 Jessica bumps into her friend again, and is nostalgic for her old school. At school, Anna s had a key cut from the girls  toilet one, and finds it fits the boys  toilets too! Mrs. Keele is becoming increasingly stressed with the pressure of work. Mr. Parrot has a new tactic - bribery of mars bars - for handling Year 7. It s partially successful, but the sentence "Mrs. Keele is cracking up" is whispered around. Paula sees Joe with his arm around Jessica, and is decidedly frosty to him. Both Arnie and Sam, and Jessica spread the word that Mr. Robson and Martha are an item, after seeing them together at the theatre. Mr. Robson fails to persuade Martha to go out for the evening, but then Jessica tells them that there s a problem - boys are locked in the toilet! After school, Arnie and Sam wait again for the Animal Man to arrive, and they set out to follow him, to see where his animal supplier lives. They discover that he is going to a flat, and use walkie talkies to get Arnie to follow the Animal Man - unfortunately, the technology fails at a crucial point, leaving Arnie vulnerable. Jacko goes for practice with his band, but once again he is too late - he finds his old keyboard, the other band member tells him he bought it for £40. Arnie follows the Animal Man, but then his prey turns, and Arnie quickly dodges into another flat doorway - to his astonishment, it s Anna who lives there. Anna refuses to let him out until he divulges what he and Sam are involved with... The next day, it s Anna who s showing the initiative in getting evidence of the animal trading. The girls only drama workshop has a successful improvisation session. Everything is fine, but then the boys come back, and want back into the action. Jessica starts an improv session where a ball is thrown, and a word added to a sentence. Joe grabs the ball, and won t let it back, so Jessica takes his hat. There s a mad throng of boys around Jessica, reaching for the hat - and suddenly she screams. Mr. Robson and Martha run to investigate - Jessica shouting "who was it?", and runs into Martha s arms, sobbing.
