The synopsis for the episode teased that Dr. Wes is going to let out his “secret weapon” — which we’re pretty sure is Enzo, who is most likely the Augustine Vampire that killed Elena and Caroline’s roommate, Meghan. But what does Dr. Wes want with Elena? Does he want to turn her into another one of his vampire-blood-sucking vamps? Or will he try to do something else? After all, Grayson Gilbert was Dr. Wes's mentor. Would he really torture his daughter,, vampire or not?
Meanwhile, Stefan is going to confront Aaron (Shaun Sipos) about Elena's whereabouts. We know we should be worried about Elena, but we're pretty sure Aaron is the one most likely to die in this episode, given Stefan’s past and the terrifying lengths we know he’ll go to make sure Elena is safe. He's ready to kill.
