Damon (Ian Somerhalder) goes with Elena (Nina Dobrev) and Bonnie (Kat Graham) to visit Whitmore College, where Professor Shane (guest star David Alpay, “The Borgias”) is taking over the Occult Studies classes formerly taught by Bonnie’s grandmother. At a fraternity costume party, Damon takes advantage of the wild scene to give Elena a lesson in choosing a victim. Rebekah’s (Claire Holt) attempt to buy Matt’s (Zach Roerig) forgiveness falls flat, but she is intrigued by unexpected news from Klaus (Joseph Morgan).
