Keith is worried that Tom is being bullied at school. In order to attempt to make himself and Tom look more aggressive, he buys a 4x4 from Shaun (Neil Fitzmaurice), a fellow AA member, and uses it to stand up to the bully's mother. Keith tells Anita that he is taking the car for a test drive, but Anita demands he returns it. Keith later learns that his overheard comments about one of Tom's overweight friends have led to another boy being bullied. Shaun later tells Keith that he is likely to be laid off, because his workmates bully him. Keith advises him to stand up for himself, but this leads him to relapse into drinking. On the way back from AA, Shaun vomits in the car, meaning he cannot return it. (thetvdb.com)
