It looks like Klaus (Joseph Morgan) and Hayley's (Phoebe Tonkin) daughter Hope will have a bigger role in "The Originals" season 4. A casting notice suggests that she might be all grown up as well.

Based on the said casting notice, the supernatural series is looking for a young actress who can play the role of an unidentified "young daughter," who is believed to be Hope.

According to previous reports, the little one will be the key to help Klaus and the rest of the Mikaelson family survive after what Marcel (Charles Michael Davis) did to them out of revenge.

Hope happens to be the world's first werewolf-witch-vampire hybrid and is expected to inherit an immense amount of power from her parents. Even as a baby, Hope already showed her abilities such as sensing danger.

Since "The Originals" season 4 will likely show Hope as a young kid, it looks like fans will get to see more of the powers and abilities she possesses owing to her unique heritage.

Hope's extraordinary vampiric traits that come from none other than Klaus might be explored in "The Originals" season. Because of her heritage, her blood is powerful enough to heal herself and others.

Hope also inherited Klaus' ability to sire vampires and hybrids. She definitely has massive power to tap into and waiting to be uncovered. Fans can imagine her healing ability to be of use in "The Originals" season 4.

Fans will remember that in the season 3 finale, Hayley left New Orleans with baby Hope in search of a cure to bring back Elijah (Daniel Gillies), Rebekah (Claire Holt) and Freya (Riley Voelkel) to eventually save Klaus.

As she finds the solution, she will realize that she has the key to their safety all along. That being said, Hope may finally use her powers in the new season.

"The Originals" season 4 premieres early next year.
