Still upset by the way events ended at the Halloween haunted house, Elena does her best to stay away from Stefan, but Lexi gives her some unsolicited relationship advice. Meanwhile, both Elena and Jenna are surprised by a change in Jeremy's behavior in the wake of Vicki's "disapearance". But only Elena knows that Damon's mind-wipe powers did something to her brother. At Damon's insistence, Caroline tries to get his medallion back from Bonnie who continues to study her wiccan heritages with her grandmother's help. Elsewhere, Damon's offer to help Sheriff Forbes has sudden and tragic results since she does not know that he is the vampire that she and her circle of hunters are looking for.
