Last week’s Vampire Diaries revealed the source of “hot nanny” Seline’s heat — you know, actual flames of hell — but fans might want to save their gasps for the next big siren-related bombshell.

“You should be very worried about the twins,” Kristen Gutoskie tells TVLine of Caroline and Alaric’s magical offspring. “I’m sorry to say it — Seline definitely has some dark plans for those kids.”

But before you start hating on Seline too hard, remember this: Has this show ever had a truly irredeemable villain?

“I don’t think her evil acts necessarily have evil intentions,” Gutoskie argues. “She’s doing a lot of things without knowing any better. There’s also a part of her that envies humanity and doesn’t want to live a life in service to the Devil — it gets a little tiring. So there really are two sides to her personality.”

And it’s entirely possible that one of those sides might still appeal to the over-worked head of the Armory.

“I definitely think there’s some attraction between Seline and Alaric,” Gutoskie admits. “Despite all the dark stuff going on with the kids, there’s still a connection between her and Alaric. I think she likes feeling needed by him, feeling a part of the family, a part of something.”

As for our last image of Seline — chowing down on Georgie’s corpse — Gutoskie says it was just another of the many firsts she’s experiencing now that she’s part of this show.

“We had some turkey jerky and some ketchup, and we made a good concoction — and I had to eat a lot of it,” she recalls. “It was between that option and mashed-up fruit roll-ups, and I just didn’t want that much sugar. I had the choice, and I went savory over sweet.”
