Read the official summary of episode 4×18 of The Vampire Diaries, “American Gothic,” in which Daniel Gillies returns as Elijah.

In the upcoming The Vampire Diaries episode “American Gothic,” the cure will still be on everyone’s minds, as Elena races after Katherine – only to unexpectedly run into Elijah! Read the description, which has been released by the CW:

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.

Do you think that Elijah and Katherine are working together?

This is only two episodes before the big The Originals pilot launch episode, which will see Klaus, Elijah and Rebekah all traveling to New Orleans – potentially taking them out of the race for the cure. So who will end up getting it?

The Vampire Diaries returns next Thursday at 8/7c with 4×16 “Bring it On.”
