Ian Somerhalder, Nina Dobrev and Elena and Paul Wesley

While we wait patiently for the next new episode of Vampire Diaries (Thursday, March 25, 8/7c on the CW), TVGuide.com talked to executive producers Julie Plec and Kevin Williamson about where the show is heading this spring. Spoiler alert: They reveal key details about the season finale.

Vampire Diaries' Ian Somerhalder on Elena vs. Katherine

TVGuide.com: How will the love triangle between Stefan (Paul Wesley), Elena (Nina Dobrev) and Damon (Ian Somerhalder) evolve in these next episodes?
Williamson:
One of the most important things Julie and I wanted to do this season is cement the love between Stefan and Elena. It's that love story that will be the anchor of this entire show. We have to earn that.

TVGuide.com: All signs point to Alaric's wife, Isobel (Mia Kirshner), being Elena's mother. When will we learn more about that?
Plec:
The signals are pointing very much in that direction.
Williamson: In regards to what happens, there's still a few surprises with all of that.
Plec: The next episode is very much about Elena's search to try to get to the bottom of who this woman is and how, if at all, she connects to Alaric.

David Anders joins Vampire Diaries

TVGuide.com: We'll soon be meeting Jonathan Gilbert. How does he come into play?
Williamson:
Uncle John [David Anders] comes to town for one reason and then you slowly start to realize he could be there for another. He has a hidden agenda, just like everyone else in town.
Plec: He's stepping in to fill the shoes on the Founders' Council, with there being a lack of Gilberts representing the founding families. Uncle John gets in there to stir things up.
Williamson: One of the surprises is that he shows up, interestingly enough, just after that tomb is opened. How convenient.

TVGuide.com: Was he in the tomb?
Williamson:
Maybe...not.
Plec:
Oh, gosh no. [Laughs]

TVGuide.com: The tomb is still open, isn't it?
Plec: Yes, and
there's some good that comes out of there and there's some very, very, very bad that comes out of there.
Williamson: And there's some stuff that launches us into a whole new story line.

TVGuide.com: Jeremy (Steven R. McQueen) is starting to figure out that there are vampires. Will that put him in danger?
Plec:
Jeremy has seen too much. We're exploring how he starts to dig a little bit deeper and put the pieces together of what exactly vampires are and if they're real. Is this pretty girl that he kissed in the woods, who we saw little veiny eyes on, is she one? The vampire has a crazy allure, as we've seen between Elena and Stefan, so is he going to fall for her or have some feelings for one of his own?
Williamson: Or is he going to fall in the footsteps of the Gilberts that came before him?
Plec: Which are no friends of the vampire.

Vampire Diaries, Supernatural and Gossip Girl among early CW renewals

TVGuide.com: What should we expect in the season finale?
Plec:
What we've been building to from the beginning — it's something we took directly from the books — is this event called the Founders' Day Celebration, which is the anniversary of the founding of the town. We're looking into big period costumes and Civil War reenactments and maybe some parade action with some big floats. It's going to be the big event that connects us back to 1864 and what went down back then. It messes things up so when we come back in Season 2, everyone has a reason to tune in again. There are nine "oh my God" moments.
