"I think the solicitor is implicated somehow, he was really freaked out when Shaun went to see him after being arrested for the abduction, really freaked out like he didn’t want anything to do with him. He was the one who supposedly found that the Helmand footage was dodgy."
I found the whole thing where the footage was shown to Shaun in front of his solicitor (Hannah's colleague) and the colleague didn't know Hannah had been abducted was not very realistic but was for effect, of course.
I can totally get why the solicitor would be freaked out to see Shaun.
I think we know Shaun is innocent because if he knew where Hannah was he would have told the guy when he thought his friend was being tortured but it would be a real twist if he was guilty!
His ex's new partner seems a bit of a twit! not getting the girl away from the TV!
I don't think Lia Williams' character was married to the guy Rachel is shagging, I think she is married to someone else but she worked for him and also had an affair with him at some point. Just a guess.
