The CW has released an official description for the March 18 episode of The Originals.
The episode is called "Moon Over Bourbon Street" and here is how they describe it:
UNNATURAL ALLIANCES — After accusing Klaus (Joseph Morgan) of doing nothing while their control over the Quarter crumbles, Elijah (Daniel Gillies) makes a move to take matters into his own hands. He receives an intriguing offer of support from Francesca (guest star Peta Sergeant), a beautiful woman from a powerful New Orleans family. In an attempt to bring the warring factions of the city together, the Mikaelsons throw an extravagant party, where Klaus offers Jackson (guest star Nathan Parsons) a tempting deal, Elijah and Hayley share a dance, and a violent fight comes to a surprising end. Finally, even as Marcel (Charles Michael Davis) works on a new path to power, he continues to help Cami (Leah Pipes) deal with her Uncle Kieran's tragedy (guest star Todd Stashwick). Michael Robinson directed the episode written by Michelle Paradise & Christopher Hollier (#117).
