Greedy villainess Amelie Graham de Vanily
Amelie Graham de Vanily (Jeanne Chartier) is the villainess of "Felix", episode 3.23 of Miraculous Ladybug (airdate November 13, 2019). She was the mother of Felix Graham de Vanily, and the twin sister of Emelie Agreste, the missing mother of Adrien Argeste (one of the show's protagonists).
The episode began with Felix and Amelie arriving at the home of Adrien and his father Gabriel on the anniversary of her sister's disappearance. The backstory of the family revealed that Amelie's husband had recently died, and that Gabriel had not gone to the funeral, causing a rift between the formerly close Felix and Adrien. Amelie went on to reveal that she wanted Gabriel and Emelie's wedding rings, priceless family heirlooms, to be returned to her, much to Gabriel's displeasure.
The episode's plan saw Felix pretend to be Adrien and make insulting online videos towards his cousin's friends, leading to an attack by several akumatised villains. After finding out, Amelie expressed her displeasure with her son's actions and attempted to persuade Adrien to forgive him, which Adrien does following Felix's apology. After exchanging a handshake with Gabriel, Felix departed with his mother. While on the train to leave Paris, Felix revealed he had stolen Gabriel's wedding ring during the handshake. Amelie then turned heel and praised her son for his theft, having instructed him to do so. The villainess then told Felix that the ring was his now, as (in her mind) it had always been meant to belong to them.
