Pamela had broken up with Joe before the baby was born, but after re-evaluating her life choices, she had decided to come visit him and his parents for Christmas, so that he could see his 5-month-old son and they could discuss getting back together again. Joe lived with his parents a few hours away from her. She was 16-years-old, not yet an adult herself and had been living with her mother. He was just a few years older than her. Joe's parents were more than happy to let her stay as long as she wanted.
