"She's kind of like the ex-girlfriend from hell," The Originals boss added with a laugh. "She sounds perfect for Klaus."
Now that we know that it was Elijah's fault -- via his fist compel spell -- that Aurora and Klaus were torn apart, the relationship between the Mikaelson brothers is shattered, once again.
"Interestingly enough, we've found out that there's a great sin from Elijah's past," Narducci said. "Maybe Elijah has stood by Klaus' side for all these centuries due to a sense of guilt for something that he did. Maybe the noble, beautiful, honorable Elijah has some flaws or chinks in his armor."
The showrunner warned that things are about to get "very complicated" between Klaus and Elijah. "They need to stand together because what's coming at them is far worse than each of them are to one another," he said.
So what can fans expect now that Klaus' first love is wandering the streets of NOLA? Get ready for some heated conversations -- and kisses! -- between the long lost twosome.
"[In episode six,] we also see part two of the reunion between Klaus and Aurora and how their relationship will evolve in the now," Narducci said. "And it ends with the single most frightening combination of romance and fear that I think we have ever put on screen."
"It is the most chilling, and the most romantic, and the most sexy, but the most horrifying ending we've ever done at the end of [an] episode," Narducci continued. "We get to see basically everyone we care about and everyone we love put in extreme situations of jeopardy."
The Originals airs Thursdays at 9 p.m. ET/PT on The CW.
