"The Originals" Season 4 will awaken unhappy Mikaelsons, who will have a couple of reasons to feud despite efforts by Hayley Marshall (Phoebe Tonkin) on their behalf. Klaus Mikaelson (Joseph Morgan) and siblings Elijah (Daniel Gillies), Kol (Nathaniel Buzolic), Freya (Riley Voelkel), each trapped by "The Originals" Season 3 finale may not have learnt their lessons by S4.
In an interview by Entertainment Weekly with "The Originals" executive producer Michael Narducci, Season 3 had been highlighted as a journey of redemption for Klaus Mikaelson. However, the torture of pain and isolation imposed by Marcel Gerard (Charles Michael Davis) and the Tunde Blade could bring internal struggles between the old and the redeemed Klaus Mikaelson in "The Originals" Season 4.
Hope may play into that internal struggle since Cami O'Connell (Leah Pipes) advised Klaus Mikaelson in "The Originals" Season 3 that his daughter with Hayley Marshall is worth being better for. "The Originals" Season 4 would likely explore the dynamics between Klaus Mikaelson and Hope especially in the times he returns to his old self.
TV Guide cites Michael Narducci in saying that the final events of "The Originals" Season 3 could leave Klaus Mikaelson, Elijah, Kol and Freya quite unhappy. While this is one reason why the Mikaelson siblings would be feuding in "The Originals" Season 4, new addition Keelin (Christina Moses) might add fuel to the fire as fan theory suggests she brings new love for a Mikaelson.
A separate Parent Herald article cites that Keelin and Hayley Marshall could form an alliance in "The Originals" Season 4. Keelin would possibly be instrumental to bringing the Mikaelson siblings back by helping Hayley Marshall.
However as Hayley Marshall, a hybrid werewolf, would find out in "The Originals" Season 4 Keelin comes from a hunted line of werewolves, which is now all but extinct. Introduction for Keelin as cited by Deadline Hollywood teases dire consequences from the ally of Hayley Marshall meeting the Mikaelsons.
"The Originals" Season 4 release date has been reprogrammed by The CW to fall in with midseason 2017. Which Klaus Mikaelson do you think will win out in "The Originals" Season 4?
