Kate Carter is a member of the family who moves into a house where a "ghost" was haunting it.
She was first seen coming out of the car looking for service on her cellphone. Later on when she was in her bed, she noticed something near her hand and thought it to be her dog, Buster. Then she noticed Buster near the door, not by her hand. She looked beside her only to see a door close. She screamed and drew Sam and Dean back into the house. She told her parents what happened, and then she was rushed outside for safety. She later saw the girl in the field. Sam and Dean then went to scour the house while she and her family went to the shed for shelter. When her younger brother Danny went missing, she stayed with her mother and waited for the hunters to locate the boy.
