I too think Graeme is a touch of genius, I think he should get more lines.
On the David Platt front, I thought myself, "well Gail's tough love act didn't last long did it?" Surprise, surprise, remember he just lived at the house as she couldn't be bothered to chuck him out and handle the consequences and she'd washed her hands of him no more than 2 weeks ago. If that little t**d was mine I would have killed him myself by now!
Also, why is Martin Platt never mentioned any more, no matter what the little evil one has done, there is never any phone call to his father to bring him up to speed or ask his opinion?
