‘The Originals’ Season 4 Spoilers: Klaus And Elijah Throw A Party In Episode 6 ‘Bag Of Cobras’ [VIDEO]

The Hollow is here and it is determined to bring destruction to New Orleans. Last time on CW’s “The Originals,” the mysterious dark force that is shaped like a blue orb pitted Klaus Mikaelson (Joseph Morgan) against Marcel (Charles Michael Davis). Fortunately, instead of killing his surrogate son, the werewolf-vampire hybrid decided to hold him captive.

What will happen next on “The Originals”?

Well, Klaus and his brother Elijah (Daniel Gillies) will soon discover that The Hollow has employed a mysterious servant to do its bidding after killing Detective Will Kinney (Jason Dohring). Armed with this new information, the famous Mikaelson brothers host an elaborate party in order to lure the new threat out and discover its identity.

Of course, fans of “The Originals” already know that The Hollow’s new servant is none other than Sofya (Taylor Cole), Marcel’s new lover.

Joining Klaus and Elijah in the hunt for the new servant is Vincent (Yusuf Gatewood). According to the synopsis on TVGuide, Vincent feels a sense of responsibility for the resurgence of this dark magic. A clip released by The CW shows the witch reluctantly joining forces with Elijah to help him root out the servant and find a way to beat the new enemy. He invites Elijah in his house and gives him information about what they are up against.

Meanwhile, Hayley (Phoebe Tonkin) turns to Freya (Riley Voelkel) for help after uncovering information about who may be behind her parents’ death. She wants Freya to help her unlock her memories from the day her parents died.

Of course, it won’t be long before Klaus learns that Sofya is The Hollow’s new servant. The two dance together at the party and Klaus suggests that he should probably kill her then and there. Instead of backing down, Sofya dares him to try killing her.

In other news, Danielle Campbell is returning to “The Originals” as Davina Clare for one episode, E! Online reports. In the May 12 episode of the CW show, titled “Voodoo In My Blood,” Klaus and Hayley travel to the ancestral world after being summoned by the ancestors. There they come face-to-face with Davina and she is the one person who holds the secrets to stopping The Hollow.

The same episode in which Davina returns is also the one in which “Vampire Diaries” character Alaric Satlzman (Matt Davis) stops by in New Orleans to partner up with Marcel and Elijah. The former occult professor has tracked down a crucial artifact that could help the supernatural creatures in fighting The Hollow.

“The Originals” executive producer, Michael Narducci, told TVLine that this new evil force will explore everyone’s fears and weaknesses. Additionally, Hayley’s exploration of her parents’ death will give her a sense of why her life took the course that it did.

Additionally, Freya and Keelin’s (Christina Moses) relationship will continue to grow and a compelling journey is in store for Hayley and Elijah.

Narducci also teased that the Season 4 finale will see the supernatural creatures stop this new malevolent force but victory will come at a steep price.

“The Originals” airs Fridays at 8 p.m. EDT on The CW.
