The relationship between the Upgraded Original vampire, Marcel Gerard, and the witch, Freya Mikaelson.
Despite not interacting much they're platonic with one another and were allies being they were both a part of the Mikaelson family. However, when Freya, along with Elijah Mikaelson, led the plan to use Davina Claire's spirit in order to kill Lucien Castle, this effectively ends Freya's friendship with Marcel. Also, this sparks Marcel plans to try and destroy the Mikaelson family after Elijah helps enact the serum within Marcel to turn into an Upgraded Original vampire. Freya desperately tried to thwart Marcel's plans from succeeding in destroying the Mikaelson family by throwing herself and her siblings into a temporary slumber so that Hayley Marshall-Kenner could help the rest of the Mikaelson family be cured of Marcel's wrath.
Throughout The Originals Series[]
In Exquisite Corpse, Marcel worked with Freya to rid Rebekah Mikaelson's new host body of the powerful, vengeful witch, Eva Sinclair. They were successful; Rebekah now has complete ownership of Eva's body.
In Ashes to Ashes, they ally to stop Dahlia once and for all. During this time, Freya attempts to kill Marcel, but eventually stops because she wants to be a part of the Mikaelson family. They win against Dahlia's rage eventually.
In You Hung the Moon, Marcel and Freya converse about the best clubs in New Orleans. They appear closer in friendship at this point in the series and no longer enemies/frenemies.
In Beautiful Mistake, they allied together to infiltrate the Strix, which worked out in the end.
In Where Nothing Stays Buried, Freya and the rest of the Mikaelson Family (except Kol) betray Marcel by using Davina Claire in a spell, which ultimately killed Davina. Marcel blames Freya and the rest of the Mikaelsons for Davina's demise. This episode marks the end of Freya and Marcel's alliance and familial relationship.

In No Quarter,
In Haunter of Ruins, they do not have any direct interaction with each other, however, Freya believes that Marcel will still come after her family, despite the fact that he chose to show them mercy, as she is still using Keelin to make an endless supply of antivenom for the Upgraded Original Vampire's venom, believing he may have given his followers his venom to be used against her siblings, later, she realizes the only way to cure the symptoms is to destroy the source; as she wants Keelin to help her find a way to permanently kill Marcel.
In I Hear You Knocking, Freya gives Klaus a dagger capable of killing Marcel in case Marcel came for him. She later on cast a boundary spell to imprison Marcel after Klaus knocks him out in the same spot he imprisoned Klaus in before.
