I can think of a story for Klayley. Hope Mikaelson grows resentful towards Marcel for causing the downfall of her family and becomes the Tribrid, the most powerful being in the world. When she defeats Marcel and humiliates him in front of everyone, Hayley, her mother, who has always tried to make Hope forget that hatred, tries to make her daughter reconsider, Hope does so and manages to understand that if she could give her father the opportunity to be better, she would do so. This makes Hope discover a way to go back in time, specifically to the date where days before her father broke his curse, so her father will not have problems with the inhabitants of Mystil Fall in the future. She can make her mother and father be together and also have her family. What do you think of the idea? (The Mikaelsons died at the hands of Marcel, that's why Hope hates him so much)
