RACE FOR THE CURE — Elena (Nina Dobrev) and Rebekah (Claire Holt) take off in search of Katherine (also played by Nina Dobrev) and find themselves in a small town in Pennsylvania, where Elena has a surprising encounter with another old acquaintance -- Elijah (guest star Daniel Gillies). Stefan (Paul Wesley) and Damon (Ian Somerhalder) are both concerned about Elena’s state of mind and are determined to do what’s best for her, but she makes it clear that helping her will be difficult. Damon is not sure how to react when Stefan reveals his unexpected plan for the future. Meanwhile, in Mystic Falls, Klaus (Joseph Morgan) receives Caroline’s (Candice Accola) reluctant help and comes to a new understanding of Silas’ powers.
