There's no better source for Vampire Diaries spoilers and information than Kevin Williamson.
The producer spoke to E! News at last weekend's Comic-Con, opening up about everything from Katherine's return to the possible re-appearance of Isobel.
Sit back, take in these teases and then head over to our Vampire Diaries forum to discuss in detail with fellow fans...
Why did Katherine come back? She came back for Stefan. [It's] a bit of a game changer for the show. We have to find out how is this going to affect Damon and Stefan.
Will we learn more about Katherine? There's so much to still know about 1864. What happened? Why wasn't she in the tomb? How did she escape? Where did she go? Why did she come to Mystic Falls to begin with? What brought her to Mystic Falls? And so there are all those fun questions that we're gonna explore and how the Lockwood curse figures into it.
Will there be flashbacks again? Certainly we have three flashback episodes planned, and I'm guessing there'll be four.
Any more Isobel sightings? We haven't individually broken down the back 9 episodes so I'd hate to say no and then turn around and do it and make a liar out of me. So I would say not in the first 12.
What will Tyler's role look like? Tyler's going to sort of learn through the help of his Uncle Mason who comes to town in the very first episode, who and what he is. He's gonna learn about the curse, who he is and how he responds to it.
