"Tonally, it's a little different," Morgan tells TVGuide.com. "The Vampire Diaries is a coming-of-age story and "The Originals," like Julie [Plec] has said, is more like The Lost Boys, embracing the nature of being a vampire where you party all night and sleep all day. It's really about these guys who want to be vampires as opposed to the guilt and remorse the weight of that which comes with The Vampire Diaries."
When Klaus receives a message from Katherine (Nina Dobrev) that a witch in New Orleans is plotting against him, he travels to the Big Easy to reunite with his former protégé Marcel (Charles Michael Davis) and perhaps reclaim the city that was once his.
"Klaus is a fan of manipulation, and he makes a few direct challenges throughout the episode, and there are a few displays of violence," Morgan says. "The interesting thing to see will be who he's willing to work with to get where he wants to be and what commitments he's willing to make to them. Klaus is very much a lone wolf, he'll side with someone for a certain amount of time and then next thing he'll be siding with someone else against them."
Joining Klaus on his new mission is his brother Elijah (Daniel Gillies), who will be elated to learn he has a reason to keep his family together. "There are elements of the story line that come out which will absolutely explore more of a potential for vulnerability in his personal life and his relationship with family," Morgan says. "Elijah really wants to bring the family together, and he's come to a point where he's realized that the strength they have is with each other. Rebekah and Klaus are very much at odds, so Elijah finds himself a little bit of a middleman."
Although the future of "The Originals" remains to be seen, Morgan says he can't think about the possibility of the pilot not going to series, even if Plec told us she has "a glorious character story for him to tell in the world of Mystic Falls" should the spin-off not happen.
"Everyone at the moment is moving forward as if it will go to series, which I think is the way to go," he says. "I have to proceed that way, because however 'glorious' the [story line] is, I think it'll be a disappointment for me to happen."
And as for Klaus' future as it pertains to Caroline (Candice Accola) and the decision he will make about Tyler (Michael Trevino)? Morgan tells us, "I don't want to say either way where it's going to go, because that's ultimately Klaus' contribution to the finale, making that choice, but I feel like it's not the end of the Klaus-Caroline storyline, but I feel like it's a satisfying place to leave it at the end of the season."
Regardless, Morgan admits that the backdoor pilot never could've happened had it not been for the fans. After all, Klaus was originally intended to be killed off in Season 3!
"I'm so excited for people to meet the new characters and see this new world and what this could be, should it go to series," Morgan says. "I don't think I would have this opportunity if the fans hadn't responded so warmly to Klaus, an old villain, so I really appreciate everyone's support and I hope this is something of a thank you to them."
