Grace is a professor seen only in "Do You Know Who You Look Like?", where Frank develops a crush on her. She manipulates him into taking care of her sister, Helen, who's in poor health condition thanks to Grace burning her skin, thinking her father will love her over Helen afterward. As Helen and Frank have sex, Grace walks in on them and fights her sister, thinking she's trying to steal attention from her again. At the climax of their fight, Grace takes both her life and Helen's by dragging herself and Helen into a fireplace.
