One thing I’ve not seen mentioned (or have I missed something) is the short scene where Lisa, Miroslav and the young crim are sat in the car, they talk about him “passing his exam” and “going for the interview”.
Is he going to join the police?
Are all three of them coppers and the young one going for promotion?
Or have I missed something obvious?
The young criminal is Ryan, who was the young kiddie in the first series who helped torture Arnott. I think he is trying to join the old bill, and become the new caddy, as it seems to be the same route Dot Cotton followed.
