Trisha asks if Cathy and Susi were in the same form and Susi says yes, but she is now in R1 with Penny. Trisha then asks what Miss Summers is like and Penny feels like she is too easy going. Trisha and Cathy then explain to Susi and Penny how Mr Mitchell got told off by the headmaster when Tucker Jenkins and his friends smashed a window and Mr Mitchell wasn't there. Mary notices a miserable Judy and Trisha tells them the reason she is like that is because her mum is making her move to Brookdale and she doesn't want to go. Judy feels it will be awful as a couple of girls she knows say it's terrible and Cathy says she knows a couple of girls at Brookdale and they think it's fantastic as the students can wear what they want, including make up and jewellery. Cathy asks when she is going and Judy says that she has to meet her mum at Brookdale after school for a look round and Cathy offers to go with her, joking if that the boys are any good, she will swap there herself. Trisha also agrees to go with her and Cathy.

The police inform the school that a man has been chasing female students from Brookdale and warns the girls at Grange Hill that they are to walk home in pairs, especially through Burdette Park. After Cathy and Trisha deliver an errand for the school secretary, Cathy ignores the police warning and goes through Burdette Park on her own and she is chased by the man who has been watching her lately outside the school. Mr Mitchell and the police officer make it in time. The man says he is Cathy's father.
