Dubious thanks, I've had time to rewatch the car hitting Hana and the abduction again and agree, what was that other poster (different forum) on about? So, that's a useless distraction.
What I have noted from the bits of Episode 1 that I've rewatched is that Farmer is unlikely to have been genuinely guilty of the rape of Jade. I say that because of his learning difficulties and willingness to say what others want to hear and because he initially said she was complicit. When asked about it, she's shifty with her 'yeah well then he said he done it, so what's the problem?' I think there must be more to her than we've seen. The door to her house has broken panes boarded over and her first words before anything are 'what's he done now?' He being the father of her child presumably. I really want to know who she's involved with. It must link with a story about gangs on the estate and possibly balaclava thugs.
Roz at first seems insistent on treating Farmer properly. At the interview with Kate in prison she seems caring towards him. I'd forgotten he has a wound on his temple at this point and was limping, which he puts down to having 'one of my falls' That's when the conversation about making sure he's looked after better takes place.
After Roz's conversations with Hilton, her attitude changes then about the clean up rates. I think we have some of the best and the worst lines in this episode. Hilton about the public's concerns 'they're killing us on Twitter' oh please and Hastings after Hilton's tv announcement 'ACC Hilton's audition for Crimewatch went well' 
I think Roz's whole demeanour when she's sitting on the edge of the bed at home is really strange and not what you'd expect at all. She's a senior, experienced detective, not a rookie on her first case. It's been months, not years. She says 'It's over. It's finally over' That's definitely got to relate to something we don't yet know. It also kind of links with something Ted says to Kate and Steve, implying that Roz was put on Operation Trapdoor for a specific reason.
I'm convinced that it's impossible to work this series out if you haven't seen the ones before.
I have a question as well, Tim's position was Forensic Coordinator, Roz is Detective Chief Inspector, yet when they meet in the corridors, he addresses her simply as Roz? Can someone explain how that comes about?
It's such a shame that episode 1 expires before episode 6 airs as I'd really like to binge watch the series as a whole. I suppose that'll make for a bit more revenue though.
