As you all know, this morning was the CW upfront in New York City, where the network presented its 2010-2011 schedule to advertisers and press. Nina Dobrev, Paul Wesley, and Ian Somerhalder all walked the “green” carpet to represent The Vampire Diaries.

In season 2, the Stefan/Elena/Damon will evolve into a Stefan/Katherine/Elena/Damon quadrangle and surprisingly it will be Stefan, NOT Damon, who will be the most affected by Katherine's return: it will turn out he's not as over her as he thought he was. Elena will come to come to terms with the fact that she may have developed feelings that are more than friendly towards Damon. Damon, on the other hand, will be busy devising a plan with the Council of the Founding Fathers to take down Katherine.
And yes, werewolves will be introduced next season and one of them (probably Tyler?) will connect with a certain witch (Bonnie?) while trying to deal with how to cope with their supernatural abilities.

"Julie and creator Kevin Williamson's overarching goal for season 2 is to integrate the other characters outside of the love triangle, especially Tyler Lockwood (Michael Trevino). "Tyler is crucial to this mythology," Julie said. "The werewolf element is crucial to this story. Season two is big time about the Lockwoods, so the first thing that happens is Mrs. Lockwood steps in as interim mayor." And if Jeremy (Steven R. McQueen) survives (wink, wink), Julie alluded to that fact that he and Tyler could share a strong connection. Another new bromance on the horizon will be Stefan and Matt (Zach Roerig). Yes, Elena's ex and current love will become "true blue" friends."

"When last we left Damon he was smooching Elena, or so we (and he) thought until moments later when she whipped out that big butcher knife and let us know she was really Elena's look-a-like, naughty vamp Katherine. So will deceived Damon continue to woo Elena in the upcoming season? "The only thing I can say about them for season two, is that it's going to be a very profound triangle," Julie said rather coyly, though she did drop a few hints. "Damon's still got a long way to go until he's man enough to deserve Elena. But he has a strong pull, a strong draw." But with Katherine stalking Mystic Falls, Julie says to expect more of a "love square." Though I was never good at geometry, that does sound rather intriguing, no?

And speaking of the ancient vampire diva, Julie confirmed that Katherine and Elena are indeed related (unlike in the book series), and that their connection will continue to be revealed. "Our position is very much that the bloodline is the Pierce bloodline. Isobel is part of that, as is Elena. Elena looks like Katherine, they're doppelgangers. That's the big question that will continue to be asked deep into the second season."
