparent at "Vikings" Season 4 midseason finale. This will continue to play out in "Vikings Season 4."

However, Ragnar Lothbrok and his actions in "Vikings Season 4" may only be the tip of the iceberg. In history, Sigurd Snake-In-The-Eye and Ivar The Boneless are the two Vikings who will later on be kings.

Their renown as Vikings will surpass Ragnar Lothbrok. Bjorn Ironside, Ubbe and Hvitserk will all be great men in Vikings history but not as much as Sigurd Snake-In-The-Eye and Ivar The Boneless.

History Extra cites "Vikings" series creator Michael Hirst in saying the name Ragnar Lothbrok is enough to open doors for his sons. However, as "Vikings" Season 4 midseason will reveal, Sigurd Snake-In-The-Eye and Ivar The Boneless seem to have little need for it.

To be sure, Ragnar Lothrbrok will come to know in "Vikings" Season 4 that Sigurd Snake-In-The-Eye and Ivar The Boneless are almost as different as night and day. Whereas Sigurd Snake-In-The-Eye has a strong moral compass, Ivar The Boneless has a dangerous slyness that Ragnar Lothbrok will recognize.

Ragnar Lothbrok will see if one among his sons will try to kill him as challenged in "Vikings" Season 4 midseason finale. History will air "Vikings" Season 4 midseason premiere on July 7.
