The residents of Mystic Falls have already had to deal with Alaric Saltzman going from heroic history teacher to evil supernatural slayer.

Will they soon need to brace themselves for another journey of a local favorite to the dark side?

Asked about storyline for The Vampire Diaries Season 4, executive producer Julie Plec told E! News last week that a lot of debate is raging over Bonnie's future on the show.

"She's tapped into some darker stuff," Plec said, referring to the spell Bonnie pulled off to bring Jeremy back to life. "I don't know which way we'll go with her in season four. Do you go down a road even though people did it really well, do you really want to do that? Or do you ignore what other people did and do it because it's right for the character? I'm interested to see where we land on that as writers."

Plec's concern, interestingly enough, stems from Buffy the Vampire Slayer and how that series dealt with the character of Willow.
