Chris is disillusioned to find Joanna seems to still be seeing Josh. Lucy's father's new girlfriend has her son Liam over to stay. They go indoor-skiing, and Lucy gets on well with him. While they are there, Lucy's dad asks his girlfriend to be his wife - she asks for time to consider it. Lauren's grandmother comes to stay. Judi, Kelly and Sarah-Jane find some codes in one of the boys' notebooks, giving scores - but for who, or what? Judi is determined to find out what they mean. The next day, she's worked it out - it's their personal measurements to show their progress in developing their muscles. The lads are embarrassed to find the whole class knows, and their measurements are illustrated on the blackboard. Lauren takes her grandmother to school (not that she much say in the matter!) and she meets her classmates in the Art Room. Lauren's Gran has a word of advice for everyone, and Lauren hurriedly ushers her out. Joanna surprises Chris by entering the boys' loos, and pushing him into the cubicle. She evades his question about if she is still seeing Josh. She goes home with him, but Chris's dad is at the door, so he makes an excuse about giving her a chemistry book - he gives her the Bible and she leaves - then she dumps it in a trash can outside. At home, Lauren finds Andy looking depressed - he's learned that school in Barbados will be strict, with a uniform and three hours homework. Jessica visits Lauren, and Andy leaves them alone. Shortly after, all her other mates poke their heads round the door to wish her luck...
