Klaus, Stefan and Rebekah wreaked a bit of havoc after returning to Mystic Falls in the most recent episode of The Vampire Diaries. Klaus turned Tyler into a hybrid by figuring out that the original witch had tricked him. He didn't actually need Elena to die in order to successfully created hybrids - he just needed to feed them her blood. But after using Elena as his own personal blood bank, he was forced to flee town after learning that Damon and Katherine had were going to sic Michael (the vampire hunter) on him. But before Klaus left, he managed to completely turn off Stefan's humanity, leaving Elena very sad that her boyfriend is lost to her. In a last minute shocker, Stefan arrived back home and announced that he was remaining in Mystic Falls.
Jeremy realized his ability to communicate with ghosts was helpful since Anna was the only person who could help Damon and Katherine find Michael and defeat Klaus. Matt also firmly entrenched himself in the supernatural elements when he voluntarily died so that he could communicate with Vicki in order to help his friends. Fortunately, Bonnie was able to bring him back to life.
In the October 20 episode of The Vampire Diaries, Elena, Bonnie, Caroline, Tyler and Matt return to school for their senior year. While the rest of them are reeling from recent events, Tyler seems on top of the world. Damon is very upset that Stefan has returned home to carry out Klaus' latest assignment, and the others are shocked when a new student joins Alaric's class.
