It's looking like the show will suffer a MAJOR re-structuring for Season 5...
We know that Klaus and Hayley will move to New Orleans, and hopefully Rebekah and Elijah will be there too.
Tyler has left Mystic Falls, and Michael Trevino says that if he comes back it will be as a Guest actor only. Jeremy and Carol Lockwood are dead, and I will be surprised if Rudy Hopkins survives the end of the season. The Gilbert house is burned to the ground. Although they are still alive we have barely seen Liz and Meredith. And I hope that Kat Graham will dedicate more time to her singing carreer.... Maybe Bonnie does not survive this whole Expression Triangle Zombie Appocalypse thingy.
So, will Elena, Matt and Caroline graduate and move to college - just like Buffy and Willow?
New scenaries, new main characters, worries about bills to pay, tough teachers and evil brewing just below the college library?
