Sean Renard, possible sexual relationship
She was known, at least by reputation, by Hexenbiester in Europe. ("Mr. Sandman")
She was in on Renard's plan after she learned about it from her daughter. She initially seemed to be a very loving and nurturing mother. As Adalind returned home having failed her task her mother was initially sympathetic. However when she discovered that her daughter failed and became a human, she was unsympathetic to her daughter and had no problem disowning her.
Renard instructed her to protect Juliette Silverton because Juliette tied Nick to Portland. Though she disowned Adalind, it is clear Catherine is upset about her fate: she hints that Renard's treatment of Adalind encouraged her to make mistakes. Catherine apparently feels that Nick killed her daughter, rather than just made her human.
She collects the ingredients to bring Juliette out of her coma on Renard's orders. Renard comes to collect the white lumpy concoction in a jar. Soon afterward Kelly Burkhardt goes to interrogate her, and although she reveals the existence of "a prince," she refuses to name him. The two enter a fight—Catherine with a piece of kitchen cutlery and Kelly with a magazine. Catherine is accidentally killed by Kelly Burkhardt when she is pushed headfirst into two large mirrors.
