What will happen when Marcel (Charles Michael Davis) sees Davina (Danielle Campbell) alive and in good health in the upcoming season of "The Originals"?

Last installment, the vampire went crazy when the witch was killed by the Mikaelsons. Marcel vowed to get revenge and he eventually succeeded. He arranged a trial for Klaus (Joseph Morgan) and had him staked in the heart with the Tunde Blade. The hybrid is bound to sleep for eternity, but not in peace. For every second the dagger stays embedded in his heart, he will feel the most painful of pains. Klaus is meant to regret all of the sins he has committed for centuries.

As for the other Original siblings, Marcel wanted to kill them all, but Freya (Riley Voelkel) managed to save them with a clever spell. Their lives are now tethered to Klaus', which means they will wake up from their slumber once he does. In the event that Klaus is killed, so will they. Marcel wanted to teach the Mikaelsons a lesson they would never forget. They killed his family and they must pay the price.

Davina is gone, but Campbell previously hinted to TV Line that her character still has some unfinished business to attend to. Is it possible that she will be resurrected?

"It's hard to say for sure. A lot of it depends on story arcs and availability down the line, but I think it's going to be up in the air. [The producers and writers are] still going to be figuring out the next storylines once they return for the next season, so it hinges on what'll happen a few months from now. But never say never!" she said.

Meanwhile, Hayley (Phoebe Tonkin) may get the help of a renegade werewolf who will cross paths with the Mikaelsons as they flee New Orleans. It was previously revealed that Christina Moses would play Keelin, whose family was hunted until only she remains. Fashion & Style posits that the two werewolves will find solace with each other as they each flee from their enemies. Hayley needs to keep the Mikaelsons' bodies safe, while Keelin has to hide from those who want to kill her.

"The Originals" season 4 is expected to return midseason next year.
