Margaret 'Peggy' Gallagher, also known as 'Grammy', is the formidable mother of Frank and matriarch of the Gallagher family, being sent home from prison after lying about her health. She immediately goes after an old dealer who profited from her arrest and demands money from him, which Frank ends up ruining by only getting a quarter of the promised 200,000 dollars. The mother and son are shown to have a frosty relationship and she soon makes an enemy from Sheila, who she even tries to shoot. Despite her hostile nature, she tries her best to reach out to the Gallagher children, giving Fiona money and showering Carl and Debbie with gifts. However, when Peggy tries to run a meth lab in the basement, Fiona and Frank plot to get rid of her only to discover that she really is dying of cancer and doesn't have long to live. She eventually dies when she gives Shiela permission to kill her, but not before sending out money to Frank's brothers instead of Frank himself. She tried to get hit by a bus to sue the city, only it failed. After her death she is cremated, and Frank doesn't want anything to do with his mother's remains. Her ashes where brought back home by Monica the morning after Peggy's mourning. During this time Mandy was pregnant, which made Terry very upset. Frank began to prepare a smoke made from his mother's ashes, Terry breaks in the back door looking for Ian, and slobishly knocking out the bag of ashes from the table and on to the floor. During her time in prison, she was known as "Bodybags". Her actions in the Gallagher and Jackson households make her one of the two main antagonists of season 2.
