3x18: "The Devil Comes Here and Sighs"

Description: IT’S JAZZ FEST IN NEW ORLEANS — As the city celebrates its annual Jazz Fest, an unlikely team of Mikaelson foes joins forces to take Klaus (Joseph Morgan) hostage. Leading the charge to get their brother back, Elijah (Daniel Gillies) and Freya (Riley Voelkel) face off against a powerful force like none they’ve ever seen before, while Hayley (Phoebe Tonkin) and Cami (Leah Pipes) set their own risky plan in motion to rescue Klaus. Meanwhile, when Kol’s (guest star Nathaniel Buzolic) erratic behavior worsens, Davina (Danielle Campbell) has no choice but to turn to Marcel (Charles Michael Davis) and Vincent (Yusuf Gatewood) for help. Jesse Warn directed the episode written by Kyle Arrington & Michelle Paradise.
