In this series finale, Sav's quest to get Jonjo arrested for Andy's murder draws suspicion from Costello and Sarge; his damn emotions seem to be impairing his ability to do his job. He is angry that Amanda has agreed to pose as a student in an attempt to catch two men who have been attacking young women - especially as she will have no back-up - and when the set-up goes wrong, he decides to take his own course of action. BBC1 are getting round to showing Russell Brand: From Addiction to Recovery which previously aired on BBC3. Prepare yourselves for diatribes and exceedingly erratic editing.
