 Jessica is still reeling after an unknown boy groped her during a drama session - initial suspicion falls on Joe. Her father regrets moving his children to Grange Hill. Mrs. Keele is in no mood to find someone handing out racist leaflets outside school. She has a meeting with the Arnolds, but the general consensus is to work out who was responsible before making decisions. Jessica s Year 7 brother, Arnie, believes the rumour about Joe, and is determined to have it out with him. He encounters Joe s girlfriend Paula, who heads off in search of Jessica.

She has to take the class herself. All is well to begin with, but then Anna sets off her annoying talking watch demonstrating it to Janice on her left. "it s 9:40 am" it repeatedly says, until Mrs. Keele has had enough, and tries to work out whose it is. It is obvious that it is Anna s, and in a rapidly deteriorating voice, demands that Anna gives over the watch and leaves the room. Anna refuses, shouting back that it s not fair. To everyone s shock, Mrs. Keele clutches at her throat, and lives up to her name - keeling over and collapsing onto the floor. "You ve killed her," whispers Janice...
