It's a shame you can't do both, Flowers!
I have just spent an hour or so in the company of Lucas North, and find myself thinking what a shame they did what they did with him. There was so much there that could have been explored and I mean character-wise, not twiglets etc.
But there again, I am inclined to believe that less is more when it comes to the life-span of characters in a TV series. What I would like is for him to return for one episode, so it can be revealed that all this John business was drug-programmed into him, a layer under the layer so to speak, so his memories were false, and his actions controlled by a puppet master. Finally he could die some beautiful death, like Guy, and then everyone would be happy.
