"The Originals" Season 4 is set to see the return of the Mikaelsons but not until Hayley finds a cure to their conditions. In the process of reviving the original vampire family, Hayley may need to face off with Team Marcel because Klaus' former protege will not let any Mikaelson return to New Orleans. But it seems that Marcel's plans are doomed to fail after five years as the new promo revealed that the dead will rise and it may be referring to Klaus and his siblings.

"The Originals" Season 4 new promo showed Hayley as she figures out a way to heal her family. She opened a casket where Elijah lies and the vampire-werewolf hybrid is seemingly determined to fight to bring her former lover back along with the rest of the Mikaelsons. That said, she's not afraid to cross Marcel who is now the ruler of New Orleans as per Entertainment Weekly.

The new promo also highlighted Klaus, of course, who is still in Marcel's dungeon. It remains to be seen how he could free himself given his evidently weakening state. However, the promo clearly stated the dead will rise again so that gives fans some hope that Klaus and his siblings will soon return to New Orleans.

Meanwhile, an earlier report here at MobilenApps already revealed that Hayley's cure for the Mikaelsons on "The Originals" Season 4 would be an apparent success. Additionally, the family is going to reclaim their reputation and aim to rule New Orleans again, reportedly. But what's also interesting is the reunion of Hayley and Elijah who might face some new complications in their relationship again.

"The Originals" Season 4 air date is set on March 17. It will fill the time slot of its beloved parent show, "The Vampire Diaries," which is now on its Season 8 with an impending finale on March 10. In the meantime, see the new promo of "The Originals" Season 4 below.
