KLAUS RETURNS TO HIS PAST IN NEW ORLEANS — Acting on a mysterious tip that a plot is brewing against him in New Orleans, Klaus (Joseph Morgan) makes a trip to the town he and his family helped build. Klaus’ questions lead him to a reunion with his former protégé, Marcel (guest star Charles Michael Davis), a charismatic vampire who has total control over the human and supernatural inhabitants of New Orleans. Determined to help his brother find redemption, Elijah (Daniel Gillies) follows Klaus and soon learns that Hayley (guest star Phoebe Tonkin) has also come to the French Quarter searching for clues to her family history, and has fallen into the hands of a powerful witch named Sophie (guest star Daniella Pineda). Meanwhile, in Mystic Falls, Damon (Ian Somerhalder) and Stefan (Paul Wesley) continue with their plan for Elena (Nina Dobrev), while Katherine (Nina Dobrev) reveals a surprising vulnerability to Rebekah (Claire Holt) and asks her to deliver a message.
LET’S MAKE A DEAL — Damon (Ian Somerhalder) and Stefan (Paul Wesley) try a brutal new approach to provoke Elena (Nina Dobrev) into turning her humanity back on, and Caroline (Candice Accola) is frustrated when her attempt to intervene backfires. When Elena figures out a way to call the Salvatore brothers’ bluff, they call for backup from a surprising source. Matt (Zach Roerig) gives Rebekah (Claire Holt) some unsolicited advice on her life choices, and she tries to help him in return. Caroline has a confusing and dangerous encounter with Klaus (Joseph Morgan), and Katherine (Nina Dobrev) is suspicious when Bonnie (Kat Graham) makes her an offer that she promises will benefit them both.
SOMETHING WICKED - As Graduation Day approaches, Caroline (Candice Accola) tries to distract Elena (Nina Dobrev) by focusing on simple tasks like sending out announcements, but Elena won’t be swayed from her new obsession. Sheriff Forbes (Marguerite MacIntyre) calls Damon (Ian Somerhalder) and Stefan (Paul Wesley) to the hospital, where someone has been attacking patients. Still trying to force Katherine (Nina Dobrev) to help her, Bonnie (Kat Graham) refuses to give up on her plan to defeat Silas. As a violent wind storm causes a power outage in Mystic Falls, ghosts suddenly appear – some with good intentions and some bent on revenge.
