[Traumatic pregnancy, Mother death] Shelby has a baby boy, Jackson Jr., but soon develops kidney failure requiring regular dialysis. Around Jackson Jr.'s first birthday, Shelby undergoes a successful transplant with M'Lynn's donated kidney. Shelby recovers but four months later, Jackson arrives home to find her unconscious. Shelby is comatose, having contracted an infection in her central nervous system due to the suppressive therapy that keeps her body from rejecting the kidney. After doctors determine Shelby's condition is irreversible, the family jointly decide to remove her from life support.
