****** SPOILER ALERT ******
There are a couple of SPOILERS about season 2 of The Vampire Diaries & this is exactly what it is!!! I got this off of www.spoilertv.com (the tag to get to the exact page on www.spoilertv.com is with the SPOILER)!!! SPOILER:

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 의해 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 더 많이 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, 늑대인간 will be introduced 다음 season and one of them (probably Tyler?) will connect with a certain witch (Bonnie?) while trying to deal with how to cope with their 수퍼내츄럴 abilities.
