The Mikaelsons finally had a breakthrough in preventing the prophecy that would wipe them out in last week's episode of The Originals. Klaus (Joseph Morgan) and Hayley (Phoebe Tonkin) discovered that Lucien's (Andrew Lees) Kingmaker Properties was making moves against local werewolves - a sign that Klaus' first sire had a bigger plan that was only now coming to light.

Morgan steps behind the camera to direct Friday's episode of The Originals that will see Klaus and Hayley having to work together to figure out Lucien's true motives, while Elijah (Daniel Gillies) and Finn (Casper Zafer) head to Mystic Falls on their own mission. If the Mikaelson family can figure out what Lucien and Kingmaker are up to, they stand a chance at defeating the prophecy and rescuing their sister Freya (Riley Voelkel) from her captors.

Morgan talked to TVGuide.com about the challenges ahead for the vampires, growing closer to Hayley and what it will take for all of the Mikaelsons to be together again. See his answers below.

What was Klaus's worst fear when he realized that Lucien and Kingmaker Property were still at large?

Joseph Morgan: There's definitely a feeling of responsibility because he sired Lucien. It would have to be his child that was the problem child. The feeling of having trusted [Lucien] and welcoming him back to a certain extent and not having seen what was there right under his nose, there's a sense of dread in that. Klaus pushes with Hayley to find what is Lucien's goal here. What is the idea? What is he trying to do? Everything is working on that front in the episode.

It takes Finn and Elijah to Mystic Falls and it takes Klaus and Hayley all over the country investigating multiple Kingmaker facilities.

Klaus is the most vulnerable we've ever seen him since he's separated from his sire line and in exile from New Orleans. Will this humble or change him in any way?

Morgan: He's pretty self-destructive. Perhaps he was under a delusion for a little while that the vampires he sired were not attacking him out of some sense of loyalty or love. Obviously, it was more 'he dies, they die' kind of situation. I think he's realizing that now. Rather than feel vulnerable or perhaps he should make amends to all of them, he'll go on the attack which is his default setting. I don't know what there would be for him to learn from this or to change except to be more wary and less trusting of people, if he can be.

How will his time on the run with Hayley strengthen their relationship?

Morgan: My goal during the episode was to bring them together as a team, to unite them under the banner of Hope. That was a running theme for the episode, also for Finn and Elijah — two brothers who are at odds. The arc of the episode is about bringing them together and helping them understand each other a little more and work together. That's what I tried to achieve with Klaus and Hayley as well. The end of the episode sees Klaus and Hayley in a better place than we left them, which is progress in the Mikaelson household.

Does he have any regrets about leaving Cami (Leah Pipes) behind?

Morgan: He's very much resigned to that fact and very focused on the mission at hand. The danger is right there in front of him and they are unraveling this plan of Lucien's now. He feels so close to the truth and finding out what Lucien's goal is and finding out what this is all about. I think that's really what's first and foremost in his mind.

The Originals: Kol's return will make the prophecy that much more difficult to decipher

When he figures out Lucien's plan will it allow him to come back to New Orleans?

Morgan: It will unite [the Mikaelsons]. It will bring them together. Noting unites the Mikaelsons like a common enemy or a common threat. They'll fight amongst themselves until the cows come home but if someone else threatens their family or presents a threat, then watch them all pull together to break them down.

What are the chances that we'll see a full Mikaelson family reunion this season?

Morgan: There's just so many of them! It depends if you're talking cousins and second cousins and aunties and uncles. We've got Aunt Dahlia and mum and dad. That would be a family photo to remember, the Mikaelson family photo. If you're referring to just the siblings, I think it would be nice. Don't hold your breath, though. We'll see all of the siblings this season but I don't know if we'll see them all in the same room.

What is Lucien's reaction going to be when he finds out what Klaus has done to Aurora (Rebecca Breeds)?

Morgan: Not good. He's not going to be happy about that. Sometimes I think these villains, these people, I feel like, "Why don't they just kill the antagonists of their lives?" Instead they go, "I'm going to tell you my plan and then lock you away," in traditional super villain manner. I suppose, for vampires or immortals, the idea of death is a release and they don't want to offer that to each other. Lucien will be pretty angry, but he's already pretty angry with Klaus.

The Originals airs Friday at 9/8c on The CW.
