|“||You are worth every sacrifice. And you are good. Period. Show me anybody who says otherwise and I'll eat 'em.||”|
Marcel was Hope's older adoptive brother via Klaus Mikaelson until The Bloody Crown, when Marcel openly declared war against The Mikaelsons. As a result of the war, Marcel imprisoned Hope's father for five years. He was also responsible for Hope's family slumbering for five years.
When they are reunited five years later, Hope and Marcel seem to get along fairly well. They bond over old stories about Hope's father, and Hope even gives him his century-old toy soldier back. Later, Marcel saves Hope from an attack on the compound, and she tells her father that she considers Marcel her friend.
Throughout The Originals Series
In From a Cradle to a Grave, after seeing what Mikael had done to his vampires at the Abattoir, Marcel ventured to the cemetery with the devil star, hoping to make Klaus bleed and take his blood. When he arrives, instead of using the star on Klaus, Marcel throws the star at Monique Deveraux in order to save Hope's life. He takes Hope and runs back to the Abattoir.
In Sanctuary, Finn tortured Marcel and asked about Hope, but Marcel was unable to remember due to Klaus compelling him to forget about Hope for her safety.
In Haunter of Ruins, after Vincent and Marcel saved the four missing children, they discovered that Hope was one of the intended children for the sacrifice as well. They needed to bring the Mikaelsons back to New Orleans so Vincent could purify Hope. Vincent and Marcel were discussing on whether to bring the Mikaelsons back or not. Vincent convinced Marcel by saying that Hope is a child and practically his sister. Then Vincent sent Hayley a message saying that he could fix what's wrong with Hope but they had to come back to New Orleans.
In Keepers of the House, Marcel asked Hayley for a favor, to tell Hope that she doesn't have to fear him and that she never did.
In High Water and a Devil's Daughter, Hope found Marcel's old childhood toys, she was playing with them and she was reading one of his poems. She asked Klaus if a little boy once lived there but he dodged the question and told her that he doesn't want her to play there because of all the dust and splinters. After a while, Hope went down the basement, where Klaus held Marcel captive. When she found Marcel, she gave him his toy soldier back. She asked him, if he was the little boy who used to live in their house, then Marcel told Hope about his history with her father.
Shortly after that, Klaus and Hayley were attacked by Dominic and his followers. Hope freed Marcel and he protected her, he told her to close her eyes and sing, so she wouldn't have to witness the violence.
Afterwards Marcel took Hope outside the abattoir to keep her safe, they were sitting on a bench together. When Klaus found them, Hope told Klaus not to be mad at Marcel because he is her friend.

- Marcel: "Oh, honey. You can't put that kind of pressure on yourself."
- Hope: "My family sacrificed everything to save me. I'm supposed to be worth it. I mean, I'm supposed to better, right? My dad thinks... That I'm broken. I don't think that um... I don't think that he loves me anymore."
