Sarah was definately pregnant at that time, she just didn't know it. That explains why she was not eating, feeling very tired and having mood swings. Candice was the only friend Sarah had at school. Candice should make a comeback to Coronation Street. I think 1997 was probably the last time I went out trick or treating. In 1999 I stayeds at home on halloween and probably was this episode when it was aired, I can remember when Tina O Brian started playing Sarah Platt.
