The Vampire Diaries executive Julie Plec has dropped hints about another death in the upcoming fourth-season premiere.

Speaking to Entertainment Weekly, Plec explained that the show's season four opener will feature a "powerful, surprising death sequence".

She said: "When Alaric Saltzman (Matt Davis) told the council that the town was filled with vampires, [he] told a lot of details about a lot of people that in the first episode back we'll see have created a little bit of a domino effect."

Speaking about Klaus (Joseph Morgan) who escaped his own apparent death by possessing Tyler Lockwood (Michael Trevino), Plec said: "[Klaus] definitely has an agenda that he wants to service which we'll start to get a hint at about three episodes, four episodes in.

The fourth season of The Vampire Diaries debuts on The CW on October 11.
