Betty Kenner was a patient at Seattle Grace Hospital. After a crash, a head injury caused her memory to reset every 30 seconds.
Betty was confused when they arrived at the hospital. She kept asking what had happened, even after being told several times. Betty was taken for a CT which showed a subdural hematoma. They scheduled surgery to relieve the pressure. ("Dream a Little Dream of Me, Part 1")

The girls described themselves as the happiest married people alive except when their husbands smoked. Unfortunately, after the crash, her husband Vincent Kenner died.
