KRISTIN KREUK: I think the whole concept is that we all do. It’s not necessarily a dark side, but there are things about ourselves that we want to hide and that we think are bad, and sometimes they are destructive and violent. Even if it’s something where you say something to me and I get pissed, and I say something mean to you, that’s violent. Catherine has got a lot of stuff that she’s buried down, and her impulse towards revenge, which is a violent act that isn’t okay, she understands is an impulse towards stopping these people that hurt her mom. She believes that somehow it’s going to make it better. But Vincent, in some ways, knows that it won’t. No matter how much you exact justice in the world, it won’t make the feeling go away. That is her darkness.
