Fans should be ready for Klaus's (Joseph Morgan) bloodthirsty turn come "The Originals" season 4. While he seems to be safe from the pain brought about by the Tunde Blade which pierced through him, others around him might not.

Morgan revealed in an interview with TV Overmind that he will get into a murderous psyche in the next season. However, the actor believes that his daughter will play a part in bringing him back.

The actor said that it was life-changing experience for Klaus to have a child, who quickly became his everything. "The Originals" season 4 will further explore his relationship with his baby Hope.

"His unconditional love of his daughter is something that changed him forever and so I hope his connection to his humanity will be through her," Morgan said.

When "The Originals" season 4 hits the small screen, there will be a five-year time-jump, which means that baby Hope has grown into a little girl.

All those years, Klaus did not see one of the most important persons in his life grow. During the San Diego Comic Con, Morgan said that it will be a nerve-wracking moment for Klaus to meet his child.

Hope's connection to her father is not the only thing that can help snap Klaus back to his true self. With the abilities she has owing to the fact that she is a child of an Original Hybrid, it is safe to say that whatever power she has will be of great use in "The Originals" season 4.

Meanwhile, Morgan also talked about how his character will deal with the fallout of his friendship with Marcel (Charles Michael Davis).

When asked what Klaus' disposition will be, the actor answered that the character will approach the issue "violently," especially after what happened in the previous season.

"He loves Marcel like a son and Marcel betrayed him. And some might say it I justified in doing so, I think it's been a long time coming," the actor said, adding that Marcel has grown tired of giving the Mikaelsons a chance to make him believe in them.

"Maybe Klaus understands a little where he's coming from. That does not mean he's going to act any less violently though to Marcel. I feel like the end is coming for these two. I'm excited to see it," Morgan went on to say.

"The Originals" season 4 premieres early this year on The CW.
