Thursday's episode of "The Vampire Diaries" entitled "Best Served Cold" will feature a party where the Salvatore brothers will attempt to kill Julian, Lily's one true love who was brought back to life in the previous episode.

Lily hosts the dinner party to prove to her sons that they can live happily with the Heretics, but Damon and Stefan aren't on board with the idea. In the previous episode Valerie dropped a bombshell on Damon when she revealed that it was Lily who gave Kai the idea to link Elena's life with Bonnie's. Now, all Damon wants is revenge.

As for Stefan, he is not pleased that Lily's lover Julian was responsible for the death of his unborn child.

Elsewhere in the episode, viewers will finally learn the true identity of the vampire who has taken over Jo's body. In a recent interview with TVLine, executive producer Caroline Dries revealed that the spirit who has taken over Jo's body is someone familiar to "The Vampire Diaries" fans.

On what to expect in the upcoming episodes, Dries added: "We have this mythology with the Phoenix Stone and what it actually does, so the mystery for the next episodes will be how Faux-Jo — or whatever you want to call her — can integrate into the world we've created at Mystic Falls and at Whitmore."
