The Vampire Diaries: The House Guest Preview

We showed the promo photos for the upcoming episode of The Vampire Diaries called The House Guest. The episode will air this Thursday. You can watch the preview at the bottom of this post.
I wonder how they will build up towards the season finale? They do have a way to go before then, but it should be fun to see how they lead up to it. They have some big steps to make this season, in order to wrap it up.
What do you think about the preview? Are you looking forward to the episode air? I wonder how these writers come up with the show’s storyline? It would be fun if they offered a behind the scenes look at how they come up with these storylines. I think the show’s fans would be happy to get a chance to you how the writers work. How many of you hope that they have a big surprise at the season’s end?
