E!Online Spoiler Chat with Kristin Dos Santos has the scoop about more characters that may die or come very close to it by the end of season 3.

MandyLee: How about something juicy on The Vampire Diaries?!
How about the fact that people are totes gonna die? This is the scoop executive producer Julie Plec drops our way: “There’s definitely going to be some jeopardy by season’s end. Certainly, many of our characters are going to come face-to-face with their maker at some point before the season is over. The question of whether they meet and shake the hand and get dragged away with their maker is a whole other question.” So it sounds like some deaths might not stick? And others will?
