Klaus (Joseph Morgan) and Elijah (Daniel Gillies) will band together to find out Lucien's (Andrew Lees) true intention in the upcoming episode of The CW series "The Originals."

In "I'll See You in Hell or New Orleans," TV Guide reports that the Mikaelson siblings will team up to uncover the progeny's motives in moving to New Orleans. After Klaus learns some unexpected details about Lucien's past, the hybrid is intent on unlocking everything he can in order to get the upper hand. To do this, he needs his brother's help. What will they find out in their snooping?

Meanwhile, the siblings will be rattled to learn of a growing threat when Elijah's old friend arrives in the city. Marcel (Charles Michael Davis) will be lured with a tempting offer by someone determined to stay off the radar. Who is this person and what does he want? Is he connected to the danger the Mikaelsons will soon face?

Last episode, Klaus spoke to Elijah and Jackson (Nathan Parsons) about the prophecy on the future of their family and wanted to confirm its validity. The two immediately set out to do his plan. Although Elijah and Jackson could not pass through the barrier created by the boundary spell keeping vampires from getting into Lucien's penthouse, they managed to wound latter.

Elsewhere, Davina (Danielle Campbell) was performing the spell to free the Crescent wolves from the curse during the full moon. Although Hayley (Phoebe Tonkin) was upset with her, as she could not be with her baby daughter Hope, she knew how important the ceremony was. The spell was starting to work on the wolves, but then witches came pouring from all directions, obstructing its completion. Hayley became thoroughly upset, and she went to see Klaus, screaming that all she wanted was to give their daughter a parent she could be proud of.

"The Originals" airs Thursdays at 9 p.m. EST on The CW.
