Kevin attends Norbrook Comprehensive School to give a Careers Talk, where he meets barrister and ex-student Adam Batty and airline pilot Nicola Smithson. After headteacher Leon Mayhew gives them all a tour of the school, Adam tells Kevin he was the fat kid at school and was badly bullied – he thought coming back would allow him to settle some old scores. Nicola and Kevin give their speeches but, when it’s Adam’s turn, he can’t do it. As Adam looks down at his tablet, the words start to distort and all he can hear are the kids chanting ‘Fatty!

When he finally talks, Adam remembers one P.E. lesson when he’d forgotten his kit and recalls how the teacher made him strip down to his pants and run 10 laps of the sports hall. Known as ‘Fatty Batty’ ever after, Adam identifies the bullying teacher… as Leon! As Adam reveals he now stands up for victims of bullying through his work, the kids applaud Adam – and boo Leon. Kevin congratulates Adam, who leaves with his head held high, his demons laid to rest.
