Kate Burton is an actress who plays Ellis Grey, Meredith Grey's mother who has Alzheimer's on Grey's Anatomy and recently she played Rose on Rescue Me who is helping the Chief Jerry Reilly (Jack McGee) who has a wife on Alzheimer's. I think the Rescue Me role came first, but not only does Alzheimer's follow Kate, affairs with chiefs do too. It seems Ellis had an affair with the hospital chief Richard Webber (James Pickens Jr.), divorcing with Meredith's father. While it seems the other show is alluding to an relationship between Rose and Jerry (who also has a gay son).
