"The Originals" season 2, episode 7 spoilers reveal that Kaleb will share his secret to Davina as Klaus will try to come to the defense of Elijah.

Last week, it was revealed that Esther has been selling the first born of each generation in her line to her sister. But her meddling didn't stop there as she threatens to put a wedge between Klaus and Elijah, who seemed not himself after the abduction. There's also the revelation that a brother or sister of the Original could still be alive, said Hypable.

Of course, this won't be the last that Klaus and Elijah would have some confrontation particularly with the revelation that the latter killed Tatia, played by Nina Dobrev, whom both brothers pined for. Will that change how Klaus will view his brother if Elijah's secret is out? That remains to be seen especially since Nina Dobrev already made a guest appearance in "The Originals" season 2.

"The Originals" season 2, episode 7 spoilers can be gleaned from the synopsis which reads: "When Klaus (Joseph Morgan) discovers that Elijah (Daniel Gillies) has been afflicted by Esther's (Sonja Sohn) magic, he heads to the bayou in search of an antidote, but quickly realizes he's not alone."

"Armed with intel gathered by Aiden (guest star Colin Woodell), Hayley (Phoebe Tonkin) teams up with him, Marcel (Charles Michael Davis), Cami (Leah Pipes) and Josh (guest star Steven Kruger) and launches a plan to take down Vincent (guest star Yusuf Gatewood) by exploiting his one weakness."

"Meanwhile, with Esther determined to carry out her plan, Vincent and Kaleb (guest star Daniel Sharman) are forced to reconsider their own strategies," the synopsis added. "Intrigued by Davina's (Danielle Campbell) unwavering attempts to create an unlinking spell, Kaleb lets her in on some secrets from his past and brings her to a place he frequented in 1914."

The episode is directed by Jesse Warn and written by Carina Adly Mackenzie & Christopher Hollier.
