Let the guessing games begin!
To what end? Theorize away as you take a close look at the scene:
The last time this former couple interacted, of course, Bonnie was using her magic to fake Jeremy's death. She then took it upon herself to help Klaus live inside the body of Tyler.
Oh, yes, the resident Mystic Falls witch has "tapped into some darker stuff," as creator Julie Plec previously teased, and the question now remains: Will she continue down this dark path? How far might she go?
Just a couple more questions to ponder, spurned on by this early look, as we anticipate the return of The Vampire Diaries on October 11.
