Aargh, I just changed my Gill Murray icon, but I'll change it back to give you Dodson & Murray, which someone ought to make as a prequel. (A lot of us ship them!) You can see the new one when you've watched season three.

I think Julie Dodson was a DCI, ie same rank as Gill Murray (and Gene Hunt), in the second season, though she comes back as a DSI this year. Can't remember anything about Bristol, though it was a year ago that I saw it - she was running another team in Manchester then, I think.
