Hana was def running for the bus because she called out for it to stop, having said goodbye to her friends getting on a different bus.
Nick knew Steve was in his way to see him, of course, he can't have been on the phone to Nick the whole way there, didn't he leave a voicemessage first? Jamie only told Maneet when she went to show him the car they saw at Ifield's flat was Nick's....
But Jamie is some kind of plant.
I think we'll see more from Jodie.
Farmer was def a set up.
(S1 and 2 spoilers below....)
I think Jackie's (Gina McKee) body was left frozen in that flat (but doubt it can still be there, this is years later). There was another body in s2, the one Denton thought was Carly (the 15 yo missing person who Denton saw giving the senior officer a blowjob, who then used his wife's speeding offence as cover), but wasn't.....so.....where is Carly!? And who was that body?
Is Hunter def dead from s2? Cos, I'm just not sure he is.
