Via TV Line:

As viewers saw in the Season 2 finale, Stefan is finally taking a walk on the wild side –- a journey Paul Wesley told me he is quite ready to (sorry) sink his teeth into, when I spoke to him and Ian Somerhalder at The CW upfront event. “For two years now I’ve been really good, so I’m really excited to have a bit of a good time,” he said, “like Mr. Ian Somerhalder does every day.” Speaking of the proverbial devil, does Damon’s portrayer believe his TV sib can be great at bad? “He can definitely bring it,” Somerhalder attested. He added with a wink, “That’s because I teach him.” The question is, how much of Stefan’s darkness will be directed at Elena, who has just locked lips with her beau’s bro? Says Nina Dobrev, “I knew that once that happened, all hell would break loose…. There will definitely be consequences!”
