I saw that episode. The main character girl is Jo Patterson, and her best friend (the boy) is Danny Foster. His mother Robyn is a veterinarian. Jo's mother is Maggie, her father is Frank, her Grandad is Mike, who's a police sergent in the police dog squad, and her younger brother is Chris. It was a scout outing for boys and girls. The teacher I think might be Brian Horton. But I can't remember. Jo went to get more water because Chris had left it behind and on trying to find her way back to the group of girls, headed by her father Frank, she got panicked and lost. Then she slipped down a sloping rockface and not far below her was a sheer drop! Danny and Kelly, the German Shepherd, went to look for her and found her. It was a good episode. When I first watched Kelly (that episode is in the first series), and Kelly II I wrote down summaries of what happened in each episode. Enjoy the next episode Nebo, there's more great ones to come!!!
