Ekaterina Roskova

Ekaterina Roskova, also referred to as Aconite, is played by Alexandra Serova. She is a secondary 'antagonist' in the later seasons of Mabel.

Seasons Five & Six
Aconite appears first in episode thirty-three, Primogeniture; she's monologue-ing 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. She was born in Russia to a political dissident father who dies; she is taken to the States, Massachusetts specifically, and becomes the vessel of a literal god. edit tmmrw
