I think the writers of spooks made Lucas pretty lame in Series 8 for a reason. Watching Series 7 you see that he is finding his was back into the world of MI-5 and the only way for him to go is up. So in Series 8 you would think he would be better, right? Wrong. The last thing that the writers want, IMHO, is another Adam Carter. Lucas's character is supposed to be ambiguous, struggling, and always on the verge of a meltdown because of his background. He is, in a way, the "anti-thesis" of Adam. Adam had the wife, the son, and the swagger, but why have another "hero" like that? That would be boring. I suspect we will see Lucas did struggling and will not likely be section chief and that will add to his struggle....It's a rant...sorry if it doesnt make sense
