Diamond's Links
Selected her as his assistant mostly because he knew that the fact she was trying to use him to flee Clockwork would mean she would be fully under his thumb and hers to control- no one would come help p her. Gave her the name Zirconia forcibly (mocking her- she's only a shadow of himself) and coerced her into her marriage with Aventurine (by threatening her place). Consistently emotionally abused her by telling her she is as despicable as she is, and using the threat of people who hated him who targeted Cora as a reason for her to stay shackled to him. Doesn't even see her as a useful pawn- just an amusing one that he keeps around because of his ego, a demonstration of his power and influence.
Her boss. At first she saw him as her salvation, but realized he used her the same as her father did to her. He molded her to his desires- her name, behaviors, personality, and appearance. Works very efficiently for him in fear that he will cast her aside one day, leaving her with nothing. Greatly afraid of him and is incredibly quiet around Diamond. Currently is petrified at how he will react to Cora refusing to come back to Pier Point and abandoning her post. There is a tiny part of her- which she constantly berates- that foolishly wishes that Diamond did actually care for her like a daughter.
