The 24-year-old, who plays a high school witch named Bonnie Bennett, said that "anyone can die" on the popular CW series.
She told TV Guide: "In our first meeting with the director and writers in Atlanta, we were sat down and we were told bluntly that this isn't The Elena Diaries, this isn't The Stefan Diaries and this isn't The Bonnie Diaries, this is The Vampire Diaries, and anyone can die and anything can happen.
"Every episode somebody dies. Yeah, there are going to be a lot more deaths, a lot more sex, a lot more magic, and fire and power."
Jasmine Guy was previously confirmed to portray Graham's grandmother on the show, which was recently picked up for a full season order.
