Aya: Compelled someone to clean up your burning husk, and never thought of you again.
— Marcel and Aya in A Walk on the Wild Side
Throughout The Originals SeriesEdit
In I'll See You in Hell or New Orleans, Aya arrived at Marcel's hideout where he and some of his vampires were gathered. She attempted to make a proposal to him but he ordered his vampires to get her out. Aya beat down the young vampires easily despite their determination to defend themselves. Aya was impressed that Marcel was the last one standing and held his own despite that she was three times his age. She told him that she admired his determination to protect his home and reputation but that they'd speak somewhere more appropriate. She poisoned him with a toxin she'd made herself on a pointed ring, knocking him out.
Aya brought Marcel to a large house where she woke him up with water and gave him a blood bag to help him recovery. She told him that there was plenty more where it came from and that her and her friends could help his vampires get daylight rings as well, getting Marcel's attention. She explained that she knew his story and offered to help him turn New Orleans into what it should be, with him as the king. She told him that the group she belonged to was The Strix, an ancient society of vampires.
In A Walk on the Wild Side, Aya stole his daylight ring during the Strix gathering in order to set him up for his test to be part of the Strix. He eventually figured out who stole the daylight ring (Aya herself) and he passes the Strix's test. Later on, they converse alone after he won his test to be part of the Strix. He asks what would happen if he lost and Aya said that she would have someone clean up his dead body and never think about him again. They shortly share their first kiss after this.
Aya later steals Rebekah's body as a part of the Strix's plans, but it is unknown how Marcel feels about Aya after this or even if he knows she stole Rebekah's body.
In The Other Girl in New Orleans, Aya threatens him with death if he doesn't take down Elijah. He ends up taking him down, but he lies about Elijah's allies coming to rescue him and proves his loyalty only the Mikaelsons.
In A Ghost Along the Mississippi, Aya calls high members of the Strix, including Marcel, to a mandatory and immediate meeting. Aya hired a witch named, Ariane, to use magical cards to test each member's loyalty. Marcel was clearly worried being he was only in the Strix as a spy for Elijah and Klaus. However, a member before him was revealed to be the betrayer out of the group of members and Marcel was revealed to be loyal to the Strix and Aya's orders, due to Ariane's spell.
In Wild at Heart, while Elijah and Aya fight for the title of leader in the Strix, Marcel steals the ancient pact made by them themselves and becomes leader over both Aya, Elijah and the rest of the Strix's members. Aya respectfully backs off her fight when Marcel wins their "duel" for leadership and accepts Marcel as her new leader.
In A Streetcar Named Desire, the episode opens on the two discussing strategies in how to go forward with their plans on unlinking Elijah and Klaus' sirelines. Aya promises Marcel that things would be better once the Originals are dead. This is the last time the two ever interact with each other on screen before Aya's death.
