Jeremy (Steven R. McQueen) gets a break from the mysterious new history teacher, Alaric Saltzman (guest star Matt Davis, Legally Blonde) and introduces Alaric to Jenna (Sara Canning).

Bonnie (Katerina Graham) is having terrifying dreams about one of her ancestors.

Despite Elena’s (Nina Dobrev) efforts to smooth things over, Bonnie and Caroline (Candice Accola) continue to argue over the medallion. When the girls hold a séance to help them decide what to do, the results are stranger than any of them expected.

Matt (Zach Roerig) comes to Caroline’s aid when she needs a friend. Damon finally reveals to Stefan the stunning reason he has returned to Mystic Falls.

Why do you think he returned? I’m interested in seeing how Bonnie’s ancestor, Emily the witch is going to do in this episode? Emily was Katherine’s handmaiden
