The Toronto Sun has an interview with Candice Accola.
Check it all out here.
Here is an excerpt:
Early in The Vampire Diaries, Caroline was the bitch. There’s no other way to put it. But as the rookie season progressed, something interesting happened with Caroline, who is played by Candice Accola.
Over time, Caroline became a three-dimensional, even sympathetic character. When she behaved in a bitchy way, viewers started to feel sorry for her, rather than despising her.
We have to assume the writers on The Vampire Diaries saw something in Accola that allowed this gradual transformation to occur.
