Is he lady Evelyn's disciple?

"Lady kana, I want to see lady Evelyn for one last time before leaving" Cathrine insisted as she looked at kana with a pleading gaze, she wanted to know why lady Evelyn stop in the middle of the Conversation when she was talking about her mother, it doesn't make any sense to her and that gesture left her in a daze.

Cathrine was barely teen when she lost her mother and in her last time when she was on her death bead her mother stopped talking or seeing anyone because of her mysterious a disease that could be dangerous to others if they expose to it, no one was allowed to talk or see her even her own children and Cathrine were not special as she also prohibited to see her own mother, only king and the court healer are allowed to see the queen in her last time and even after her death she can't able to see the face of her mother, her mother left her vulnerable afterall she was everything to her.
