When Roy first meets Alistair, Alistair is with a girl. When he walks past Roy after the conversation ends, the girl is not with him.
Moss's 8+ club name is Word but during the Street Countdown battle, Prime calls him Moss not Word.
At the 8+ party, Roy is rebuked for requesting a beer as alcohol is not acceptable. However its clear that other people at the party are drinking alcohol (cocktail glasses etc). Though it could be possible that they are drinking non-alcoholic versions of those drinks.
