When Bethany Platt's teenage father Neil was killed in a car accident in September 2003, Sarah attended the funeral and made hesitant contact with Neil's mother, Brenda. She had been hit with a double blow in that her husband had left her a couple of years before and Sarah agreed that the grieving woman could start seeing her granddaughter. After a period of time, it became clear that Brenda's losses had made her unstable and when Sarah discovered that she was taking Bethany to see Neil's grave and hysterically passing her off as her own daughter, she banned her from further contact.
However Sarah forgot to take Brenda off the list of known guardians at the nursery and when she and Todd Grimshaw went to collect her at the end of one day, they discovered that she had already been taken. They rushed round to Brenda's house to find it in darkness and no one answering the door. A Neighbour came out of her next-door house and although she said that she didn't really know Brenda then went on to prove that she was a keen observer of her actions when she said that she saw her draw her bedroom curtains each day at 4.00pm for an afternoon nap like clockwork.
