Stefan and Damon decide on a new plan to deal with Katherine at the Lockwood's masquerade ball. Katherine calls on an old friend, Lucy (guest star Natashia Williams – Romeo!, She Spies), to attend the ball with her. Bonnie, Jeremy and Alaric all do what they can to help Stefan and Damon, but Katherine has a surprise planned that none of them could foresee. Things take an ugly turn when Matt and Tyler start doing shots with their friends.

With help from Elena and Bonnie, Alaric tries to decipher the meaning behind his recent discovery. Elena and Rebekah (recurring guest star Claire Holt) engage in a mean-girl power struggle, until Rebekah finally reveals some of her family’s ancient secrets and the violent past she shares with Klaus and Elijah (recurring guest star Daniel Gillies). Damon tries a reckless new approach to make a breakthrough with Stefan, and they’re both surprised by an unlikely ally.

On the night of the Homecoming dance, Rebekah (recurring guest star Claire Holt) opens up to Elena about why the evening is so important to her, leaving Elena with conflicting emotions. Caroline and Matt are both shocked at Tyler’s behavior throughout the evening. The night takes a surreal turn when Klaus puts his latest plan into action. Determined to outsmart Klaus, Damon enters into a dangerous partnership, leading to a terrifying turn of events. The band My Morning Jacket performs in the party scenes.

Alaric finds an unexpected ally to guide him on his dangerous new path, while Damon and Meredith (recurring guest star Torrey DeVitto) try to figure out what their next move should be. At the school’s 1920s Decade Dance, Bonnie asks Jamie (recurring guest star Robert Ri’chard) to go with her and, at Caroline’s suggestion, Elena asks Stefan to be her date. Caroline is pleasantly surprised when Tyler shows up at the dance determined to sweep her off her feet, but Klaus does his best to come between them. The dance takes a deadly turn when Damon and Stefan realize they need the help of Matt, Jeremy and especially Bonnie to undo a spell that could prove devastating for everyone.
