During dinner table conversation the evening after Tim's murder, Nick said he hadn't been home because he went for a drink with Jimmy - first mention of that name - so I am assuming for now that Jimmy couldn't have been involved with Tim's death.
When Roz finds out that Tim had supplied a photo of BM to Steve, she breaks down in the garage, not sure if it was realisation of what was happening or because weirdly, there was something going on between her and Tim. I can't see really believe that but her reaction was like someone who had been betrayed. The only emotion she has really shown. On the otherhand, it could be that she realised its not going to be as easy as originally thought to frame Farmer and it isn't actually 'over' - only just beginning.
The type of relationship she has with her husband and with Hilton is being slowly revealed each episode. Nick has turned out to be a wuss and Hilton, a pervy smarmy boss in it for himself. When he comes in to get a catch up on Trapdoor, he says to Buckles something like, "At least we can still call them prostitutes" referring to Buckells comment about Leonie and further embedding the sexist undercurrent - Roz refers to them as women but as soon as she's off the case, boys can call them prostitutes.
I am just wondering if there was something between Roz and Tim and we will find out they were actually having some kind of relationship. Very unLOD but stranger things have happened. He was so eager to dob her in to AC12.
What if Nick turns out to be Jacky Laverty's business lawyer.
I have realised I am spending too much time thinking about this damn programme and I actually haven't a clue !!
