This week's episode 6 of "The Originals" season 4 will feature Klaus (Joseph Morgan) and Elijah (Daniel Gillies) hosting a party to lure the one sent to kill them.

In "The Originals" season 4 episode 6, titled "Bag of Cobras," Klaus and Elijah will discover that the Hollow has sent a mysterious envoy to deliver their death. Upon finding out, the two will organize a party, believing that it will be the perfect opportunity for them to bait whoever the Hollow's envoy is and reveal his/her identity to the attendees.

As Vincent (Yusuf Gatewood) puts the blame on himself for the resurrection of the Hollow, he will agree to the plan of the Mikaelsons, believing that it is one of the best things that he can do to make up for his mistake. While the warlock is prepared to use his magical powers against the Hollow's envoy, spoiler reports claim that he will not be ready for the threat he has to deal with.

While it remains unknown who the Hollow has sent to kill the Mikaelsons, it is suspected that it may be Sofya (Taylor Cole), Marcel's (Charles Michael Davis) girlfriend. As seen in the promo for the upcoming episode, Sofya tells a colleague to look for Marcel, who has been hidden by the Mikaelsons after capturing him, while she says that she will take on Klaus. As Sofya has the vine that can kill Klaus and the rest of the Mikaelsons, it is said that there is a possibility for her to finally use it as she may be the person the Hollow has sent to deliver the death of the Mikaelsons.

Meanwhile, the synopsis of the upcoming episode 6 also reveals that Hayley (Phoebe Tonkin) will seek the help of Freya (Riley Voelkel) so that she can remember the night she was orphaned as her parents were killed. As this can mean that Phoebe will have to re-experience what happened that fateful day in her life, it remains to be seen if Freya will agree to help her.

"The Originals" season 4 episode 6 airs this Friday evening, April 28, at 8 EDT on The CW.
