Ekaterina Roskova

I was seventeen years old and did not want to die.

Ekaterina Roskova is played by Alexandra Serova. She is a secondary 'antagonist' in the later seasons of Mabel.

Season Six
Ekaterina appears first in Primogeniture under the name Aconite. She speaks about how no member of the Underhill is happy to see Anna or Mabel. As the season goes on, it is revealed that she believes herself wholeheartedly to be the daughter of the King; however, she is mistaken due to suffering from amnesia.

She was born in Russia to a political dissident father who died when she was a teenager. After her father's death, she was sent to the United States, specifically the boarding school St. Olga's. After years at the school, when she was 17, she was turned into an experiment by Aurora Silver. Referred to as Subject 6163 during the experiments, she was tortured at length, specifically with both knives and poison. After an unknown amount of time, she succeeded in contacting some form of god while the cult tortured her. After making contact with the "fractured" being, she dies and ends up in the Underhill, not remembering anything about her life. The King is the first being she sees, and she assumes him to be her father.

She becomes a member of the Court. When Anna takes the King's throne, she decides to challenge Anna for what she perceives as her birthright. She nearly succeeds, but concedes the throne after Anna and Mabel play her tapes from when she was stuck as 6163. Anna and Mabel explain her true past, and she calls Anna "your majesty", showing a newfound loyalty to the girls.
