Katerina Graham has teased that none of the characters on The Vampire Diaries is safe.

Speaking to the Los Angeles Times, Graham revealed that viewers will be surprised about what happens on the show.

"I think no-one's safe at this point," she said. "That's why it's so important to watch the show because you're going to be completely taken by surprise. Completely.

"Every character is going to surprise you. There's not one character on this show that doesn't get a curveball. So no-one is safe. Not one person. Not I, not Elena, not anyone. No-one is safe at this point. You're going to be really shocked."

Graham also revealed that the show will feature an "amazing" scene between Bonnie and Damon (Ian Somerhalder) in an upcoming episode.

"It'll get everyone talking," she teased. "It's just a can't-miss moment. It definitely has to deal with a great part of Bonnie's decision on what she's going to do... it's an incredible moment on the show."

Graham has already confirmed that a series regular will die before the end of the season.

The Vampire Diaries returns for a new episode tonight at 8/7 on The CW in the US and on Tuesday at 9pm on ITV2 in the UK.
